• SDRAM RAS-to-CAS Delay < 3 >
You can select RAS-to-CAS delay in HCLKs 2 or 3. The 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 installed CPU.
SDRAM RAS Precharge Time < 3 >
•
When synchronous DRAM is installed, the number of clock cycles of RAS precharge time depends on
the DRAM timing. Do not reset this field from the default value specified by system designer.
SDRAM CAS Latency Time < Auto >
•
You can select CAS latency time in HLCKs 2, 3 or Auto. The 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 installed CPU.
• SDRAM Precharge Control < Disabled >
• DRAM Data Integrity Mode < Non-ECC >
This option sets the data integrity mode of the DRAM installed in the system.
• System BIOS Cacheable < Disabled >
Selecting Enables allows caching of the system BIOS ROM at F0000h-FFFFh, resulting in better
system performance. However, if any program writes to this memory area, a system error may result.
• Video BIOS Cacheable < Disabled >
This item allows you to change the Video BIOS location from ROM to RAM. Video shadow wil increase
the video speed.
