Are you sure you have the mouse and keyboard plugged in their correct
jacks?

Being colour-coded, correct PS/2 jacks are easily verified
(KB purple, mouse green, but mine is actually a USB mouse.)

M52 now boots OK with extra RAM (total 3 Gb)
but with two delays:
Error 0164 memory size

This error message sounds like a setting in CMOS is incorrect. Enter
CMOS right after turning power on. There is normally a message on the
screen telling you how to do this. Normally it requires hitting a key
such as DELETE, ESC, or one of the function keys. Once in there save
the settings and exit. It might solve your problem.
Error .61 Media test failure; check cable.
and then boots OK. Can I bypass these by some
BIOS adjustment?
