General Troubleshooting
The following procedures can be used for troubleshooting in all the
Windows operating systems. For troubleshooting specifically in
Windows NT 4.0, see Troubleshooting in Windows NT 4.0 on
page A-5.
What if I can’t load the driver and suspect that it is an IRQ conflict?
The PCI specification allows the motherboard manufacturer to
determine the IRQ assignment for each PCI device. Check with the
motherboard/computer manufacturer for the specific PCI
configuration details of your system.
These are some basic steps that can assist the motherboard in
correctly allocating resources to your PCI devices and/or resolve
existing IRQ conflicts:
1 Move the PCI SCSI card to a PCI slot that is not forced to share
an IRQ with any other PCI, AGP, or ISA slot. These are usually
the PCI slots in the middle of the PCI expansion. You will need
to check with the motherboard/computer manufacturer for the
specific PCI configuration details of your system.
