Case 2 – After removing any existing SIMM(s),
two SIMMs are to be installed, at least one of
which is a double-sided SIMM (see figure B-1.2).
two SIMMs are to be installed, at least one of
which is a double-sided SIMM (see figure B-1.2).
In this configuration, the double-sided SIMM board
must be installed into slot 1. This is regardless of
respective memory sizes of the SIMM boards – the
double-sided board always goes into slot 1. If both
SIMMs are double-sided, it does not matter which
one goes into which slot.

Case 3 – After removing any existing SIMM(s),
two single-sided SIMMs are to be installed (see
figures B-1.1).
two single-sided SIMMs are to be installed (see
figures B-1.1).
This configuration could occur if, for example, you
wanted to simply add a second SIMM to the
controller’s factory-shipped configuration. In this
case, the single-sided SIMM to be installed into slot 2
must have a PD jumper installed.

Unsupported Memory Configurations
Memory configurations not listed under the rules
above are not supported, or will not yield the correct
amount of memory for the controller. This includes
any combination of boards which:
above are not supported, or will not yield the correct
amount of memory for the controller. This includes
any combination of boards which:
1) Does not yield the minimum amount of memory
needed by the controller.
2) Utilizes 1 or 2 Mbyte SIMMs.
3) Utilizes a single-sided SIMM in slot 2 that does
not have a PD jumper installed.
If you believe your memory configuration is
supported, but it is not yielding the correct amount of
memory, see the section on Troubleshooting a
Memory Upgrade located at the end of this Appendix.
