Chapter 6: Troubleshooting & Tips
This section is used to assist with troubleshooting conflicts and FastTrak
TX4000 installation problems. Also refer to the README.TXT file on the
FastTrak TX4000 driver and utility diskette for more recent information as well as
the PromiseOnline services listed in Appendix A.
The section is divided into the following categories: Motherboard Issues, System
CMOS Issues, Drive Errors, Operating System Errors, and Audio/Video Editing
Tips.
Motherboard Issues
Freeing additional IRQ resources
Since the Promise card 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:
• 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.
• 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.
• 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 boot up 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 Motherboard PCI Setup, and reserve the IRQ for
use with ISA. PCI slots cannot share IRQs with ISA cards.
