5-32 Chapter 5, Error Messages and Codes

Memory error codes in the following tables are in the format:

Xx000Y ZZ 201

Failed data bit. Values are: 00, 01, 02, 04, 08, 10, 20, 40, 80. 00 = parity bit

01 = data bit 0

02 = data bit 1

04 = data bit 2

08 = data bit 3

10 = data bit 4

20 = data bit 5

40 = data bit 6

80 = data bit 7

Failed byte. Values are 0, 1, 2, 3. Always zero.

Ignore.

Failed address. Values are 0 through F. They indicate soldered memory or socketed memory and whether the board is the 32-bit system memory board, the 1- to 2-megabyte 32-bit memory board, or the 4- to 8-mega- byte 32-bit memory board.

0 or F*	= soldered on the 32-bit system memory board
1	= socketed on the 32-bit system memory board
2*	= soldered on the 1- to 2-megabyte 32-bit memory board

3= socketed on the 1- to 2-megabyte 32-bit memory board

2thru 5* = soldered on the 4- to 8-megabyte 32-bit memory board

6thru 9 = socketed on the 4- to 8-megabyte 32-bit memory board

*If error indicates a soldered chip), replace the board.

After identifying X, use Figures 5-1, 5-2, and 5-3 to identify the location of the bad data bit.
