#

first, im starting UBS 1.1 support!

#

USB*

honest pier Oct 26, 2025, 7:32 PM

#

usb 3.0 is a superset

indigo needle Oct 26, 2025, 8:06 PM

#

honest pier usb 3.0 is a superset

we are still not on USB 3.0 yet

honest pier Oct 26, 2025, 8:07 PM

#

if you implement XHCI, you get USB 1.1 and USB 2.0 for free

indigo needle Oct 26, 2025, 8:07 PM

#

honest pier if you implement XHCI, you get USB 1.1 and USB 2.0 for free

oh

honest pier Oct 26, 2025, 8:07 PM

#

that way you don't have to have separate drivers for 1.1 and 2.0 controllers

#

also, USB 1.1 is virtually nonexistent

indigo needle Oct 26, 2025, 8:08 PM

#

honest pier also, USB 1.1 is virtually nonexistent

why?

honest pier Oct 26, 2025, 8:08 PM

#

because it wasn't popular during its time

indigo needle Oct 26, 2025, 8:09 PM

#

honest pier because it wasn't popular during its time

i think your talking about 1.0

honest pier Oct 26, 2025, 8:09 PM

#

and it didn't really have a long lifespan, USB 2.0 was released just 2 years later

indigo needle Oct 26, 2025, 8:09 PM

#

1.1 is when USB started getting attraction

honest pier Oct 26, 2025, 8:09 PM

#

started, yes, but it still wasn't very popular

indigo needle Oct 26, 2025, 8:09 PM

#

yes

honest pier Oct 26, 2025, 8:09 PM

#

definitely not anywhere close to where it is today

indigo needle Oct 26, 2025, 8:10 PM

#

USB is not very everyday for me tho bc i use internet and internal storage

honest pier Oct 26, 2025, 8:10 PM

#

you use a keyboard don't you?

indigo needle Oct 26, 2025, 8:10 PM

#

honest pier you use a keyboard don't you?

yes

honest pier Oct 26, 2025, 8:10 PM

#

it more than likely uses USB

indigo needle Oct 26, 2025, 8:10 PM

#

oh yea its USB-C

honest pier Oct 26, 2025, 8:11 PM

#

even a lot of network cards use the USB protocol in some way or another

#

yes, even PCIe ones

indigo needle Oct 26, 2025, 8:12 PM

#

honest pier yes, even PCIe ones

PCIe is its own port tho

#

UPDATE: i started USB 1.1 coding

honest pier Oct 26, 2025, 8:29 PM

#

also FYI, EHCI (USB 2.0) doesn't support USB 1.1 controllers

#

also, why are you doing USB 1.1?

indigo needle Oct 26, 2025, 8:30 PM

#

honest pier also, why are you doing USB 1.1?

because its the easiest, and its a start to USB

#

also

#

im doing USB this early into the kernel

#

cuz currently the OS runs on a USB

#

and i need to read data from USB to proeed

#

proceed*

west patrol Oct 26, 2025, 8:31 PM

#

just do xhci

#

you're just going to triple the work if you wanna implement newer stuff

indigo needle Oct 26, 2025, 8:32 PM

#

west patrol just do xhci

hmm let me look into it

west patrol Oct 26, 2025, 8:32 PM

#

well. you should've looked in to it before writing any usb related things.

indigo needle Oct 26, 2025, 8:33 PM

#

west patrol well. you should've looked in to it before writing any usb related things.

i still have barely started into USB tho

#

alright, i think im gonna implement XHCI

west patrol Oct 26, 2025, 8:34 PM

#

please do

chilly sleet Oct 28, 2025, 11:41 AM

#

after taking a short break for school

#

im now continuing developemtn

#

(school just wasted my time), but atleast i dont study (i use chatgpt, next best thing)

past rose Oct 28, 2025, 7:19 PM

#

indigo needle (school just wasted my time), but atleast i dont study (i use chatgpt, next best...

how do you pass exams without studying?

indigo needle Oct 28, 2025, 7:19 PM

#

study in school i guess

indigo needle Nov 6, 2025, 12:42 AM

#

hey guys update, FAT12 build is gonna be bult first

#

sorry earlier i said FAT12 was discontinued:)

indigo needle Nov 10, 2025, 5:12 PM

#

UPDATE

#

THE BOOTLOADER HAS PROGGRESSED TO THE SECOND STAGE

#

i planned for just a 512 byte bootloader

#

but now im moving 1.5 KB bootloader

#

which the second stage is a full KB

#

which is not alot, with todays standards.. but it will be a new refreshing stage after i suffered through 512 bytes

#

the first signs of life for the seond stage

#

indigo needle Nov 26, 2025, 2:06 AM

#

hey guys!

