is detected, pressing <F1> will enter Setup and the proper BIOS setting can
be adjusted to fix the problem. This normally happens when system hard-
ware has been upgraded and BIOS has not been set to recognize it.
Hit "DEL" Message Display
This option tells the system to display or not display the "Hit Delete to Enter
Setup" message. The settings are Enabled and Disabled.
Processor Serial Number
This option allows the operating system and applications to be able to read
the CPU serial number from your CPUs. The settings are Enabled and Dis-
abled. (*Note: This option is not available for Intel Celeron Processors be-
cause these processors do not contain a processor serial number.)
Internal Cache
This option is for enabling or disabling the internal CPU L1 cache. Settings
include Disabled, Write-Thru, Write-Back and Reserved. Disabled: This
option prevents the system from using the internal CPU L1 cache. This
setting should be used to slow the computer system down or to trouble-
shoot error messages. Write-Thru: This option allows the computer system
to use the internal CPU L1 cache as Write-Though cache. Write-Through
cache is slower than Write-Back cache. It performs write operations to the
internal L1 CPU cache and system memory simultaneously. Write-Back:
This option allows the computer system to use the internal CPU L1 cache as
Write-Back cache. Write-Back cache is faster than Write-Through cache.
Write-Back cache is a caching method in which modifications to data in the
cache aren't copied to the cache source until absolutely necessary. Write-
back caching is available on all CPUs supported by this BIOS. With these
CPUs, write operations stored in the L1 cache aren't copied to main memory
until absolutely necessary. This is the default setting.
System BIOS Cacheable
This option enables you to move the system BIOS to the memory cache to
improve performance. Settings are Enabled and Disabled.
