MS DOS

Tue Mar 25, 2014 11:38 pm

Is there any value in trying to get MSDOS running on a RPi?

Getting as in porting??

Probably not since you could image an MS DOS boot diskette and fire up Qemu instead. :)

No point other than self-satisfaction.

The source released is for MS-DOS 1.1 and 2.0. Really rubbish versions. I haven't looked at the code (which has various restrictions on its usage), but I'm guessing it is in 8086 assembler, which would be fun to convert - and, yes, I have done that with quite a lot of code in the past.

It would also rely heavily on a PC style BIOS with all the INT features to access keyboard and stuff, so you'd have to emulate that too.

I like the PC emulator on my original Acorn Archimedes the had a BIOS image floppy and would run MS-DOS 3.3, which running at 4MHz would sometimes be faster than a genuine PC running at 4.77MHz (even better when I got more memory, added a 105MB hard disk and upgraded to ARM3 at 20MHz(?))

I was thinking the same. MSDOS is ancient at best and it's only use is as a Piece of history. If anything, we could look at FreeDOS.
