I followed Intel's instructions for using recovery mode (jumper change)with the BIOS upgrade disk. Everything went okay, got the 2 beeps, etc. as described.
After moving the jumper back to "normal" the system comes on, but won't boot. No floppy or video, nothing. Found one resource that suggests this is a symptom of a bad user data area or "ESCD block." But the BIOS recovery has had no effect.
Did I fry my motherboard? HELP!
