Repeat failed test to help diag hardware issues

Closed this issue · 0 comments

When an error condition happens the bios will normally print an error then go into a loop waiting for the user to reboot.

With certain error conditions it would be useful for the bios to also continually repeat the error condition to allow tracking down the hardware issue. For example if you got a ram WE error, have it continually write ram so you can use a logic probe to see where the WE issue might be coming from.
