Shadow RAM
The system reserves 256 KB of random access memory (RAM) for the
shadow RAM function. This parameter has eight range addresses. When you
set these addresses to Enabled, the system BIOS, video BIOS, and I/O ROM
functions run directly from the shadow RAM for faster operation. When you
set them to Disabled, the functions run normally from ROM.
The address range E0000h - FFFFFh is for shadowing the system BIOS. This
item is always set to Enabled and is not user-configurable. The address range
C0000h - C7FFFh is for shadowing the video BIOS. Shadow RAM is set to
Enabled and is not user-configurable if the Auto Configuration Mode and the
Fast Boot Mode parameters on page 2 of the Basic System Configuration
menu are enabled. Otherwise, you can disable this item.
The remaining address ranges are for I/O ROM functions.
Internal Cache (CPU Cache)
This parameter enables or disables the internal cache memory. It is set to
Enabled and is not user-configurable if you enabled the Auto Configuration
Mode and Fast Boot Mode parameters on page 2 of the Basic System
Configuration menu. Otherwise, you can disable this item.
External Cache
This parameter enables or disables the external cache memory. It is set to
Enabled and is not user-configurable if you enabled the Auto Configuration
Mode and Fast Boot Mode parameters on page 2 of the Basic System
Configuration menu. Otherwise, you can disable this item.
ECC/Parity Mode Selection
This parameter permits you to enable or disable the ECC and parity check
feature. Fast-page mode SIMMs supports both ECC and parity mode while
EDO SIMMs supports only ECC mode.
