(From steps 012 and 015)
– Power off the system unit.
– An expansion box memory failure indicates a failing channel memory card.
– A 230 POST error indicates a channel memory overlapping problem.
Remove the channel memory card from the riser card and continue.
– A 225 error indicates a SIMM is not supported by the system board
(386SX system boards only).
– 486SX and 486DX (30-pin memory SIMM) system boards:
Verify the SIMMs in each bank are the same value SIMMs. If there are
eight SIMMs installed, remove the four cards from bank 1. If you have
four SIMMs installed, they should be in bank 0.
– 486SX, 486DX, and 486DX2 (72-pin memory SIMM) system boards:
Any SIMM can be positioned in any location. The SIMM sockets (banks)
are numbered 0, 1, 2, and 3 starting from the outer edge of the system
board.
– Insert the Advanced Diagnostics diskette into drive A.
– Power on the system unit.
