PCI/PnP Setup
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 installed in the
computer is Plug and Play-aware. AMIBIOS only detects and enables PnP
ISA adapter cards that are required for system boot. The Windows 95
operating system detects and enables all other PnP-aware adapter cards.
Windows 95 is PnP-aware. Set this option to No if the operating system (such
as DOS, OS/2, Windows 3.x) does not use PnP. You must set this option
correctly or PnP-aware adapter cards installed in your computer will not be
configured properly. The settings are No or Yes. 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 Optimal and Fail-Safe default
settings are Disabled.
