4.4.1 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.
4.4.2 External Cache
Cache memory is additional memory that is much faster than conventional DRAM (system
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.
4.4.3 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.
