1.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 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.
