Figure 3-4 Advance Chipset Features
All of the above settings have been determined by the motherboard
manufacturer and should not be changed unless you are absolutely sure of
what you are doing. Explanation of the DRAM timing and chipset features
setup is lengthy, highly technical and beyond the scope of this manual. Below
are some abbreviated descriptions of the functions in this setup menu.
AGP Aperture Size (MB):
This function determines the amount of system memory that is given to the AGP
card. Options range from
32MB
to
512MB
. This is a dynamic memory allotment in
that the AGP card will only use the amount of memory that it needs. The remaining
memory, which is not in use, will be available for the system. For example, if 16MB
is allotted to the AGP card and the card only needs 8MB, the remaining 8MB will be
available for system use.
Flash BIOS Protection:
The motherboard manufacturer developed BIOS protection technology that protects
the System BIOS from accidental corruption by unauthorized users or computer
viruses. When enabled, the BIOS data cannot be changed when attempting to update
BIOS with the FLASH utility. When disabled, the BIOS data can be updated by
using the FLASH utility.
