PS/2 Mouse

When disabled, this option prevents an installed PS/2 mouse from functioning, and releases IRQ
12. Set this parameter to Auto-Detect (default) to allow the system to determine whether or not to
enable or disable the mouse.

System Memory

This option displays the amount of memory in the system. This option is not user-configurable.

Extended Memory

This option displays the amount of extended memory in the system. This option is not user-
configurable.

Memory Cache

This option configures the state of the P6 memory cache. Enabling cache saves CPU time and can
improve performance by storing the most recently accessed data in a special storage area of static
RAM (SRAM). Before accessing regular memory, the CPU first accesses the cache. Select this
option and press enter to display the Memory Cache submenu:

Write Back (caches data and writes it to memory), Write Through (writes data immediately to
memory), or Write Protect (does not allow data to be written to memory). The default setting is
Write Back.
