If the BIOS detects error 2C, 2E, or 30 (base 512K RAM error), 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. The BIOS also sends the bitmap to the
port-80 LED display. It first displays the checkpoint code, followed by a delay, the
high-order byte, another delay, and then the low order byte of the error. It repeats this
sequence continuously.
