Chapter 6: Troubleshooting & Tips
This section is used to assist with troubleshooting conflicts and FastTrak S150
TX2plus installation problems. Also refer to the README.TXT file on the
FastTrak S150 TX2plus driver and utility diskette for more recent information as
well as the PromiseOnline services listed in Appendix B.
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.
Consult your motherboard manual for information that is specific to your
motherboard.
Intermittent data problems
Overclocking the PCI bus may cause the system to hang or data corruption. If
you experience either of these problems and you are overclocking the PCI bus,
set the PCI bus back to its normal setting to see if this is causing the errors.
