Description
Enables the palette snooping
feature if you installed more
than one VGA card in the
system, allowing the control
palette register (CPR) to
manage and update the VGA
RAM DAC (Digital Analog
Converter, a color data
storage) of each VGA card
installed in the system. The
snooping process lets the
CPR send a signal to all the
VGA cards so that they can
update their individual RAM
DACs. The signal goes
through the cards
continuously until all RAM
DAC data has been updated.
This allows the display of
multiple images on the screen.
Some VGA cards have
required settings for this
feature. Check your VGA card
manual before setting this
parameter.
Lets you specify whether BIOS
will initialize only PnP boot
devices such as SCSI cards,
or all PnP boot and non-boot
devices such as sound cards.
When enabled, avoids IRQ
conflict when installing non-
PnP and PnP ISA cards. This
clears all resource
assignments and allows BIOS
to reassign resources to all
installed PnP devices the next
time the system boots.
Options
Enabled or
Disabled
Yes or No
Yes or No
After clearing the
resource data, it is
recommended that
you reset the
parameter to its
default, i.e., No.
