# rOSka
|
||||
Multiboot compatible stupid useless OS-like project that is literally trash.
|
||||
Multiboot compatible stupid useless OS-like project.
|
||||
## Compatibility
|
||||
- 32bit x86 compatible CPU required
|
||||
- Booting is done with a MultiBoot compatible bootloader (for example Grub)
|
||||
- Linear framebuffer graphics with 8bits per channel (any 8bit divisible
|
||||
bitdepth should work but is undefined behaviour, probably funny colours lol)
|
||||
- At some point tested with an old Pentium III (legacy BIOS) and a Ryzen 7 in
|
||||
EFI mode. Currently aiming to support both systems.
|
||||
- x86 system with MultiBoot compatible bootloader.
|
||||
- Linear framebuffer graphics
|
||||
## Building
|
||||
FASM is used as the assembler.
|
||||
TinyCCompiler is used, even for assembly lol.
|
||||
TCC might need manual compilation for 32bit crosscompilation
|
||||
on 64bit systems.
|
||||
Just download the source and `make cross` or something.
