4.4 ADVANCED BIOS FEATURES
This section allows you to configure and improve your system and allows you to set up some system features 
according to your preference. 
 
 
 
Virus Warning
This item protects the boot sector and partition table of your hard disk against accidental modifications. If an 
attempt is made, the BIOS will halt the system and display a warning message. If this occurs, you can either 
allow the operation to continue or run an anti-virus program to locate and remove the problem. 
 
NOTE:
Many disk diagnostic programs, which attempt to access the boot sector table, can cause the virus 
warning. If you will run such a program, disable the Virus Warning feature. 
 
CPU Internal Cache 
Cache memory is additional memory that is much faster than conventional DRAM (system memory). CPUs from 
486-type on up contain internal cache memory, and most, but not all, modern PCs have additional (external) 
cache memory. When the CPU requests data, the system transfers the requested data from the main DRAM into 
cache memory, for even faster access by the CPU. These items allow you to enable (speed up memory access) 
or disable the cache function. By default, these items are Enabled. 
CPU L2 Cache ECC Checking
When enabled, this allows ECC checking of the CPU’s L2 cache. By default, this field is Enabled. 
 
Quick Power On Self Test
When enabled, this field speeds up the Power On Self Test (POST) after the system is turned on. If it is set to 
Enabled, BIOS will skip some items. 
 
Boot Sequence
This field determines the drive that the system searches first for an operating system. The options are:
A, C, SCSI
D, A, SCSI
SCSI, C, A
C, A, SCSI
E, A, SCSI

F, A, SCSI
LS/ZIP, C
