Description
Allows you to automatically or manually configure
the Plug-and-Play (PnP) devices installed in your
system. Refer to your device manual for
technical information about the PCI card.
Allow you to manually assign an interrupt for
each PCI device installed in your system. When
the PCI IRQ Settings is set to Auto, BIOS
automatically assigns the available IRQs to the
PCI devices.
Allows you to assign the same IRQ to two
different devices.
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
Auto or Manual
Yes or No
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.
