Clear NVRAM during System Boot.
4.1.3.2 Plug & Play O/S
Set this value to allow the system to modify the settings for Plug and Play operating system
support.
Item Description
No
The No setting is for operating systems that do not meet the Plug and Play
specifications. It allows the BIOS to configure all the devices in the system.
Yes
The Yes setting allows the operating system to change the interrupt, I/O, and DMA
settings. Set this option if the system is running Plug and Play aware operating systems.

Set this value to allow the PCI Latency Timer to be adjusted. This option sets the latency of
all PCI devices on the PCI bus.
The options: 32, 64, 96, 128, 160, 192, 224, 248 PCI clock cycles.

Disabled
This is the default setting and should not be changed unless the VGA card manufacturer
requires Palette Snooping to be Enabled.
Enabled
This setting informs the PCI devices that an ISA based Graphics device is installed in
the system. It does this so the ISA based Graphics card will function correctly. This does
not necessarily indicate a physical ISA adapter card. The graphics chipset can be
mounted on a PCI card. Always check with your adapter card’s manuals first, before
modifying the default settings in the BIOS.

Item Description

This setting allows the specified IRQ to be used by a PCI/PnP device.
Reserved
This setting allows the specified IRQ to be used by a legacy ISA device.
