If the BIOS detects error 2C, 2E, or 30 (base 64K RAM error), it displays
an additional word of information reflecting the bit or address line that
failed. For example, if "2C 0002" is displayed, address line 1
(represented by bit one) has failed. If "2E 1020" is displayed, then data
bits 12 and 5 have failed in the upper 16 bits.
The BIOS sends the same information to the port 80h LED display. The
check point code is followed by a delay, the high order byte, another
delay, and then the low order byte of the error. This is be repeated
continuously.
