Hi,

I'm writing a real mode os,with complete FAT12 support,
I'm using a floppy image
I also supported some DOS INTs,and every day I'm supporting more,
and I'm able to load and execute programs...
anyway my question would be,is it possible to port FASM for DOS
to my os?

Thanx.

Sure , in the fasm package there is a file called system.inc
adapt it to your os Wink

How up-to-date is it ?

It is ... but you need some file I/O (FASM is less demanding than LD Laughing) and 32-bit (use unreal or raw PM if your "OS" doesn't supply anything). Judging from your other thread, it might be a bit early for this task Wink

The interface functions have not changed since then.
