Comments
Enables or disables the computer's internal cache.
The computer's external cache operates in write-back mode when
Enabled has been selected.
For optimal computer performance, keep this setting at Enabled.
The main logic board reserves an area of DRAM for a copy of system
BIOS ROM. This DRAM called "shadow memory" is write-protected
and has the same addresses as the system BIOS ROM locations.
When system BIOS ROM is shadowed, the ROM information is
copied into an appropriate area in DRAM. This increases the
computer's performance because the system BIOS instructions are in
fast DRAM instead of ROM.
This option enables the system BIOS to be cached in the internal
cache and external cache (if installed). This increases computer
performance because BIOS instructions can be executed in cache
instead of RAM.
This option enables the video BIOS to be cached in the internal cache
and external cache (if installed). This increases computer
performance because video BIOS instructions can be executed in
cache instead of RAM.
