Where nnnn is the amount of RAM in kilobytes successfully tested.
Failing Bits: nnnn* The hex number nnnn is a map of the bits at the RAM address (in
System, Extended, or Shadow memory) which failed the memory test.
Each 1 (one) in the map indicates a failed bit.
Fixed Disk 0 Failure

values and they are not corrected, the next boot will likely fail. On
systems with control of wait states, improper Setup settings can also
terminate POST and cause this error on the next boot. Run Setup and
verify that the wait-state configuration is correct. This error is cleared
the next time the system is booted.
