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 highorder byte, another delay, and then the low order byte of the error. It repeats this sequence continuously. Chapter 9 85
