PCI IRQ Setting
This parameter allows for automatic or manual configuration of PCI devices. If
you use Plug and Play devices, you can keep the default setting Auto. The
system then automatically configures the Plug and Play devices. If you install
non-Plug and Play adapter cards, set this parameter to Manual. This allows
you to assign resources to non-Plug and Play cards first.
If you have to configure PCI resources manually, use the up- or down-arrow
key to move between fields and select the IRQ assignments using the left- or
right-arrow key.
PCI Slots These parameters allow you to specify the appropriate PCI
devices. You may assign IRQ3, IRQ4, IRQ5, IRQ7, IRQ9, IRQ10, IRQ11,
IRQ12, IRQ14, or IRQ15 if they have not been previously assigned to other
devices. Some IRQs are normally assigned to specific system devices. See
“System Interrupts” on page 1- 12 to make sure that the IRQ that you want to
use is free to avoid resource conflicts.
Bus mastering When set to Enabled, this option allows the PCI cycles to
bypass the CPU for faster operation. When set to Disabled, all PCI
transactions pass through the CPU. The default setting is Enabled.
PCI IRQ Sharing
When set to Yes, this parameter allows you to assign the same IRQ to more
than one PCI device installed in the system. When set to No, you must assign
different IRQs to the PCI devices. The default setting is Yes.
VGA Palette Snoop
The VGA palette snoop function allows the system to refresh all ISA and PCI
graphic adapters installed in the system. This is needed if you install an
additional graphics overlay card such as an MPEG or an advanced 3D
graphics adapter. If the image on your monitor has problems after installing
such an adapter, set this parameter to Enabled. Otherwise, leave it to the
default Disabled to achieve better performance.
Plug and Play OS
When this parameter is set to Yes, BIOS initializes only Plug and Play boot
devices, then the Plug and Play operating system takes care of the other
devices. When set to No, BIOS initializes all Plug and Play boot and non-boot
devices.
Set this parameter to Yes if you are using the Windows 95 operating system.
Set to No if you run any other operating system. The default setting is Yes.
