PCI /VGA Palette Snoop:
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 solve the display inversion to
black after you have used the MPEG card.
Assign IRQ For VGA :
Two options are available: Disabled or Enabled. The default setting is Enabled. Name the interrupt
request (IRQ) line assigned to the USB/VGA/ACPI (if any) on your system. Activity of the selected IRQ
always awakens the system.
You can assign an IRQ for the PCI VGA or Disabled.
Assigned IRQ For USB:
Two options are available: Disabled or Enabled. The default setting is Enabled. If you need another IRQ
to be freed up, you can choose to disable this item, and you can get an IRQ. But in some situations in
®
Windows 95 it may cause the USB port to malfunction or have other problems!
PIRQ_0~PIRQ3:
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. Which
means, the system can specify the fixed IRQ number for the device installed on the PCI slots (PCI slot 1
to PCI slot 6). This is a useful function 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
®
Windows NT, then you can specify the IRQ for the device installed on the new computer to fit the
original computer settings.
Note: If you specify the IRQ in this item, then you cannot specify the same IRQ to the ISA bus,
otherwise, it will cause a hardware conflict.
This feature is for the operating system that will record and fix the PCI configuration status, if you want
to change it.
For the relations between the hardware layout of PIRQ (the signals from the ICH chipset), INT# (means
PCI slot IRQ signals) and devices, please refer to the table below:
