BIOS Setup
System BIOS Cacheable
Selecting [Enabled] allows caching of the system BIOS ROM at F0000h-FFFFFh,
resulting in better system performance. However, if any program writes to this memory
area, a system error may result. Setting options: [Enabled], [Disabled].
Video BIOS Cacheable
Selecting [Enabled] allows caching of the video BIOS ROM at C0000h to C7FFFh,
resulting in better video performance. However, if any program writes to this memory
area, a system error may result. Setting options: [Enabled], [Disabled].
Memory Hole At 15M-16M
In order to improve performance, certain space in memory can be reserved for ISA
peripherals. This memory must be mapped into the memory space below 16MB. When
this area is reserved, it cannot be cached. Setting options: [Disabled], [Enabled].
DRAM Data Integrity Mode
Set this option according to the type of DRAM installed in your system: error-correct-
ing code (ECC) or parity (default). Setting optoins: [ECC], [Non-ECC].
PEG Force X1
The field enables or disables the PEG (PCI Express Graphic) port function. Setting
options: [Enabled], [Disabled].
