RAM Configuration
192 MB Maximum. Six 36-bit SIMM sockets. Minimum system configuration = 16
MB. 32 MB SIMMs are industry standard and are not the same as those used in the
XEN-LS II/PC.
Memory is configured as 64 bit wide, thus SIMMs must be installed in
identical pairs, e.g. 16 MB = 2x 8 MB SIMMs.
Pentium CPU Board
RAM Configuration
256 MB Maximum. Eight 36-bit SIMM sockets. Minimum system configuration =
16 MB. 32 MB SIMMs are industry standard and are not the same as those used in
the XEN-LS II/PC.
Memory is configured as 128 bit wide, thus SIMMs must be installed in two
groups of four, as follows:
MM1, 3, 5, 7
MM2, 4, 6, 8
e.g. 16 MB = 4x 4 MB SIMMs
