Can anyone tell me what the POST codes 165 and 221 mean on an IBM PS2
P-70? The CMOS backup battery is good and I've tried to boot from the
reference disk but it won't load anything from the disk even though it does
read it briefly.

1. What OS you used to create this ref disk? Reason: If you "look"
at that disk after creation with exploder in win9x, ref disk sector
that all PS/2 post bios looks for is ruined. Solution: create that
disk again and at completion, eject NOW without even looking at it!
2. 165 is CMOS setting error, it needs set again with that ref disk.
3. 221 is memory error type problem. Might need to clear the CMOS
again then rerun ref disk. If not, motherboard needs to be replaced.
Which I happen to have one (for P70, 20MHz version) that works.
