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.
CPU Internal Cache/External Cache
Cache memory is additional memory that is much faster than conven-
tional DRAM (system memory). CPUs from 486-type up contain internal
cache memory, and most, but not all, modern PCs have additional (exter-
nal) cache memory. When the CPU requests data, the system transfers the
requested data from the main DRAM into cache memory, for faster
access by the CPU.
CPU L2 Cache ECC Checking
When you select Enabled, it will speed up memory checking when the
external cache contains ECC SRAMs. The choices: Enabled; Disabled.
Processor Number Feature
Choose Disabled or Enabled. When enabled, the processor serial number
will display during the boot up screen.
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.
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 disable the virus warning.
