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. Note that error 30
cannot occur on 386SX systems because they have a 16 rather than 32-bit bus. The BIOS also sends the bitmap to
theport-80 LED display. It first displays the check point 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.
