I've just tried to get MINIX running on an IBM PS/2 Model 70 386, and found that the ps_wini.c driver only works for ST506 drives. The Model 70 has a strange drive on an edge connector rather than ribbon cables - I presume that it is some kind of IDE, but I wouldn't like to bet on it. Has anyone got MINIX running on one of these machines ? I don't want to use bios_wini.c because I want to run Bruce's 386 version of MINIX and I assume that anything which calls the BIOS is strictly verboten for this.

The PS/2 Model 70 386 actually uses an ESDI controller that is identical in function to the ESDI adapter that you find in a standard slot on other PS/2s. They used the basic idea behind IDE drives (i.e. controller built into the drive unit) to save a slot. From a software point of view, however, the configuration is almost identical to a normal ESDI configuration. The one small difference that I have noticed is that the adapter ID value that comes from the POS port on the PS/2 motherboard is different. Someone posted an ESDI driver a few months ago. It should work fine, unless it scans the POS registers in search of a particular adapter ID. If this problem does arise, the fix is pretty straightforward - just check for either of two adapter IDs.

Can any one verify that this is indeed a restriction of Minix 386? -- BURNS,JIM (returned student) Georgia Institute of Technology, 30178 Georgia Tech Station, Atlanta Georgia, 30332 | Internet: gt0178a@prism.gatech.edu uucp: ...!{decvax,hplabs,ncar,purdue,rutgers}!gatech!prism!gt0178a
