3-3 Advanced Chipset Features
By choosing the [
Advanced Chipset Features
] 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 motherboard.
All of the above settings have been determined by the mother
board
manufacturer and should not be changed unless you are absolutely sure of
what you are doing. Explanation of the DRAM timing and chip
set 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.
