Virus Warning
When this function is “Enabled”, you will 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 execute an anti-virus program. Keep in mind that this feature
protects the boot sector only, not the entire hard drive.

BIOS SETUP
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 this 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 and up contain internal cache memory. 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.
