RAM error),it displays and additional word-bitmap(xxxx)indication 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 the port-80 LED display. It first
display 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. Test 512 base address lines.(Beep)= 1-3-4-1 Activate interleave(if
