Chassis Plans
Plug and Play O/S
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.
PCI Latency Timer
Set this value to allow the PCI Latency Timer to be adjusted from 32 to
248. This option sets the latency of all PCI devices on the PCI bus.
Allocate IRQ to VGA
Yes
Set this value to allow the allocation of an IRQ to a VGA adapter card that
uses the PCI local bus.
No
Set this value to prevent the allocation of an IRQ to a VGA adapter card
that uses the PCI local bus.
Palette Snooping
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
PCI IDE Bus Master
Disabled
Set this value to prevent PCI bus mastering.
Enabled
This option specifies that the IDE controller on the PCI local bus has
mastering capabilities.
Off Board PCI/ISA IDE Card
Set this value to allow the Off Board PCI/ISA IDE Card to be selected.
Auto
This setting will auto select the location of an Off Board PCI IDE adapter
card.
PCI Slot1
This setting will select PCI Slot 1 as the location of the Off Board PCI IDE
adapter card. Use this setting only if there is an IDE adapter card installed
in PCI Slot 1.
PCI Slot2
This setting will select PCI Slot 2 as the location of the Off Board PCI IDE
adapter card. Use this setting only if there is an IDE adapter card installed
in PCI Slot 2.
IRQ
Set this value to allow the IRQ settings to be modified. Changing an IRQ
from Available to Reserved will remove it from the PCI PnP pool.
DMA
Set this value to allow the DMA channels to be modified from Available to
Reserved.
