Thanks - I will take a look.

The good news is that my BIOS supports "Start at power on".
However the BIOS is also part of the problem.
This is a ASUS motherboard with C.P.R (CPU parameter recall)
Basically if the CPU does not survive a BIOS startup it will drop into
"safe mode" and present a menu to change the CPU setting.
Unfortunately power flickers seem to perfectly emulate wrong CPU
settings and the machine just hangs there in the BIOS setup screen :-(

The good old times ;-)
Nowadays you need $$$$$/per year software just to figure out the signal
waveform/delay from pin A to pin B. (at least for the things that I
would like to play with)
