Configuring memory shadow
The system can configure the Memory
Shadow options or you
can manually set them. You can enable or disable shadowing of
your system and video memory and control the specific blocks
of ROM used for this purpose.
Your computer can access RAM faster than ROM. The options
on this screen allow your system to copy the contents of its
system and/or video ROM into RAM. When you use
shadowing, your system can perform certain operations faster,
providing a significant increase in performance.
Note
For the best system performance, always set the System
shadow and the Video shadow options to Enabled.
If you enable shadowing for specific blocks, the ROM located in
these blocks is copied to the shadow area.
Configuring chipset registers
The system can set your Advanced
Chipset
Control
options or you can manually change the values in the chipset
registers. setting these values correctly increases your system
performance; however, setting them incorrectly may cause
your system to malfunction or shut down. Be sure to set the
Auto Configuration option to Enabled to let the system
automatically configure these options to avoid problems.
However, if you connected a
scanner
or a parallel port network
adapter to your parallel port, you should set Auto
Configuration
to Disabled so you can change the
Printer Port Control option to PS2 made (for
bidirectional operation). The default setting for the parallel port
is
AT
mode (for unidirectional operation).
