display only field. You cannot make any changes to this field.

space.
Extended Memory:

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 whenever 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! Many disk diagnostic programs that access the boot sector table can trig-
ger the virus-warning message. If you plan to run such a program, we recom-
mend that you first disable the virus warning.
CPU L1 & L2 Cache
This BIOS setting can be used to enable or disable the CPU's L1 (primary) and L2
(secondary) cache.
CPU L2 Cache ECC Checking
When you select Enabled, the ECC checking will ensure that the data stored on the L2 cache
is accurate.