#

this project was abandoned for a bit

#

but i have returned

#

and i even made some reforms as better assembly and basic 16 bit C that will be important

#

so ive came back to this project:)

indigo needle Nov 26, 2025, 3:04 AM

#

right now, ive ditched protected mode, we are sticking to real mode

#

and i might run DOOM on this OS since it doesent really focus much on DOS, it mianly interacts with hardware itself

#

or ill port it

frank drift Nov 28, 2025, 7:29 PM

#

You cant

#

DOOM ran on a DOS extender

#

32bit

#

You cant port as well unless you wanna be another copy of DOS

#

also

#

70s?

#

do you know what era your talking about

#

actually I dont think the IBM PC's were made in the 70's

#

you're gonna have to invent a time machine and bring a IBM PC

indigo needle Nov 29, 2025, 2:23 AM

#

well, first of all

#

this is an 80s type of OS

#

not a 70s

#

and yes, i am planning to switch to protected mode, but my first attempt failed due to relying heavily on BIOS

#

but that will be fixed

#

and DOOM can be ported to my OS

#

as long as i provide the necessary APIs required for DOOM

#

such as file loading etc etc

#

and this is meant to be a temporary DOS

#

i might make an extension for the OS like windows 1.0

#

you had to boot MS DOS to run windows, and i think this goes up to 3.1

#

(correct me if im wrong)

frank drift Nov 29, 2025, 10:18 AM

#

indigo needle as long as i provide the necessary APIs required for DOOM

just make a container for DOS programs

#

DOS was extremely weird

#

and if you want programs to work natively

#

you'll have to create a lot of weird API's

#

some legacy garbage

#

and some just outright weird because at the time no one knew how to use the 80386 to its fullest

frank drift Nov 29, 2025, 10:20 AM

#

indigo needle such as file loading etc etc

also

#

you might have to switch to fat16 or fat32

#

DOOM was 2MB

#

thats an absolute pain and a waste of space on fat12

indigo needle Nov 30, 2025, 1:38 PM

#

frank drift thats an absolute pain and a waste of space on fat12

for now, im deciding that programs will be stored only in memory, we dont need specifically to make it reside in disk

frank drift Nov 30, 2025, 1:43 PM

#

thats even worse

#

also you cant really bring programs into memory

#

they need to reside on a disk

#

unless you hard code them

indigo needle Nov 30, 2025, 1:45 PM

#

even on BIOS read int 13h, if your gonna read from floppy, or anything, it cannot write floppy>internal storage, the only option available is writing to memory

frank drift Nov 30, 2025, 1:45 PM

#

what?

#

you can write to a floppy

#

int 13h,03h or int 13h,0Bh

indigo needle Nov 30, 2025, 1:46 PM

#

int 13h ah=2

#

thats for read

frank drift Nov 30, 2025, 1:46 PM

#

huh uh

#

I know that

indigo needle Nov 30, 2025, 1:46 PM

#

int 13h ah=3 is write

frank drift Nov 30, 2025, 1:46 PM

#

there you go

#

you can write to a floppy

indigo needle Nov 30, 2025, 1:47 PM

#

but mainly, reading from floppy has only the option to memory

frank drift Nov 30, 2025, 1:47 PM

#

yeah thats because it cant fit any where else

#

you cant fit a 512 byte sector on a register

#

your still reading from a floppy

#

the program still resides on a floppy

#

a floppy is a storage device

#

or a block device, whatever you wanna call it

frank drift Nov 30, 2025, 1:49 PM

#

indigo needle but mainly, reading from floppy has only the option to memory

also I am pretty sure thats with every storage device

#

they all dump it into RAM to take from RAM

indigo needle Nov 30, 2025, 1:49 PM

#

yes

#

int 13h can use any disk

frank drift Nov 30, 2025, 1:50 PM

#

no not really

indigo needle Nov 30, 2025, 1:50 PM

#

as long as you reference back

frank drift Nov 30, 2025, 1:50 PM

#

it was designed for diskettes

#

aka floppies

#

thats why it uses cylinder, head, sector

indigo needle Nov 30, 2025, 1:50 PM

#

actually HDD, floppy

frank drift Nov 30, 2025, 1:50 PM

#

or track, head, sector addressing

indigo needle Nov 30, 2025, 1:50 PM

#

im not sure about CD

frank drift Nov 30, 2025, 1:50 PM

#

indigo needle actually HDD, floppy

Nope

indigo needle Nov 30, 2025, 1:50 PM

#

because i dont use it

frank drift Nov 30, 2025, 1:50 PM

#

it emulates for HDD

#

check the IBM XT/AT system bios PDF

#

IBM never accounted for HDD's

#

it literally just emulates

frank drift Nov 30, 2025, 1:51 PM

#

indigo needle im not sure about CD

Think it has its own thing

indigo needle Nov 30, 2025, 1:51 PM

#

ah 42h?

#

extended read?

frank drift Nov 30, 2025, 1:51 PM

#

indigo needle ah 42h?

