Virus Warning:
This item can be set to Enabled or Disabled, the default setting being Disabled.
When this feature is enabled, if there is any attempt from a software or an application to access the boot
sector or the partition table, the BIOS will warn you that a boot virus is attempting to access the hard disk.
CPU L1 & L2 Cache:
Two options are available: Disabled or Enabled. The default setting is Enabled. This item is used to
enable or to disable the processor’s level 1 and level 2 cache. When the cache is set to Disabled it is much
slower, so the default setting for this item is Enabled since it will speed up memory access. Some older
software will make the computer malfunction or crash if the system speed is too high. In this case, you
should disable this feature.
CPU L2 Cache ECC Checking:
Two options are available: Enabled or Disabled. The default setting is Enabled. This item is used to
enable or to disable the processor level 2 cache ECC checking function.
Quick Power On Self Test:
Two options are available: Disabled or Enabled. The default setting is Enabled. After the computer has

its peripherals. If the Quick Power on Self-Test feature is enable, the BIOS will simplify the test
procedures in order to speed up the boot process.
