486-VIP-IO Item: 8MB SIMMS issue Based on the Manual, VIP IO motherboard can only support either 1MB, 4MB or 16MB each socket. It did not mention 8MB. Maybe there were some issue on that otherwise it was included on it. Please try to use 4MB and put it on four slots to produce 16MB or perhaps just one piece 16MB on one slot. That's the only DRAM configuration on the manual.