Doesn't exist on most bios

indigo needle Nov 30, 2025, 1:51 PM

#

i think CD uses it

frank drift Nov 30, 2025, 1:51 PM

#

it came too late

indigo needle Nov 30, 2025, 1:52 PM

#

actually in most modern BIOSes, there a chance for it to be tehre

frank drift Nov 30, 2025, 1:52 PM

#

CD was a thing LONG LONG before int 13h,42h was a thing

frank drift Nov 30, 2025, 1:52 PM

#

indigo needle actually in most modern BIOSes, there a chance for it to be tehre

yes

#

those are UEFI

#

UEFI with CSM

#

not a true IBM Bios

#

plus UEFI is starting to get rid of CSM

#

UEFI class 3

#

is an example

#

and intel is pushing it heavily

indigo needle Nov 30, 2025, 1:53 PM

#

personally, i think BIOS should be revived

#

BIOS is easier then UEFI for me

frank drift Nov 30, 2025, 1:53 PM

#

indigo needle personally, i think BIOS should be revived

Yes, but theres a reason it was replaced

#

it became duct tape on duct tape

#

every vendor did stuff differently

#

clones were all over the place

indigo needle Nov 30, 2025, 1:54 PM

#

yes

frank drift Nov 30, 2025, 1:54 PM

#

the IBM XT system bios was fairly clean

#

it was simple

#

and provided everything you needed

indigo needle Nov 30, 2025, 1:54 PM

#

well, i know some other UEFI will come out with different functions

frank drift Nov 30, 2025, 1:54 PM

#

and it matches its name "Basic I/O services"

frank drift Nov 30, 2025, 1:56 PM

#

indigo needle well, i know some other UEFI will come out with different functions

nope those are non standard

indigo needle Nov 30, 2025, 1:56 PM

#

you never know lol

#

there are still some UEFIs that are generally the same, but with extra useless functions we dont need

frank drift Nov 30, 2025, 1:57 PM

#

indigo needle you never know lol

No otherwise the point of UEFI would be ruined

indigo needle Nov 30, 2025, 1:58 PM

#

frank drift No otherwise the point of UEFI would be ruined

i guess

frank drift Nov 30, 2025, 8:21 PM

#

indigo needle i guess

Btw

#

if you wanna be for the 80s/90s

#

you can just assume floppy

#

everyone used floppies

#

they were the main thing

indigo needle Nov 30, 2025, 8:22 PM

#

frank drift you can just assume floppy

HDD existed in the 80s tho

frank drift Nov 30, 2025, 8:22 PM

#

yes but floppies were dominating

indigo needle Nov 30, 2025, 8:22 PM

#

they were 5-12 MB

frank drift Nov 30, 2025, 8:22 PM

#

Yep

#

but the average user didn't have a HDD

#

it wasn't cheap

#

no one wanted to spend more money on a larger "floppy" that they cant even swap out easily if it fails

indigo needle Nov 30, 2025, 8:23 PM

#

it was atleast for the rich people

frank drift Nov 30, 2025, 8:23 PM

#

also MS/PC-DOS and other operating systems were stupidly small and simple

#

they could run on anything

#

which is why clones were actually able to work

frank drift Nov 30, 2025, 8:24 PM

#

indigo needle it was atleast for the rich people

Yeah

#

it was

#

not even a joke

indigo needle Nov 30, 2025, 8:24 PM

#

so i might aswell add it

frank drift Nov 30, 2025, 8:24 PM

#

IBM system/360, AT&T bell lab's PDP

#

etc

#

used by big fat machines

#

I am pretty sure those fat machines didn't use the 8086/8088 tho

#

or anything X86 at that

frank drift Nov 30, 2025, 8:25 PM

#

indigo needle so i might aswell add it

you actually can

#

the bios emulates it

indigo needle Nov 30, 2025, 8:25 PM

#

those machines used industrial grade CPUs

frank drift Nov 30, 2025, 8:25 PM

#

you wont have to do much work

frank drift Nov 30, 2025, 8:26 PM

#

indigo needle those machines used industrial grade CPUs

yeah

#

They were insanely expensive

#

and got very hot

#

going up to a million USD at some point

#

mostly used by governments or colleges / uni's

indigo needle Nov 30, 2025, 8:27 PM

#

i agree

frank drift Nov 30, 2025, 8:28 PM

#

anyways you probably will support other drives without knowing

#

the BIOS emulated a lot of stuff

#

just dont try speaking directly to hardware controllers and your good to go

#

UEFI + CSM emulate USB's as super floppies

#

weird I know

indigo needle Nov 30, 2025, 8:29 PM

#

yup

frank drift Nov 30, 2025, 8:30 PM

#

Also you might wanna throw support for the IBM XT system bios out of the window

#

just use the IBM AT system bios

#

IBM XT system bios was simple, but very very tuned to what IBM wanted

indigo needle Nov 30, 2025, 8:31 PM

#

what if i release a seperate version for it?

frank drift Nov 30, 2025, 8:32 PM

#

indigo needle what if i release a seperate version for it?

