Perverted DOS idea

Cameron: There are several sources for this info. Look for Ralf Brown. He made an "interrupt list" which is just a list of *all* interrupts. Mike Podanofsky wrote RxDOS, a DOS clone for the book "Dissecting DOS" from Addison-Wellsley. His company is API Software in New Hampshire. Try http://www.freedos.org/files/distributions/rxdos/ for a code distribution. The documentation and comments are excellent. -----Original Message----- From: Cameron Kaiser [mailto:ckaiser@oa.ptloma.edu] Sent: Thursday, June 08, 2000 12:17 PM To: classiccmp(a)classiccmp.org Subject: Re: Perverted DOS idea ::> How little memory could you run something like, say, DOS 3.3 in?

That was the thing I was worried about. Maybe I'll write Command.com natively instead. Someone suggested emulation from disk, and that's exactly how I was thinking of doing it. Where can I find a list of INTs DOS uses? I checked a couple of bookstores but most of them aren't too helpful with low-level DOS. -- ----------------------------- personal page: http://www.armory.com/~spectre/ -- Cameron Kaiser * Point Loma Nazarene University * ckaiser(a)ptloma.edu -- UBAX vs lbh ybir EBG-13 ----------------------------------------------------
