   I have been trying to get MINIX 1.2 to run on a PS/2 Model 25
   with a 720KB 3.5" Diskette drive.  I seem to be getting the     
   same problems people are have on the Model 50 even though
   model 25 uses an 8086 and 720KB drive (not 1.44) and no
   microchannels ( as far as I know).  I think 
   The problem is in floppy.c because the DMA of the Boot diskette
   works fine in the case of a warm as well as a cold boot.  Once I
   get the initial menu and type '=', one of two things happen:
   1.  The system hangs up with no explanation.
   2.  The system writes the message that a trap < 16 occured then
       hangs up.
   
   Since noone on this newsgroup have mentioned anything about    
   model 25, my two questions are:

   1.  Has anyone tried to run minix on a PS/2 model 25, and if so
       has anyone got it to work or at least got the same problem?

   2.  Am I heading in the right direction with the problem?  I was
       planning to do some work with floppy.c and recompile the kernel
       and build a new diskette but since I have to do this on a PC then
       DOS copy the diskettes onto 3.5", this could take me several hours
       before I can run home and try it on my PS/2.  Does anyone have
       any seggestions on what to do???

   Any information will be greatly appreciated.
