12.5. PCI PnP Menu
The PCI PnP menu allows users to change the advanced settings for PCI/PnP devices.
¾ Clear NVRAM
Use this item to clear the data in the NVRAM (CMOS). Here are the options for your selection, No and Yes.
¾ Plug & Play O/S
When the setting is No, use this item to configure all the devices in the system. When the setting is Yes and if
you install a Plug and Play operating system, the operating system configures the Plug and Play devices not
required for boot. The default setting is No.
¾ PCI Latency Timer
This item controls how long a PCI device can hold the PCI bus before another takes over. The longer the
latency, the longer the PCI device can retain control of the bus before handing it over to another PCI device.
There are several options for your selection.
¾ Allocate IRQ to PCI VGA
This item allows BIOS to choose an IRQ to assign for the PCI VGA card. Here are the options for your
selection, No and Yes.
¾ Palette Snooping
Some old graphic controllers need to “snoop” on the VGA palette, and then map it to their display as a way
to provide boot information and VGA compatibility. This item allows such snooping to take place. Here are
the options for your selection, Disabled and Enabled.
¾ PCI IDE BusMaster
This item is a toggle for the built-in driver that allows the onboard IDE controller to perform DMA (Direct
Memory Access) transfer. Here are the options for your selection, Disabled and Enabled.
¾ OffBoard PCI/ISA IDE Card
This item is for any other non-onboard PCI/ISA IDE controller adapter. There are several options for your
selection.
¾ IRQ3/4/5/7/9/10/11/
These items will allow you to assign each system interrupt a type, depending on the type of device using the
interrupt. The option “Available” means the IRQ is going to assign automatically. Here are the options for
your selection, Available and Reserved.
