So DOS is still used by some?

Last time I used DOS, 6 years ago, I was using
something called WDOSX with NASM which made it
easy to make full use of the PCs memory and the
32 bit instruction set. I don't know if it
would work with FASM?

The other problem I had with DOS was the lack of
a decent explanation or full working example of
using VESA to access the higher resolution and
high colour screen modes.

Hi,Casey:
Please see below web link:
http://board.flatassembler.net/topic.php?t=4021

We can combine fasm and djgpp (Ver2.03) together. So you access 4G memory on DOS platform and you can use all of C library on djgpp. Of course, you can use allegro graphics library supported VESA driver.

Probably flat binary but not via RDOFF. Anyways, WDOSX doesn't support NASM 0.98.39's latest variant of RDOFF 2 (but NASM 0.98, DJGPP version, seems to work). Also, NASM 0.97 works too (RDOFF 1). Strangely enough, NASM 0.98 (DJGPP) has both -rdf (older RDF 2) and -oldrdf (RDF 1.1) switches. I don't think WDOSX is supported by its author anymore. At least sources are included!

VC2003 with PE output (remember the linker switch /fixed:no) + WDOSX. Nice combination.

Fasm and wdosx work well together, just tell fasm to output PE format, but keep in mind that wdosx is a bit picky with the PE files it can use, you may have to increase heap space and always add a fixup section.
