This section is used to assist with troubleshooting conflicts and SATA300
TX4302 Controller card installation problems. Also refer to the README.TXT file
on the CD for more recent information as well as “Technical Support Services” on
page 30.
The section is divided into the following categories: Motherboard Issues, System
CMOS Issues, Drive Errors and Operating System Errors.
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 two common methods that the motherboard BIOS uses to handle the
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.
