Irq Resources - Abit KG7-RAID User Manual

Introducing the BIOS 3-31

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 reserve it. See the screen shot below.
Figure 3-8B. IRQ Resources Setup Menu
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 solve 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. 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.
This feature is for the operating system which 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 VIA VT82C686B chipset),
INT# (means PCI slot IRQ signals) and devices, please refer to the table below:
