Hi Basil

Bob & Ricksorry didn't read your post until it was too late!:-(
Sorry I could have been a little clearer in my last post.
I kept pressing F2 as it booted and got the light blue error screen about a
configuration error. It then went onto give the same configuration screen
as doing it the right way by pressing F1.
I sadly report this morning it died with one long continuous beep which the
manual says is either the power supply or the planar.
Now on start up there is deathly silence except for the power supply fan and
case fan going. Measured the output leads on the power supply ( that deadly
Delta brand ) and all are okay, so I guess I have a dead planar.
Completely dissassembled the machine to be sure no screw etc it under the
planar and reassembled it piece by piece, testing along the way as Peter
Norton suggests in his book.
Could not get a squeak out of the machine.
Was talking to the guy at the computer shop and he seems to think you hit F7
or F9 at the blue IBM logo screen to get into the bios, but I of course
cannot test that now.

I have 2 of those machines, the short and the high desktop version, you
can only go up to 100mhz per spec, usually the pinss configuration is
written on the case on the inside,
one thing for sure they seems to die silently, can't remember quiet well
but I think the Dallas ?? or the coin battery has something to do with
it, worth a try.
yes you get into the bios by holding F1 only during cold boot (when you
turn the machine on for the first time)
I might still have a spare mobo somewhere, let me know if you decide to
revive it again, I might also have a spare PSU.
for the record they use 5volts 72pins edo ram.

The battery status is certainly worth checking out. I recall that a dead
CMOS backup battery could seize up a few rare computers of this vintage.
And other possible problems that can create an error condition - like a
loose keyboard cable. I remember working with a crAptiva of this vintage
- a pentium 200 - and certain things would cause the system to not boot,
and not produce a BIOS post error either. That system would sit there
hung if the keyboard cable was loose or unplugged. No video, no POST
beeps - all you would get is the power on LED on the front panel until
the keyboard was plugged in and the system was happy with the
connection. Weird for any computer, but hey! - we didn't call it a
crAptiva for nothing. There was some strange stuff going on in IBM
BIOS's in this period.
