Memory type selection jumper
The 64-bit memory subsystem supports two types of 32-bit SIMM modules, EDO mode DRAM and Fast Page
mode DRAM (standard DRAM). These types of RAM can be used at the same time, but not in the same memory
bank. EDO DRAM can be used in BANK 0 and Fast Page DRAM in BANK 1 or vice versa, but not mixed in the
same bank. To full fill the 64-bit data bus width, SIMM modules must be installed in pairs. Jumpers for memory
type must be always set according to the installed SIMM type.
