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 anti-virus 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 first disable the virus warning.
CPU Internal Cache/External 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.
The External Cache field may not appear if your system does not have external
cache memory.
CPU L2 Cache ECC Checking
Enables Error Checking and correction (ECC) on the L2 cache onboard the
CPU.
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 disable quick POST. Better to find a problem during POST than lose
data during your work.
Boot Sequence
The original IBM PCs loaded the operating system from drive A (floppy disk),
so IBM PC-compatible systems are designed to search for an operating system
first on drive A, and then on drive C (hard disk). However, modern computers
usually load the operating system from the hard drive, and may even load it
from a CD-ROM drive. The BIOS now offers a large number of boot devices
and boot sequence options.