Thats fine, but note that this version only support floppies

indigo needle Nov 30, 2025, 8:32 PM

#

its alright

frank drift Nov 30, 2025, 8:32 PM

#

because you're gonna have to talk to a hardware controller if you want to be a real OS

indigo needle Nov 30, 2025, 8:32 PM

#

my OS supports both tho

frank drift Nov 30, 2025, 8:32 PM

#

alright then just release another version for the IBM XT

#

I am just setting my baseline at IBM XT

#

8088 and IBM XT is my baseline

indigo needle Nov 30, 2025, 8:32 PM

#

how much people ahve an IBM XT?

#

have*

frank drift Nov 30, 2025, 8:33 PM

#

indigo needle how much people ahve an IBM XT?

It was cheap and mass produced

#

so probably still exists

#

but its also probably gate kept by retro nerds

indigo needle Nov 30, 2025, 8:33 PM

#

then im releasing a seperate version

frank drift Nov 30, 2025, 8:33 PM

#

like seriously cheap

#

IBM cut cost a lot

#

they didnt even wire some stuff

#

anything they didnt need

#

wasn't wired

#

just to cut cost

indigo needle Nov 30, 2025, 8:33 PM

#

2.1 million were produced

#

so im making a seperate version

frank drift Nov 30, 2025, 8:34 PM

#

you cant even tell when the floppy is ready for I/O operation because IBM didn't wire the pins

indigo needle Nov 30, 2025, 8:34 PM

#

oh

frank drift Nov 30, 2025, 8:34 PM

#

the IBM XT system bios would just wait the worst case

#

which was ~500ms

#

and assume the floppy was ready for I/O operation

#

like I said

indigo needle Nov 30, 2025, 8:34 PM

#

well that was unpractical..

frank drift Nov 30, 2025, 8:34 PM

#

stupidly simple

#

very dumb

#

and very cheap

#

IBM wanted cheap not advanced and not smart

indigo needle Nov 30, 2025, 8:35 PM

#

it would prob cost like an extra cent to include floppy ready or no

frank drift Nov 30, 2025, 8:35 PM

#

indigo needle it would prob cost like an extra cent to include floppy ready or no

yeah and IBM didnt want that

#

they wanted that extra cent for themselfs

indigo needle Nov 30, 2025, 8:35 PM

#

greed

frank drift Nov 30, 2025, 8:35 PM

#

Actually some higher end models did have it wired

indigo needle Nov 30, 2025, 8:35 PM

#

oh nice

frank drift Nov 30, 2025, 8:37 PM

#

You probably won't need to read the READY bit from the FDC tho

frank drift Nov 30, 2025, 8:39 PM

#

indigo needle oh nice

btw

#

when touching the floppy controller

indigo needle Nov 30, 2025, 8:39 PM

#

i do tho

frank drift Nov 30, 2025, 8:39 PM

#

you should check if it was wired by IBM

indigo needle Nov 30, 2025, 8:39 PM

#

?

#

oh

frank drift Nov 30, 2025, 8:39 PM

#

seriously

indigo needle Nov 30, 2025, 8:39 PM

#

well this is not a version for IBM

#

ill release it soon

#

and port it

#

plus

frank drift Nov 30, 2025, 8:40 PM

#

they didn't even wire the pins for DRIVE CHANGED

indigo needle Nov 30, 2025, 8:40 PM

#

im in real mode

#

so not needed

#

well thats greedy..

frank drift Nov 30, 2025, 8:40 PM

#

my OS has to brute force it

#

by checking the file system signature and a per drive special ID cached on RAM

#

and comparing it with the one on DISK

#

to detect if the drive was changed

#

you know sense you can swap floppies

#

in and out

#

with ease

#

alright it was nice talking to you

#

I gotta go

indigo needle Dec 1, 2025, 4:49 AM

#

yup

#

thanks

#

its nice talking to u too

feature*

#

like MS DOS and windows 1.0-NT

#

i think NT had MS DOS

join me guys in voice 1 if youd like to see the development of the IDT

past rose Dec 1, 2025, 7:36 PM

#

indigo needle like MS DOS and windows 1.0-NT

Windows 1.0-NT?

indigo needle Dec 1, 2025, 7:36 PM

#

i meant windows 1.0 to NT

past rose Dec 1, 2025, 7:37 PM

#

indigo needle i think NT had MS DOS

NT only had a DOS box for compatibility, i.e. NTVDM.

indigo needle Dec 1, 2025, 7:37 PM

#

im sure NT didnt have MS DOS tho..

#

oh

past rose Dec 1, 2025, 7:37 PM

#

the kernel has nothing to do with DOS

indigo needle Dec 1, 2025, 7:37 PM

#

the kernel of early windows booted from MS DOS

past rose Dec 1, 2025, 7:37 PM

#

yeah

#

but Windows NT is completely different

#

the NT kernel also basically has nothing to do with early Windows either

indigo needle Dec 1, 2025, 7:38 PM

#

XP was also built on NT and 9x

past rose Dec 1, 2025, 7:38 PM

#

mostly just NT

indigo needle Dec 1, 2025, 7:38 PM

#

some of the codebase was 9x tho

past rose Dec 1, 2025, 7:38 PM

#

which part?

indigo needle Dec 1, 2025, 7:38 PM

#

im not sure

#

it might be the games

#

or AOL

past rose Dec 1, 2025, 7:39 PM

#

AOL?

