CPU Internal / External
Cache
Cache memory is additional memory that is much
faster than conventional DRAM (system memory).
CPUs from 486-type up contain internal cache
memory (L1), and most, but not all, modern PCs
have additional (external) cache memory (L2).
When the CPU requests data, the system transfers
the requested data from the main DRAM into cache
memory, for faster access by the CPU.
Virus Warning
When enabled, you receive a warning message if a
program (specifically, a virus) attempts to write to
the boot sector or the partition table of the hard disk
drive.
You should then run an antivirus program. Keep in
mind that this feature protects only the boot sector,
not the entire hard drive.
NOTE: 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 dis-
able the virus warning.
Boot Up Floppy Seek
When enabled, the BIOS tests (seeks) floppy drives
to determine whether they have 40 or 80 tracks. Only
360-KB floppy drives have 40 tracks; drives with
270KB, 1.2MB, and 1.44MB capacity all have 80
tracks. Because very few modern PCs have 40-track
floppy drives, we recommend that you set this field
to disabled to save time.
Swap Floppy Drive
When enabled, floppy drives A and B will be exchanging
without any physical connection and modification on the
cables.
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/
Other Boot Device
The BIOS attempts to load the operating system from
the devices in the sequence selected in these items.
The choices: Floppy; LS/ZIP; HDD; SCSI; CDROM;
Disabled
