85 Parameter VGA Palette Snoop Plug and Play Operating System Reset Resource Assignments Description Option This parameter permits you to use the palette snooping feature if you installed more than one VGA card in the system. The VGA palette snoop function allows the control palette register (CPR) to manage and update the VGA RAMDAC (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 RAMDACs. The signal goes through the cards continuously until all RAMDAC data has been updated. This allows the display of multiple images on the screen. Note: Some VGA cards require specific settings for this feature. Check your VGA card documentation before setting this parameter. Disabled Enabled When this parameter is set to Yes, BIOS No initializes only PnP boot devices such as Yes SCSI cards. When set to No, BIOS initializes all PnP boot and non-boot devices such as sound cards. Note: Set this parameter to Yes only if your operating system is Windows 95/98 or Windows 2000. Set this parameter to Yes to avoid IRQ No conflicts when installing non-PnP or PnP Yes ISA cards. This clears all resource assignments and allows BIOS to reassign resources to all installed PnP devices the next time the system boots. After clearing the resource data, the parameter resets to No.

VGA Palette
Snoop
This parameter permits you to use the
palette snooping feature if you installed
more than one VGA card in the system.
The VGA palette snoop function allows
the control palette register (CPR) to
manage and update the VGA RAMDAC
(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
RAMDACs.
The signal goes through the
cards continuously until all RAMDAC data
has been updated.
This allows the display
of multiple images on the screen.
Note:
Some VGA cards require specific
settings for this feature. Check your VGA
card documentation before setting this
parameter.