#

anyway, maybe some userspace utilities were brought over from 9x
but that's not really part of the core OS
a lot of the userspace codebase was already shared between NT and 9x since the mid to late 90s

#

Windows XP is essentially Windows NT in all ways that matter

#

like, I suppose Windows XP was the first NT version to have Windows Movie Maker

#

which was introduced with Windows ME

past rose Dec 1, 2025, 7:42 PM

#

indigo needle like MS DOS and windows 1.0-NT

also, NT never had any feature to go back to real mode

it can load from any DOS

AND HERES EACH PANIC SCREEN:

#

#

BLUE = NOT VERY SEVERE

#

PROGRAM ERROR OR A SMALL SYSTEM ERROR

#

#

YELLOW = MEDIUM SEVERITY

#

A MEDIUM ERROR IN A PROGRAM OR MEDIUM SEVERITY SYSTEM ERROR

#

#

BLACK = WORST SEVERITY

#

A BIG ERROR IN A PROGRAM, VIRUS, OR WORSE SYSTEM ERROR

#

CHANCE OF HARDWARE ISSUES.

THAT IS ALL PANIC ERRORS YOUD GET IN ILYODOS FOR NOW

so much wasted linear memory

indigo needle Dec 3, 2025, 4:22 PM

the stuff starting at 0x500 is supposed to be the important stuff as the FAT, the root directory entries, etc etc

bro

#

you do not need that MUCH memory

#

unless your going for multiple drive caching

indigo needle Dec 3, 2025, 4:22 PM

#

frank drift you do not need that MUCH memory

its also gonna hold the stack, the small programs, and more

frank drift Dec 3, 2025, 4:22 PM

#

which in that case yes you do

#

that adds up fast

#

if you cache fully for 2 fat12 floppies

#

you'll be using around ~20KiB or more worst case

#

actually probaably like ~30KiB

indigo needle Dec 3, 2025, 4:23 PM

#

with the kernel reaching just 64KB it would probably take just a little memory

frank drift Dec 3, 2025, 4:24 PM

#

64KiB?

#

thats

#

a fat kernel

#

for 32bit

#

at least

indigo needle Dec 3, 2025, 4:24 PM

#

oh

#

well its just a bit

frank drift Dec 3, 2025, 4:24 PM

#

also

indigo needle Dec 3, 2025, 4:24 PM

#

ill decrease it

frank drift Dec 3, 2025, 4:24 PM

#

now it wont run on the IBM XT

indigo needle Dec 3, 2025, 4:24 PM

#

when the kernels finished

#

theres a seperate version coming out soon

frank drift Dec 3, 2025, 4:24 PM

#

majority of IBM XT PC's have 64KiB of usable memory

#

dude

indigo needle Dec 3, 2025, 4:25 PM

#

this is the general PC (for 80386+) version

frank drift Dec 3, 2025, 4:25 PM

#

imagine trying to build apps for that

#

its gonna be weird

indigo needle Dec 3, 2025, 4:25 PM

#

welp

#

well

frank drift Dec 3, 2025, 4:25 PM

#

users will need to handle things differently for each OS

#

variant

indigo needle Dec 3, 2025, 4:25 PM

#

ill probably put them in an allocated memory

frank drift Dec 3, 2025, 4:25 PM

#

just do what DOS did

#

dont reserve for no reason

indigo needle Dec 3, 2025, 4:25 PM

#

prelalocated*

#

oh

#

alright

frank drift Dec 3, 2025, 4:26 PM

#

you can make an allocator

#

to cache stuff

#

much better

indigo needle Dec 3, 2025, 4:26 PM

#

i would probably not cache tho

frank drift Dec 3, 2025, 4:26 PM

#

sense the user can actually choose and you can tune it way easier for IBM XT or AT depending on what you want

#

or other computers on the 80386+

indigo needle Dec 3, 2025, 4:27 PM

#

general PC version is a minimum of 4 MB tho?

#

maybe less

#

not predicted yet

#

its in early development

#

but i say itd reach 2 MB

#

at worst case

#

4

frank drift Dec 3, 2025, 4:27 PM

#

Bro how

indigo needle Dec 3, 2025, 4:27 PM

#

making a 64KB kernel?

#

wait

frank drift Dec 3, 2025, 4:28 PM

#

I have an extremely simple and dumb custom C compiler that can easily be ported to my OS for the 8086 and floppy handling and etc

indigo needle Dec 3, 2025, 4:28 PM

#

frank drift Bro how

ill show you my plan

frank drift Dec 3, 2025, 4:28 PM

#

and I still dont get near to ~32KiB

indigo needle Dec 3, 2025, 4:28 PM

#

in the lower memory

#

meaning below 1 MB

#

theres s apce from 0x7e00 to 0x7FFFF

#

space*

#

its 480.5KB

#

if 64KB is allocated for the kernel

#

(may be reduced)

#

416.5 will remain

#

that could be used for programs, the shell

#

or the extended kernel

#

thatll be developped after the development of the main kernel is made

#

thats my plan

frank drift Dec 3, 2025, 4:31 PM

#

what do you intend to have?

