Virus Warning
When the 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 run an anti-virus program. Keep in mind that this feature protects the boot sector
only, 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 or up contain internal cache memory. Most, but not all, mod-
ern 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.
