A couple of months ago, I removed my P133 from my socket 7 Endeavour board
and sold the CPU. I decided to wait for the P166 to come down in price.
About 5 weeks ago, I needed something off one of the Panasonic PD optical
disks, so rather than removing the drive completely, I powered it the system
up and ran the ribbon cable to the PD system from the other machine I was
using.

Today, I've put a P100 back into the Endeavour and when powered up I get 
nothing on the screen, and just one beep round about the time one would
expect it to finish the POST.

The CPU checks out ok on another EV board with all the RAM etc moved over,
so the problem is down to the board.

The only thing that is odd is that it does try to access the floppy, and
after the first seek it goes into a frantic sek mode,

Can someone suggest (helpfully) what may be wrong, and what I can do about
it? Has the flash ROM become corrupt or something?
