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 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.
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.