#

you may have leaped too far in your size

indigo needle Dec 3, 2025, 5:24 PM

probably.. but im gonna reduce it once the kernels finished

so it prob wouldnt really work that well

frank drift Dec 8, 2025, 3:03 PM

#

What

#

1MB?

#

For what

#

What does bro have

#

Most 80386 OS's only need 200KiB and thats if there being evil

#

Minix ran with less than 1MB

#

and Minix had multi tasking and etc

#

educational OS as well

#

so not even professionally made

#

C compiler wasn't smart

#

meaning they didn't even try saving bytes

quiet shard Dec 8, 2025, 3:34 PM

#

is this writing for real hardware or just qemu

#

but either way, why is it in pure asm

#

what is the point

#

like genuinely

#

hell why are we even writing dos

frank drift Dec 8, 2025, 7:48 PM

#

quiet shard hell why are we even writing dos

DOS doesn't really mean MS-DOS or PC-DOS

#

although its referred to MS/PC-DOS normally

#

it could literally mean he is making a DISK OPERATING SYSTEM

#

thats all

#

You could call Linux, UNIX, Minix, windows a DOS if you wanted

#

it'd be weird but uhh its also kind of correct

frank drift Dec 8, 2025, 7:50 PM

#

quiet shard but either way, why is it in pure asm

That I dont know

#

A good reason would be C is annoying to deal with for the 8086/8088

#

but his OS is for the 80386+

#

which C runs extremely well on

#

without flaw

sir thats not literal

eternal ember Dec 9, 2025, 12:06 PM

never know with you

indigo needle Dec 9, 2025, 12:07 PM

you could lol

500 lines of asm without a singular comment 💔 🥀

eternal ember Dec 9, 2025, 12:09 PM

#

comments are evil

quiet shard Dec 9, 2025, 12:09 PM

#

i agree

#

@indigo needle make sure to not have any comments because they take up extra space on the disk

indigo needle Dec 9, 2025, 12:09 PM

#

well

#

thats my style:)

#

dont use comments

#

instead

#

i manually decode eac instruction

also

indigo needle Dec 9, 2025, 12:11 PM

#

quiet shard <@1109898717848420412> make sure to not have any comments because they take up e...

i use labels

#

to define sections of my code

#

guys

#

i use VSCODE for making my life a bit easier

#

and theres a problem with it not updating files that have been left in another editor before it ran??

#

how nice

#

UPDATE:

#

MANAGED TO GET LOOPS FOR KEYBOARD WORKING

#

AND VOTE:

#

MAKE THE DEVELOPERS DO EVERYTHING, AND MAKE IT HARDER FOR DEVELOPERS OR

#

MAKE INTERRUPTS AND MAKE IT EASIER FOR DEVELOPERS?

#

UPDATE AGAIN:

#

ADDING A CONFIG FILE FOR SETUP

#

HOW CONFIG SHOULD WORK:

#

CONFIG FILE WOULD BE 512 BYTES

#

FIRST BYTE WOULD INDICATE IF SETUP WAS FINISHED, IF SET TO 0, ITS NOT FINISHED (SETUP RESTART)

#

IF SET TO 1, SETUP FINISH (SETUP SKIP)

#

(by 0 and 1 i mean ASCII)

#

MINIMUM REQUIREMENTS ALSO CHANGED:

#

MINIMUM REQUIREMENTS FOR (MODERN PCs)

#

1 MB MINIMUM MEMORY

#

80386

#

AND FPU (NOT REQUIRED)

#

SET 2 KEYBOARD

#

THATS ALL

obsidian rampart Dec 9, 2025, 7:05 PM

#

indigo needle AND FPU (NOT REQUIRED)

fpu in kernel 😭

indigo needle Dec 9, 2025, 7:05 PM

#

thats just for programs

#

and not required

eternal ember Dec 9, 2025, 7:19 PM

#

use only floating point numbers

#

dont do any integer math

#

trl

white wren Dec 9, 2025, 7:56 PM

#

indigo needle 1 MB MINIMUM MEMORY

1 mb damn.

indigo needle Dec 9, 2025, 7:57 PM

#

white wren 1 mb damn.

im gonna add images so its prob gonna be 1 MB

#

images for the UI btw

white wren Dec 9, 2025, 8:02 PM

#

indigo needle im gonna add images so its prob gonna be 1 MB

ehmm AuroraOS at 10mb be like:

