Chapter 3
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.
AGP Frequency
This function determines the amount of AGP frequency that is given to the
AGP card. Options range from 50 MHz to 100 MHz . (default [ Auto (66MHz) ])
AGP 8X Support
Enable this setting to utilize the 8X mode (twice as fast as 4X) offered by
advanced AGP cards. Your VGA card must support 8X mode in order to take
advantage of the faster speed.
AGP Fast Write Capability
Selecting [ Enabled ] to allow Fast Write Protocol for 8x/4x AGP to function.
PS:
Not all AGP cards support fast write.
System BIOS Cacheable
Enabling this function allows caching of the system BIOS ROM at
F0000h-FFFFFh, resulting in better system performance. However, if any
program writes to this memory area, a system error may result. Caching the
system BIOS results in better performance than shadowing the system BIOS.
Video RAM Cacheable
Enabling this function will allows caching of the video RAM, resulting in
better system performance. However, if any programs write to this memory area,
a system error may occur.
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.
