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 the VGA Palette Snoop bit is:
Snoop Bit
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 palette registers and the ISA VGA device palette
registers, and the palette registers of both devices can be identical.
This option must be set to Enabled if an ISA adapter card installed in the
system uses VGA palette snooping. The Optimal and Fail-Safe default settings
are Disabled.
