CPU L1/L2 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.
CPU L2 Cache ECC Checking
When enabled, it allows ECC checking of the CPU L2 cache. Enabling
this feature is recommended because it will detect and correct single-bit
errors in data stored in the L2 cache. It will also detect double-bit errors
but not correct them.
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.
First/Second/Third Boot Device
These fields determine the drive that the system searches first for an
operating system. The options available include
Floppy , LS/ZIP ,
HDD-0 , SCSI , CDROM , HDD-1 , HDD-2 , HDD-3 , LAN and Disable .
Boot Other Device
These fields allow the system to search for an operating system from
other devices other than the ones selected in the First/Second/Third Boot
Device.
Swap Floppy Drive
This item allows you to determine whether or not to enable Swap Floppy
Drive. When enabled, the BIOS swaps floppy drive assignments so that
Drive A becomes Drive B, and Drive B becomes Drive A. By default,
this field is set to
Disabled.
Boot Up Floppy Seek
This feature controls whether the BIOS checks for a floppy drive while
booting up. If it cannot detect one (either due to improper configuration
or its absence), it will flash an error message.
