BIOS Setup
Limit CPUID MaxVal
The CPUID instruction of some newer CPUs will return a value
greater than 3. The default is Disabled because this problem does
not exist in the Windows series operating systems. If you are using
an operating system other than Windows, this problem may occur. To
avoid this problem, enable this field to limit the return value to 3 or
lesser than 3.
Execute Disable Bit
When this field is set to Disabled, it will force the XD feature flag to
always return to 0.
Virus Warning
This field protects the boot sector and partition table of your hard disk
drive. When this field is enabled, the Award BIOS will monitor the boot
sector and partition table of the hard disk drive. If an attempt is made
to write to the boot sector or partition table of the hard disk drive,
the BIOS will halt the system and an error message will appear.
After seeing the error message, if necessary, you will be able to run
an anti-virus program to locate and remove the problem before any
damage is done.
Many disk diagnostic programs which attempt to access the boot
sector table will cause the warning message to appear. If you are
running such a program, we recommend that you first disable this field.
Also, disable this field if you are installing or running certain operating
systems like Windows
®
95/98/2000 or the operating system may not
install nor work.
CPU L1 & L2 Cache
These fields speed up the memory access. The default value is
enabled. Enable the external cache for better performance.
CPU L3 Cache
This field is used to enable or disable the CPU’s L3 cache.
