I finally got ready my contribution to SWAG. I hope it will be
included in the August release :)
It consists of some software / hardware detection (pci boards, vesa
compliant cards, fpu, game port, xms, emm, 4dos, etc.)
Put it in the section that you think it's more appropiate. I think
HARDWARE would be nice (although it has some software routines) or maybe
MISC. I don't know. It's up to you :)
Anyway, I suppose you will include the appropiate keywords, won't you?
Well, here it is. Maybe I have time to send you some other
contributions for the August release.

Well, that's all for today ;-). I have some other routines but I
didn't include them because they were so messy. I am also interested on
seing your routines :). A lot of this things can be easily taken out from
the famous Ralph Brown Interrupt List.
Feel free to contact me for commentaries, questions, enhancements
or whatever.
