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.
Hyper-Threading Technology
The Hyper-Threading Technology is developed by Intel
®
Corporation, It allows
a single physical processor to excute multiple threads (instruction streams)
simultaneously to provide greater performance on the system.
APIC Mode
The APIC Mode is used to enable or disable the mainboard’s APIC (Advanced
Programmable Interrupt Controller) BIOS feature. APIC is usually used
together with Hyper-Threading Technology or used in multiprocessor main-
board, APIC allows better IRQ management.
But note that APIC is not supported on Win95 and Win98.

1MB space.

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.
