(2C)RAM failure on address xxxx.If the BIOS detects error 2C,2E,or 30(base 512K
RAM error),it displays and additional word-bitmap(xxxx)indication the
address line
or bits that failed. For example, “2C 0002”means addressline 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 hav
e
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-