#

It needs atleast 20 mb to even run lol

indigo needle Dec 9, 2025, 8:02 PM

#

bru

#

wait what

#

currently

#

mine only needs like 10 KB

#

but considering all the UI and images

#

and future files

#

it might end up only at 1 MB

#

OR EVEN LESS

white wren Dec 9, 2025, 8:04 PM

#

indigo needle mine only needs like 10 KB

ehmm limine dosen't even boot at 10kb

#

flanterm throws out of mem error at 1M

indigo needle Dec 9, 2025, 8:04 PM

#

i only allocated like 30KB thats not used rn

#

for the kernel

white wren Dec 9, 2025, 8:04 PM

#

at 10 it gets all the way to FS

indigo needle Dec 9, 2025, 8:04 PM

#

my 512 byte MBR configures the FS..

white wren Dec 9, 2025, 8:04 PM

#

at 17 it can run (M)

indigo needle Dec 9, 2025, 8:05 PM

#

with FAT12

#

wait

#

if we do the math

#

lemme mdir my floppy image

indigo needle Dec 9, 2025, 8:09 PM

#

white wren at 17 it can run (M)

#

here it is

#

so

34816 bytes

wait

#

oops

34304 bytes is the total

that do the same thing

then two million functions to fill the screen with color n

obsidian rampart Dec 9, 2025, 8:33 PM

how do I buld this btw

frank drift Dec 9, 2025, 8:34 PM

#

obsidian rampart how do I buld this btw

Bro

#

just assemble using netwide

#

and write to image (or just format to the FS he's using and dump)

#

problem solved

#

check how the boot sector works first btw

obsidian rampart Dec 9, 2025, 8:35 PM

ugh it reads fat32

#

how to build this

ocean ocean Dec 9, 2025, 8:36 PM

@indigo needle also wym for 70s 80s machines

#

the IBM PC was released in 1981

#

Protected Mode came with the 386 only a few years later

indigo needle Dec 9, 2025, 8:36 PM

your right i need to change it

to 90s machines

#

cuz they have the requirements i need

frank drift Dec 9, 2025, 8:36 PM

#

Disable interrupts in the boot sector

ocean ocean Dec 9, 2025, 8:37 PM

#

be more specific also, indicate that it targets IBM PC compatibles

obsidian rampart Dec 9, 2025, 8:37 PM

#

how do I buld this btw

frank drift Dec 9, 2025, 8:37 PM

#

interrupts like messing with disk access

#

just clear them

ocean ocean Dec 9, 2025, 8:37 PM

and not my obscure ppc32elzbnmxf board that casually happens to have support for a 3000$ Amiga OS clone

white wren Dec 9, 2025, 8:37 PM

#

indigo needle 34304 bytes is the total

Crazy

#

Is it open source?

#

Like you were debating on making it closed source

indigo needle Dec 9, 2025, 8:38 PM

#

well the votes came

#

and i continued on open source

#

votes are votes🤷‍♂️

white wren Dec 9, 2025, 8:39 PM

democracy also allows me to say that the entire license is wrong, speaking of votes

indigo needle Dec 9, 2025, 8:40 PM

#

that was old OS name

#

changed it

#

it was NilOS

#

before

ocean ocean Dec 9, 2025, 8:40 PM

#

that's not the main problem

indigo needle Dec 9, 2025, 8:40 PM

alot of things changed

wait that was also the old license

Accessing, copying, decompiling or distributing any NilOS code [...] is strictly prohibited

#

mr tim sweeney ova here you uploaded the code for everyone to see?!?!?

indigo needle Dec 9, 2025, 8:41 PM

yall your voting this time on the new license:

not modifieble, or modifiable?

#

modifiable*

ocean ocean Dec 9, 2025, 8:43 PM

by jean valjean's ghost ask yourself a question give yourself an answer

indigo needle Dec 9, 2025, 8:43 PM

im bad at decisions

#

you choose

obsidian rampart Dec 9, 2025, 8:43 PM

#

indigo needle not modifieble, or modifiable?

no matter what licence you use it's NOT going to get modified

indigo needle Dec 9, 2025, 8:44 PM

#

because its in assembly?

obsidian rampart Dec 9, 2025, 8:44 PM

#

no

#

because it's 3 files

indigo needle Dec 9, 2025, 8:44 PM

#

oh

#

its in early phase

white wren Dec 9, 2025, 8:45 PM

#

Yea

indigo needle Dec 9, 2025, 8:45 PM

#

i dont know much about license so..

white wren Dec 9, 2025, 8:45 PM

#

It's a big mess too

white wren Dec 9, 2025, 8:45 PM

#

indigo needle i dont know much about license so..

Use MIT

indigo needle Dec 9, 2025, 8:46 PM

#

alright

#

MIT it is

white wren Dec 9, 2025, 8:46 PM

#

Simplest one out there

ocean ocean Dec 9, 2025, 8:46 PM

#

i'm used to GPLv2 but MIT is good too

indigo needle Dec 9, 2025, 8:46 PM

#

lemme just change it

#

changed

#

all is good now

#

you cant modify it, but its open source, and usable

eternal ember Dec 9, 2025, 8:56 PM

#

reverse-engineer source code ?

indigo needle Dec 9, 2025, 8:56 PM

#

is that in the new license?

eternal ember Dec 9, 2025, 8:56 PM

#

yes

#

you wrote it

#

how the fuck do you not know

obsidian rampart Dec 9, 2025, 8:57 PM

@indigo needle Im suing you for breaking the licence of ilyodos

#

indigo needle Dec 9, 2025, 8:57 PM

modified just some parts tho

obsidian rampart Dec 9, 2025, 8:57 PM

and yet your copy doesn't display this

#

im still making the new license..

