Reserved Memory allows you to designate a region of system board memory that
can be supplied by an expansion card. You should not enable the reserved memory
feature unless you are using an expansion card that requires special addressing.
For example, you may have a memory expansion card that needs to be addressed
starting at 15 MB. Selecting the 15M - 16M
option in the Reserved Memory category
specifies that the base memory from 15 to 16 MB come from the memory expansion
card (the base memory below the 15-MB address comes from the dual in-line mem-
ory modules [DIMMs] on the system board).
