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 Choice: 2, 3.
DRAM Data Integrity Mode
Select Parity or ECC (error-correcting code), according to the type of installed
DRAM. The Choice: Non-ECC, ECC.
Cache Features
System BIOS Cacheable
Select 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.
Enabled
BIOS access cached
Disabled
BIOS access not cached
Video BIOS Cacheable
Select Enabled allows caching of the video BIOS ROM at C0000h-F7FFFh,
resulting in better video performance. However, if any program writes to this
memory area, a system error may result.
Enabled
Video BIOS access cached
Disabled
Video BIOS access not cached
40
Video RAM Cacheable
Select Enabled allows caching of the video RAM , resulting in better system
performance. However, if any program writes to this memory area, a system
error may result.
PCI and IDE Configuration
8 Bit I/O Recovery Time
The recovery time is the length of time, measured in CPU clocks, which the
system will delay after the completion of an input/output request. This delay takes
place because the CPU is operating so much faster than the input/output bus
that the CPU must be delayed to allow for the completion of the I/O.
This item allows you to determine the recovery time allowed for 8 bit I/O. Choices
are from NA, 1 to 8 CPU clocks.
16 Bit I/O Recovery Time
This item allows you to determine the recovery time allowed for 16 bit I/O.
Choices are from NA, 1 to 4 CPU clocks.
Memory Hole At 15M-16M
In order to improve performance, certain space in memory can be reserved for
ISA cards. This memory must be mapped into the memory space below 16 MB.
Enabled
Memory hole supported.
Disabled
Memory hole not supported.
