3-3 Advance Chipset Features
By choosing the Advanced Chipset Features option from the Standard CMOS
Features 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. BANK 0/1, 2/3 & 4/5 DRAM Timing
This item allows youto select the value in this field, depending on whether the
board has paged DRAM or EDO (Extended Data Output) DRAMs.
B. SDRAM Cycle Length
When synchronous DRAM is installed, the number of the clock cycles of CAS
latency depends on the DRAM timing. Do not reset this setting from the default
value specified by the system designer.
