Operating System/1
==========================
-= About =-
Operating System/1 or OS/1 for short is a
simple 16-bit OS written in x86 assembly that runs
in huge unreal mode.
Version 6.0.0 removed some stuff, but most
importantly it added a functioning file system called
Low Performance File System (LPFS). It can handle files
up to 18KiB in size (36 512B sectors).
Pinboard has been removed from the base
system and will be available with other software on a
special disk called "OS/1 Utilities disk".

- 512KB of RAM
- any video card / display

but who cares?)

-= Compilation =-
To compile OS/1 you need the following:
- i386-elf build of GAS (GNU AS)
- i386-elf build of LD
- a *nix compliant environment
- an emulator (QEMU recommended)
- make
When you wish to compile run this command:
make -i clean && make
-= Running on real hardware =-
To be honest, I have no idea if this will run
on real hardware. If you have the time, do test
OS/1 6.0.0 on real hardware and tell me how it went.
