Ok guys, bad news.
Nothing happens.. tried the following:
Booting without memory, with 68040 ON: Black screen
Booting without memory, with 68040 OFF: Works normal, but PPS software doesn't 'see' the card (get the 'You need a progressive card' message)
Booting with memory (8mb), with 68040 OFF: Black, then Gray, then Yellow screen with Power led blinking 10 times, and reboots again to black, gray and yellow. Can't reboot by keyboard.
After a while watching the color cycling on the screen, I got a 'SOFTWARE ERROR - CLICK LEFT BUTTON' and then a (not very informative?) screen.
I'm attaching it.
Btw, I checked and double checked jumper settings, it's ok.
Thanks!
Seems like a memory error, I got this too from a failing BSC AT 2008.
Try taking out all the memory and then insert one of them and each time add one, just hope they are not all dead.
