Notes
The board supports parity (x 36) or non-parity (x32) SIMMs.
Your system ships with non-parity SIMMs. Error checking
and correction (ECC) is supported with parity SIMMs.
There is no ECC with non-parity SIMMs.
All SIMMs must be tin lead, 72-pin, with 60 ns fast page-
mode DRAMs.
All SIMM socket sites must contain the same size SIMMs.
