After extensive repair of a motherboard with a lot of damage it came back to life, kind of.
AMI BIOS beeps 8 times - graphics card related error code.
Voltage on ISA pin B05 should be -5V, but is +1.9V. Suspicious. Unable to figure out where this discrepancy comes from.
Hesitant to just connect it to -5V line.
Any opinion on the issue ?
