Cache Memory
Cache - cache utilization
This field switches the cache on and off. The cache is a buffer to which parts of the
main memory and BIOS can be temporarily copied. The PC's performance is
higher when the cache is switched on.
You must disable the cache if:
– the access time is too short for older applications
– you are installing
OS/2 Warp
Intern Only
Only the internal cache is used.
Intern And Extern
Internal (first-level cache) and external cache (second-level cache)
are enabled. If there is no external Cache, only the internal cache is
used (Default entry).
Disabled
Internal (first-level cache) and external cache (second-level cache)
are disabled. All cache-related settings are then without effect.

Settings in BIOS Setup Advanced
Cache Mode
Condition: The
Cache
field
must be set to
Intern Only
or
Intern And Extern
.
Cache Mode
sets the mode in which the CPU uses the cache.
In write-back mode the CPU writes information to the cache and the information is
only written to main memory if necessary. Memory and cache contents are not
identical. In write-back mode the performance is higher than in write-through mode.
In write-through mode the processor writes the information to the cache and to
main memory. The contents of memory and cache are identical.
Write Back
The cache works in write-back mode (fixed).
Cache System BIOS Area / Cache Video BIOS Area
Condition: The
Cache
field
must be set to
Intern only
or
Intern and Extern
.
Cache System BIOS Area
and
Cache Video BIOS Area
lets you specify the BIOS that
should be mapped to the cache. Mapping the BIOS to the cache increases system
performance.
Enabled
The specified BIOS is mapped to the cache (default entry).
Disabled
The specified BIOS is not mapped to the cache.
Cache Memory Regions
Condition: The
Cache
field
must be set to
Intern only
or
Intern and Extern
.
Cache Memory Regions
lets you specify the BIOS ROM areas that should be
mapped to the cache. Mapping the BIOS ROM areas to the cache increases
system performance.
Enabled
The relevant ROM area is mapped to the cache.
Disabled
The relevant ROM area is not mapped to the cache (default entry).
