Choose the PCI/PnP Setup icon from the
WINBIOS Setup screen to display the PCI and
Plug and Play Setup options, described below.
Plug and Play-Aware OS
Set this option to
Yes
if the operating
system in this computer is aware of and follows the
Plug and Play specification. Currently, only
Windows 95 is PnP-aware. The settings are
Yes
or
No.
The Optimal and Fail-Safe default settings are
No.
PCI VGA Palette Snoop
When this option is set to
Enabled,
multiple VGA devices operating on different buses
can handle data from the CPU on each set of
palette registers on every video device. Bit 5 of the
command register in the PCI device configuration
space is the VGA Palette Snoop bit (0 is disabled).
For example: if there are two VGA devices in the
computer (one PCI and one ISA) and:
VGA Palette
Snoop Bit
Setting
Action
Disabled
Data read and written by the CPU is only directed to
the PCI VGA device's palette registers.
Enabled
Data read and written by the CPU is directed to the
both the PCI VGA device's palette registers and the
ISA VGA device palette registers, permitting the
palette registers of both devices to be identical.
This option must be set to
Enabled
if any ISA
adapter card installed in the system requires VGA
palette snooping. The settings are
Enabled
or
Disabled.
The Optimal and Fail-Safe default
settings are
Disabled.
