I use FreeDOS kernel 2038pre, FreeCom 0.84-pre2 as shell (although
4DOS is better but more complex), JEMMEX (XMS + EMS), UIDE (although
LBACACHE is good too and can unload), IDLEDPMS (from FDAPM), and
CWSDPMI r5 2008 for almost all DJGPP apps (although HDPMI32 is very
good too) and HXRT (which includes HDPMI32). You obviously also want a
decent editor (GNU Emacs? VIM? TDE? JED?) and CTMOUSE 2.1beta4. (I
don't really recommend DOSLFN, but some people swear by it.)

Seal (quite unstable) did some, but most didn't. However, PCOS sounds
interesting at least.

For threading, you'll have to use LWP or CLWP or adapt v1's AETSK. Or
you can use (buggy?) GNU pth (/current/ only !!) or FSU Pthreads
(highly unlikely).

FSU Pthreads precompiled)

Multitasking? No, not unless you want to risk TriDOS (and that doesn't
work with DJGPP v2 / DPMI anyways, but XMS is supported). I've heard
it can cause data loss, so caveat emptor. (But hey, if you're just
screwing around, it might be worth looking at.) Otherwise, you're
gonna have to do it the "hard way" (just being silly, I don't expect
you to actually do this)!   :-)

If you like VB, you may wish to check out FreeBASIC (which uses
DJGPP's C lib and can intermix with it).

Make sure to consider trying the latest QEMU 0.10.0 for faster speeds:

Hopefully that's MS-DOS 7.x since I consider FreeDOS better than 6.22
in 90% of everything (e.g. FAT32).
