POST Routine Description
* If the BIOS detects error 2C or 2E, it displays an additional word-bitmap (xxxx) indicating
the address line or bits that failed. For example, “2C 0002” means address line 1 (bit one
set) has failed. “2E 1020” means data bits 12 and 5 (bits 12 and 5 set) have failed in the
lower 16 bits.
