Reset Configuration Data
Use this setting to clear CMOS (by selecting “Yes” and
rebooting) if the system parameters get corrupted. The
default is “No.”
Memory Cache
Memory cache saves time for the CPU by holding data most
recently accessed in regular memory (dynamic RAM or
DRAM) in a special storage area of static RAM (SRAM),
which is faster. Before accessing regular memory, the CPU
first accesses the cache. If it does not find the data it is
looking for, it accesses the regular memory.
The default for the Memory Cache is “Enabled.” This field
controls both the primary and secondary caches. Setting the
Memory Cache to “Disabled” will hurt performance, but
might be required when running programs that utilize
software-timing loops and need to be slowed down to
execute properly.
Memory Banks 0 and 1
The two Memory Bank fields are read only. They display
the total amount of memory in each DIMM bank.

Memory Reservation
Use this field to reserve specified blocks of upper
memory for use by other ISA devices. Select “Reserved”
to choose a memory block. The default for each block is
“Available.”
