2.3 Main Memory
The AI5TV provides two 64-bit memory banks for up to 128MB. Each
bank consist of two SIMM sockets, M0/M1 and M2/M3. Both EDO
and page mode DRAMs are supported. The size of the SIMMs can be
4MB, 8MB, 16MB or 32MB.
Each 64-bit memory bank can also be populated by using a DIMM
(Dual In-line Memory Module). The DIMM size can be 8mb, 16MB,
32MB or 64MB. The DIMM types can be FPM, EDO or SDRAM
(synchronous DRAM). Since SIMMs are not available in SDRAM,
DIMMs must be used for SDRAM support.
The following are the important factors for populating the SIMM
sockets:
1. Either M0/M1 or M2/M3 bank can be populated first
2. Each bank should consist of the same size SIMMs
3. Each bank should consist of the same type SIMMs.
ex: M0 and M1 should both be EDO or page mode.
4. SIMMs can be mixed by the bank.
ex: M0/M1 are page mode and M2/M3 are EDO
5. If M2/M3 are occupied, then M5 can not be populated. The reverse
is also true.

Note: Bank0 designates the memory bank populated first which
can be M0/M1 or M2/M3.
