    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.

According to my references:

221 is a ROM to RAM parity error on the System board. Has someone perhaps
put non-parity SIMMs in that P70?

165 is a Configuration error. Try setting the date and time and running the
System autoconfiguration.

I would try putting known good parity SIMMs in the P70 and then try to run
the Reference and Diagnostics disks again.

Cheers,
Mark.
