Enabled: Activates automatically when the system boots up causing the following warning message to
appear when anything attempts to access the boot sector or hard disk partition table:

Disabled: No warning message will appear when an attempt is made to access the boot sector or hard
disk partition table.
Note: This function is available only for DOS and other operating systems that do not trap INT13. For
complete protection against viruses, install virus software in your operating system and update the
virus definitions regularly.
Many disk diagnostic programs that access the boot sector table can trigger the virus warning message.
If you plan to run such a program, we recommend that you disable the virus warning.
CPU L1 & L2 Cache
Cache memory is additional memory that is much faster than conventional DRAM (system memory). This
BIOS feature is used to enable or disable the processor’s Level 1 and Level 2 cache. Naturally, the default
and recommended setting is Enabled.
Hyper Threading Technology
The Intel Hyper-Threading Technology allows a single processor to execute two or more separate threads
concurrently. When hyper-threading is enabled, multi-threaded software applications can execute their threads
in parallel, thereby improving the processor’s performance.
Quick Power-On Self-Test
Select Enabled to reduce the amount of time required to run the Power-On Self-Test (POST). A quick POST
skips certain steps. We recommend that you normally enable quick POST.
First/Second/Third Boot Device
BIOS attempts to load the operating system from the devices in the sequence selected. The available choices
are: Floppy, LS120, HDD-0, SCSI, CDROM, HDD-1, HDD-2, HDD-3, ZIP100, USB-FDD, USB-ZIP, USB-
CDROM, USB-HDD, LAN, and Disabled.
Boot Other Device
If the selected boot devices fail to boot, selecting Enabled for this item allows the BIOS to boot from other
boot devices (in a predefined sequence) which are present but not selected as boot devices in the setup.
Boot Up Floppy Seek
Enable this to allow the system to search for floppy drives during the POST. Disable this item to boot faster.
Boot Up NumLock Status
Toggle between On or Off to control the state of the NumLock key when the system boot. If On, the numeric
keypad is in numeric mode. If Off, the numeric keypad is in cursor control mode.
! WARNING !
