SDRAM CAS Latency Time
You can select CAS latency time in HCLKs of 2/2 or 3/3. The system
board designer should set the values in this field, depending on the
DRAM installed. Do not change the values in this field unless you
change specifications of the installed DRAM or the installed CPU. The
choices are Auto, 2 and 3.
SDRAM Cycle Time Tras/Trc
The settings available for the SDRAM Cycle Time Tras/Trc are 6/8 and
5/7. The default setting is 6/8.
SDRAM RAS-to-CAS Delay
You can select RAS to CAS Delay time in HCLKs of 2/2 or 3/3. The
system board designer should set the values in this field, depending on
the DRAM installed. Do not change the values in this field unless you
change specifications of the installed DRAM or the installed CPU. The
choices are 2 and 3.
SDRAM RAS Precharge Time
This option defines the length of time for Row Address Strobe is
allowed to precharge. The choices are 2 and 3.
System BIOS Cacheable
The setting of Enabled allows caching of the system BIOS ROM at
F000h -FFFFFh, resulting in better system performance. However, if
any program writes to this memory area, a system error may result.
