3-3 Chipset Features Setup
By choosing the Chipset Features Setup option from the CMOS Setup Utility menu
(Figure 3-1), the screen below is displayed. This sample screen contains the
manufacturer's default values for the mainboard.
All of the above settings have been determined by the mainboard 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 abbreviated descriptions
of the functions in this setup menu. You can look on the world wide web
for helpful chipset and RAM configuration information including AWARD's
web site at http://www.award.com.
A. Video BIOS Cacheable
Enabling this function allows caching of the video BIOS ROM at C0000h-C7FFFh,
resulting in better video performance. However, if any program writes to this
memory area, a system error may result. Caching the video BIOS results in better
performance than shadowing the video BIOS as discussed in Section 3-2.
