PCI/VGA Palette Snoop
When 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 the:
The setting must be set to Enabled if any ISA bus adapter in the system requires
VGA palette snooping.
VGA Palette Snoop
Bit Setting Action
Disabled Data read or written by the CPU is only directed to the PCI
VGA device’s palette registers.
Enabled Data read or written by the CPU is directed to both the PCI
VGA device’s palette registers and the ISA VGA device’s
palette registers, permitting the palette registers of both
VGA devices to be identical.
PNP/PCI Configurations
This section describes configuring the PCI bus system and PnP (Plug & Play) feature.
PCI, or Peripheral Component Interconnect, is a system which allows I/O devices to
operate at speeds nearing the speed the CPU itself uses when communicating with
its special components. This section covers some very technical items and it is
strongly recommended that only experienced users should make any changes to the
default settings.
Init Display First
This setting specifies which VGA card is your primary graphics adapter. Setting
options are:
[PCI Ex] The system initializes the PCI Express graphic first. If a PCI Express
graphic card is not available, it will initialize the PCI graphic card.
[PCI Slot] The system initializes the PCI Graphic card first. If a PCI Graphic card
is not available, it will initialize the PCI Express graphic.
