- The only problem with the MCA is in the HD interface.
- The situation is
- 1) CMOS ram on a PS/2 contains no info on HD's, thus the code to check
- the HD's simply dosn't get run.
- The info in the BIOS (and maybe from the controller) is correct about
- the HD geometry.
- (in fact the Microsoft diagnostic program MSD appears to be confused
- by the geometry of PS/2 HD's)
- 2) PS/2's have a 6 (or maybe 8) bit register for number of heads on the
- HD, AT bus machines only have a 4 bit register for this.
- (some PS/2's claim to have 64 disc heads, it is the controller which
- sorts out this fudge)
- 3) Documentation to find out exactly what is going on is hard to come
- by....
-
- 4) Untill I can find some way to cross build a kernal (with lots of
- printk's added) I havn't got a clue as to how to get this to work...
-
- Other than that FD's memory management printer and just about everything
- else work fine.
-
- I posted to comp.pc.hardware.ps2, but got no response.
