AMI BIOS
Internal Cache Mode
The internal cache is normally set to Write-through . If you are
using a Cyrix CPU, you may change the setting to Write-back for
better performance.
Intel P24D also supports the Write-back mode.
CPU Burst Write
This parameter enables or disables the CPU cache burst-write mode
for M7, P24D and P24T. The default setting is
Disabled .
Shadow C800, D000, D800, 32K
This function is for shadowing other expansion card ROMs. The
default setting for these areas is
Disabled
.
If you have other
expansion cards with ROMs on them, you need to know the specific
addresses that the ROMs use to shadow them. Enable all the ROM
Shadow settings if you don't know the addresses. This ensures the
shadowing of any present ROMs.
The F000 and E000 addresses are
exclusively shadowed for BIOS.
Video Shadow
The default setting for this parameter is Enabled . This copies the
video display card BIOS into the system DRAM to improve system
performance.
