Resources Controlled By:
When resources are controlled manually, assign each system interrupt as one of the following types,
depending on the type of device using the interrupt:
Legacy devices compliant with the original PC AT bus specification require a specific interrupt. PCI PnP
devices comply with the Plug and Play standard, whether designed for the PCI or legacy bus architecture.
Two options are available: Auto (ESCD) or Manual. The default setting is Auto (ESCD). The Award Plug
and Play BIOS has the capability to automatically configure all boot and Plug and Play compatible
devices. If you select Auto (ESCD), all of the interrupt request (IRQ) fields become unselectable, as the
BIOS automatically assigns them.
 IRQ Resources:
If you have trouble in assigning the interrupt resources automatically, you can select Manual to set
which IRQis assigned to which PCI Device or Reserved it. See the screen shot below.IRQ Resources:

PCI /VGA Palette Snoop:
Two options are available: Disabled or Enabled. The default setting is Disabled. This option allows the
BIOS to preview VGA Status, and to modify the information delivered from the Feature Connector of the
VGA card to the MPEG Card. This option can set the display inversion to black after you have used the
MPEG card.
PIRQ_0 Use IRQ No. ~ PIRQ_3 Use IRQ No.:
Eleven options are available: Auto, 3, 4, 5, 7, 9, 10, 11, 12, 14, 15. Default setting is Auto. This item
allows the system to automatically specify the IRQ number for the device installed on PCI slots. This
means that the system can specify the fixed IRQ number for the device installed on the PCI slots (or
onboard PCI devices). This is a useful function for when you want to fix the IRQ for a specific device.
For example, if you want to move your hard disk to another computer and don't want to re-install
