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:
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.
