3.2.4 Installing SIMM Upgrades
The NBR allows memory upgrades for FLASH Electrically Erasable
Programmable Read only Memory (FLASH EEPROM), Shared Dynamic
Random Access Memory (SDRAM), and Local Dynamic Random Access
Memory (LDRAM). This section explains how to locate and add or
replace a Single In-line Memory Module (SIMM) for any of these
memory types.
Each memory type has a specific SIMM slot location on the NBR
motherboard. See Figure 3-2 for SIMM slot location. When installing
SIMM boards, make sure that you place them in their proper slots.
