shadowing.

Items Description
Virus Warning This is the setting for the data write enable/ disable to the boot sector and partition table. For
the default setting, Fail-Safe is “Enabled” and Optimized is “Disabled”.
Enabled:This is the setting used to disable the write function. Although this setting protects the
system from viruses, it does not permit execution of FDISK or FORMAT.
Disabled:This is the setting used to enable the write function. Although FDISK and FORMAT can
be executed using this setting, it does not protect the system from viruses. Always use
the default setting.
External Cache This setting enables/disables the L2 Cache inside the CPU.
Enabled:Enables the L2 Cache. This is the normal setting.
Disabled:Disables the L2 Cache. This setting may have an adverse effect on the system
performance.
CPU L2 Cache
ECC Checking This is the setting that enables/disables the ECC check for the L2 Cache in the CPU. The default
setting is “Enabled”.
Enabled:This setting is used to perform the ECC check. This is the normal setting.
Disabled:This setting is used when the ECC check is not performed.
Processor
Number Feature
(This is displayed
only when the
CPU is in the
Pentium III
family.) This is a function for specifying whether or not to acquire the serial number of a CPU model
added from the Pentium III processor.
Note that the default setting is "enabled" regardless of the model.
The BIOS acquires the family number of the CPU at startup and controls whether or not this item
is displayed, as follows:
Pentium III:This item is displayed and the setting can be changed.
Note that in the case of the Pentium III, changing the setting to "disabled" has no effect. It is
treated the same way as if "enabled" were set in processing.
Celeron: This item is not displayed and the setting cannot be changed.
See Intel Processor Identification and the CPUID Instruction, published by Intel Corporation, for
the details of the CPU information.
Quick Post Sets POST processing conditions. The default setting Quick Post is set as “Disabled” and the
Quick Power On Self Test is set as “Enabled”.
Enabled:This setting is used to perform the memory test when rebooting after resetting the
software or when auto detection of the IDE device is omitted. This makes it possible to
reduce the time required for rebooting via software reset.
Disabled:This setting is used to perform the memory test when rebooting after resetting the
software or when auto detection of the IDE device is not omitted.
Quick Power On
Self Test Sets POST processing conditions. The default setting Quick Post is set as “Disabled” and the
Quick Power On Self Test is set as “Enabled”.
Enabled:This setting is used to execute the POST processing (memory self diagnostic test) only
once during startup. This setting can be used to reduce the time required for startup.
The ESC key may be pressed during POST to skip the processing.
Disabled:This setting is used to execute the POST processing (memory self diagnostic test)
several times during startup. The ESC key may be pressed during POST to skip the
processing.
First Boot Device This setting sets the search order for the startup device. The search is performed in the order of
First -> Second -> Third device and starts up from the first device that is capable of performing
the startup (one that has a boot sector and that can be loaded with IPL).
For both the default setting and Fail-Safe/Optimized, the settings are First =”Floppy”, Second
=”HDD-0” and Third = “SCSI”. Change the setting so that it is compatible with the system
configuration.