#

im not good at licenses

obsidian rampart Dec 9, 2025, 8:57 PM

#

we can tell

#

just use bsd0 or bsd3 or mit

#

or gpl3 at this point

quiet shard Dec 9, 2025, 9:53 PM

#

so what happens if i violate this license

frank drift Dec 10, 2025, 7:26 AM

#

quiet shard so what happens if i violate this license

He can sue you

#

If it works properly that is

#

Other than that not much

indigo needle Dec 10, 2025, 9:50 AM

quiet shard so what happens if i violate this license

Passive aggresive letter, actually prob nothing at most

PERFECTED SET 1 KEYBOARD LAYOUT

indigo needle Dec 10, 2025, 4:40 PM

#

UPDATE:

#

#

where SETUP.BIN will reside

#

honestly i think this DOS wont be that big

#

the only files thatll take the disk space

#

are image files

#

and kernel BIN

white wren Dec 10, 2025, 4:48 PM

#

One question, why caps?

indigo needle Dec 10, 2025, 4:48 PM

#

i like caps plus its the default for my terminal

#

I LIKE CAPS VERY MUCH.

white wren Dec 10, 2025, 4:49 PM

#

indigo needle and kernel BIN

Why do you need your kernel.bin in your fs for?

indigo needle Dec 10, 2025, 4:49 PM

#

its the main kernel file

#

aka i will put almost everything in it

inland moth Dec 10, 2025, 4:49 PM

#

white wren Why do you need your kernel.bin in your fs for?

why do you need /boot

#

KEKW

white wren Dec 10, 2025, 4:49 PM

#

🙏

indigo needle Dec 10, 2025, 4:50 PM

#

inland moth <:KEKW:913708372329644042>

in my OS its called boot.asm, and its the MBR

#

my whole bootloader is the MBR:)

white wren Dec 10, 2025, 4:50 PM

#

inland moth why do you need /boot

I thought he had it in the ramdisk lol

inland moth Dec 10, 2025, 4:50 PM

#

indigo needle in my OS its called boot.asm, and its the MBR

rip so I can't boot your kernel on my pc

indigo needle Dec 10, 2025, 4:50 PM

#

not UEFI

#

this OS is BIOS

inland moth Dec 10, 2025, 4:51 PM

#

yeah i know

#

I can't boot it then

#

i have no CSM

indigo needle Dec 10, 2025, 4:51 PM

#

oh

#

umm

#

well i do use CSM for my whole PC

#

im using UEFI natively, but i boot everything on CSM

inland moth Dec 10, 2025, 4:52 PM

#

yeah my system just doesn't have it entirely

indigo needle Dec 10, 2025, 4:52 PM

#

my windows boots on CSM KEKW

#

honestly

#

i want BIOS to be revived

#

easier then UEFI.. in assembly

inland moth Dec 10, 2025, 4:53 PM

#

uefi is piss easy tho

obsidian rampart Dec 10, 2025, 4:53 PM

#

indigo needle easier then UEFI.. in assembly

hm better idea. ||not doing that at all||

inland moth Dec 10, 2025, 4:53 PM

#

and tbh I'm thankful for uefi

obsidian rampart Dec 10, 2025, 4:53 PM

#

embrace c

inland moth Dec 10, 2025, 4:53 PM

#

you can do uefi in asm

obsidian rampart Dec 10, 2025, 4:53 PM

#

inland moth you can do uefi in asm

idk why you would when you can use c

indigo needle Dec 10, 2025, 4:53 PM

#

im very thankful for the blessed soul who came to this mother earth and nurtured us with.. basic input output system..

inland moth Dec 10, 2025, 4:54 PM

#

uefi stands for ultimate bios replacement

indigo needle Dec 10, 2025, 4:54 PM

#

we need a petition to bring back BIOS

obsidian rampart Dec 10, 2025, 4:54 PM

#

the u in bios stands for "usable"

indigo needle Dec 10, 2025, 4:54 PM

#

oh

#

but theres no U

obsidian rampart Dec 10, 2025, 4:54 PM

#

exactly?

indigo needle Dec 10, 2025, 4:56 PM

both have different purposes

I guess but at the same time if you don't understand uefi you still have alot of learn

its my first actually becoming successful OS😭

#

am still learning

obsidian rampart Dec 10, 2025, 5:10 PM

well idk if rolling your own bootloader is a good learning experience tbh

indigo needle Dec 10, 2025, 5:10 PM

still good enough

obsidian rampart Dec 10, 2025, 5:10 PM

#

for some people maybe

like

i learned

that putting all ur code in a single file
