Troubleshooting & Tips
This section is used to assist with troubleshooting conflicts and RAID Function
installation problems.
The section is divided into the following categories: Motherboard Issues, System
CMOS Issues, Drive Errors, Operating System Errors, and Audio/Video Editing Tips.

7-1 Motherboard Issues

Freeing additional IRQ resources
Since the RAID Function controller supports PCI Interrupt sharing, it is possible to
use IRQs already assigned to another PCI card. Interrupt Sharing is not supported with
onboard IDE controllers. If the onboard IDE controller(s) are not used, you may disable
the controllers to free IRQ 14 and/or 15.
Configuring PCI IRQ resources
Setting the IRQ for a particular PCI slot will be different depending on the motherboard
BIOS. This setting is usually made in the PCI Configuration and/or Plug and Play (PnP)
section of the motherboard BIOS setup. There are three common methods that
motherboard BIOS's handle assignment of IRQs to PCI slots:
1. Specifically assigning an IRQ to a particular slot - You can tell the motherboard to use
IRQ 10 for PCI slot 1, IRQ 11 for PCI slot 2, etc.
2. Listing which IRQs are available to be assigned to the PCI slots - This BIOS has an
option where you specify "1st Available IRQ", "2nd Available IRQ", etc. The BIOS
then scans the PCI slots for PCI cards and assigns these IRQs in the order that it
finds the PCI cards.
3. Excluding an IRQ from being used by a PCI slot - If you have an ISA card that is
using an IRQ, change the setting for this particular IRQ from "Available" to "used by
ISA card" so that the motherboard will not assign this IRQ to a PCI slot.
Consult your motherboard manual for information that is specific to your motherboard.
System locks up during bootup or when Windows starts
There may be a possible IRQ conflict with an ISA card. Identify what IRQs are used by
ISA cards, enter the Mainboard PCI Setup, and reserve the IRQ for use with ISA. PCI
slots cannot share IRQs with ISA cards.
