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 CPU Internal Cache
Cache memory is an additional memory that is much faster than conventional DRAM(system
memory). Some CPU integrates a build-in Cache memory to speed up the data transferring.
This item allows you to enable or disable the inter Cache.
