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.
Allows 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 DACs 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.
This parameter determines the effective size of the
graphics aperture. Graphics aperture is the
address range that the AGP video and the CPU use
to manage graphical objects.
Set to Yes if the computer is running on Win95/
Win98 or Win2000. For any other OS, set to No.
