CPU Internal Cache / External Cache
Cache memory is additional memory that is much faster than conventional DRAM (system
memory). CPUs from 486-type up contain internal cache memory, and most, but not all,
modern PCs have an additional (external) 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, the ECC checking will ensure that the data stored on the L2
cache is accurate.
Quick Power On Self Test
If enabled the amount of time required to run the power-on self-test (POST) will de-
crease. A quick POST skips certain steps. We recommend that you disable quick POST. It
is better to find a problem during POST than to lose data during your work.
Halt On
This field allows you to decide which errors, detected during the Power On Self Test
(POST), will halt the system.
Base Memory / Extended Memory / Total Memory
This field displays the amount of memory detected by the system during boot up. This is a
display only field. You cannot make any changes to this field.
Base Memory: Indicates the memory installed below the conventional 1MB
space.
Extended Memory: Indicates the memory installed above the 1MB space.
Total Memory: Indicates the total memory installed in the PC system.
Virus Warning
When you enable the virus warning you will receive a warning message whenever a
program (specifically, a virus) attempts to write to the boot sector or the partition table of
the hard disk drive. If you receive such a message you should immediately run an anti-
virus program. Keep in mind that this feature only protects the boot sector and not the
entire hard drive.
Disk diagnostic programs that access the boot sector table can trigger the virus-warning
message. If you run such a program, recommend that you first disable the virus warning.
