Description
Save CMOS also in
Flash En. En. Dis. ; En. When enabled, saves the CMOS parameters in the Flash memory
which makes them available in the case of a battery failure.
PanelLink Adjustment 7 7 0 to 15 Use this option to control the voltage drive of the PanelLink interface.
Increase the value to obtain a higher drive voltage.
Video BIOS Shadow En. En. Dis. ; En. Software that resides in a read-only memory (ROM) chip on a device
called firmware. The Award BIOS allows shadowing of firmware
CC000-CFFFF
Shadow
Dis. Dis. Dis. ; En.
such as the system BIOS, video BIOS, and similar operating
instructions that come with some expansion peripherals (for
example, a
D0000-D3FFF Shadow Dis. Dis. Dis. ; En. SCSI adaptor). Shadowing copies of firmware from ROM into system
RAM, where the CPU can read it through the 16-bit or 32-bit DRAM
bus.
D4000-D7FFF Shadow Dis. Dis. Dis. ; En.
Firmware not shadowed must be read by the system through the 8-
bit X-bus. Shadowing improves the performance of the system
D8000-DBFFF Shadow Dis. Dis. Dis. ; En. BIOS and similar firmware for expansion peripherals, but it also
reduces the amount of high memory (640KB to 1MB) available for
loading device drivers, etc. Enable shadowing into each section of
memory separately. Many system designers hardwire shadowing of
the system BIOS and eliminate a System BIOS Shadow option.
DC000-DFFFF
Shadow Dis. Dis. Dis. ; En. Video BIOS shadows into memory area C0000-CBFFF. The
remaining areas shown on the BIOS Features Setup screen may be
occupied by other expansion card firmware. If an expansion
peripheral in your system contains ROM-based firmware, you need
to know the address range the ROM occupies to shadow it into the
correct area of RAM.
