I am considering buying the 80x86 version of Minix and wondered: Has anyone been able to get a MS-DOS application to run under a COMMAND.COM process under Minix? I assume this is possible because commercial 80x86 Unix versions allow this. Would this be a huge undertaking or within the capability of a casual programmer? Minix sounds like a great vehicle to learn operating system theory, and I thought this would be a good project. Am I dreaming??? -- Kevin Routh (routh@rtp.semi.harris.com) Harris Corporation, Durham, NC (919) 361-1622

You'd have to write a process and a task that puts the 386 in V86 mode. If you have the bucks, you might be able to license VP/ix from ISC, but they won't let you publish the source. :) // JCA /* **--------------------------------------------------------------------------* ** Flames : /dev/null | What to buy? ** ARPANET : crash!pnet01!jca@nosc.mil | EISA or MCA? ** INTERNET: jca@pnet01.cts.com | When will the bus wars end? ** UUCP : {nosc ucsd hplabs!hp-sdd}!crash!pnet01!jca **--------------------------------------------------------------------------* */

I've used VP/IX on a sun386i and was somewhat happy most of the time. They do lots of "magic" into the kernel to flip around the 386 chip (which isn't documentented). I think a good portable Ms-Dos emulator in C would be much more useful. Also I heard gcc runs for Ms/Dos (haven't yet seen it). I basically don't like vendors who hide source code (I agree with rms -- source code is knowledge -- how many people can do useful things with source code besides wizards?) marty (Knowledge is useful in the Information Age) (I hate slow, non-intuitive non-creative computer systems) ARPA: leisner.wbst139@xerox.com NS: leisner:wbst139:xerox UUCP: hplabs!arisia!leisner

But we do have a plan on something alike, but we won't be implementing it until we receive MINIX 1.5 from P-H. Here I apologize to all who have been waiting for information from me, I didn't expect this many requests (~30) for NYUMINIX (this is what we call it), and the requests come from all over the world, so I had to add back (what I removed for optimizing reason) the conditional compilations and DUTCH keyboard portion, to reduce the size of the diff list. My next posting will be a guide for those who already have MINIX 1.3 (running or sitting in the box) to make the necessary modification. If you don't have 1.3, I'm afraid that I can't help due to the copyright restriction on the source. Benchiao Jai jai@cs.nyu.edu
