Halt On

This field allows you to decide which errors, detected during the Power On Self

Test (POST), will halt the system.

Base Memory / Extended Memory / Total Memory

This field displays the amount of memory detected by the system during boot

up. This is a display only field. You cannot make any changes to this field.

Base Memory: Indicates the memory installed below the conventional

1MB space.

Extended Memory: Indicates the memory installed above the 1MB space.
Total Memory: Indicates the total memory installed in the PC system.

Virus Warning

When you enable the virus warning you will receive a warning message when-

ever a program (specifically, a virus) attempts to write to the boot sector or

the partition table of the hard disk drive. If you receive such a message you

should immediately run an anti-virus program. Keep in mind that this feature

only protects the boot sector and not the entire hard drive.

Note: Disk diagnostic programs that access the boot sector table can trigger
the virus-warning message. If you run such a program, recommend that you

first disable the virus warning.

CPU L1 & L2 Cache Internal Cache / External Cache

This BIOS setting can be used to enable or disable the CPU’s L1 (primary) and

L2 (secondary) cache.

Quick Power On Self Test

If enabled the amount of time required to run the power-on self-test (POST)

will decrease. A quick POST skips certain steps. We recommend that you dis-

able quick POST. It is better to find a problem during POST than to lose data

during your work.
