Memory Expansion Module Installation
The XVME-956/101 Memory Expansion Module (MEM) is an embedded
system module which provides a convenient means to expand your Xycom
VME AT system. The XVME-956/101 MEM four byte-wide memory sock-
ets are organized into two groups of two sockets each. Each group can be
configured for a different type of memory device, allowing many possible
memory configurations. All of the 32 to 512 Kbyte static RAMs, as well as
many types of Flash EPROMs are supported.
This chapter describes how to configure and install the memory expansion
module. Before using the memory expansion module, install the memory
devices and verify the jumper settings.
