SOME CACHE MEMORY CONSIDERATIONS                                  TOP
================================================== Since single bank cache installations (B, D, F) prevent the cache sub-system from using interleaving access, the "Auto Configuration" in the Advanced Chipset Setup must be disabled and the "Cache Read Wait State" must also be set to "3-2-2-2" to ensure proper operation.

THE MAIN MEMORY                                                                                   TOP
==================================================
There are 4 banks of 72 pin SIMM sockets on this board with each bank of 72 pin SIMM consisting of only one SIMM socket. The system board has auto-detection circuitry to sense which bank or banks are filled. Fill any SIMM module in the configurations listed below with Fast Page Mode, single or double sided memory.

SOME MAIN MEMORY CONSIDERATIONS                                      TOP
================================================== •Maximum memory on-board can not exceed 256 MB in any
 combination.
•The memory installed in banks 0 & 1 must be more than or equal to
 the memory installed in banks 2 & 3.
•If both of the SIMM sockets in any single group (i.e. banks 0 & 1)
 are filled then both of the SIMM modules must be of the same type. •However, you do not have to fill up a single group with SIMM
 modules before starting on the next. See below for more clarification
 on these considerations.
