reasons: first, ROM has (relatively) long access times and the
processor can access RAM faster than ROM; second, the contents
of RAM can be cached for even greater performance. All of the
computer’s system BIOS ROM is shadowed.
The ROM Shadowing option allows you to shadow video BIOS
and up to three 32 Kbyte areas of expansion card ROM (that is,
ROM fitted on ISA or PCI expansion cards) addressed between
C8000h and DFFFFh.
See the chapter entitled “Adding Expansion Cards” for more
information about addressing expansion card ROM.
Caution
Shadowing is only appropriate for expansion card ROM. It must
not
be
enabled for expansion card RAM.
PCI Options
The only configurable PCI setting is Palette Snooping, which can
be
Enabled
or
Disabled
. It should be enabled only for PCI video
expansion cards that require it.
Universal Serial Bus (USB)
This option is not used because this model does not have a USB
port.
Plug and Play
If your system uses a Plug-and-Play (PnP) compliant operating
system, such as Windows 95, you can set the Plug-And-Play
Adapter Configuration option to
Disabled
. This allows the
operating system to configure PnP devices. If this option is
Enabled
,
PnP devices are configured by the BIOS during system start-up.
Note that some PnP devices need to participate in the start-up
process and these are always configured by the BIOS regardless of
the setting of this option.
After fitting an ISA expansion card in your computer, you should
mark as
ISA Legacy
those system resources that the card uses. This
needs to be done because the system cannot detect their being in
