Configuring PCI IRQ resources
Setting the IRQ for a particular PCI slot will be different depending on the mother-
board 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 meth-
ods that motherboard BIOS's handle assignment of IRQs to PCI slots:
1) Specifically assigning an IRQ to a particular slot - You can tell the mother-
board 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 "Avail-
able" 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 mother-
board.
Set Mainboard CMOS Boot sequence to boot to FastT rak66
On some Mainboard BIOS, it is necessary to set the Boot sequence to "SCSI, A:,
C:" since the Promise card is identified as a SCSI card.
Mainboard CMOS displays C: or D: drive failure during startup
Do not reference C: or D: in the Mainboard Standard CMOS for drives attached to
the FastTrak66 controller. Only enter drive information in the Mainboard CMOS if
you have drives attached to a conventional add-on or onboard IDE controller.
Coexist with IDE hard drives
If an onboard IDE controller is installed with hard disks, enable support in the
Mainboard Standard CMOS Setup for the drives. Note that the onboard IDE hard
drives will then be the bootable hard disk unless the system BIOS has a boot
sequence setting with a "SCSI, A:, C:" option.
Drive cannot be formed into an array
Drives must support Ultra DMA or Multi-word DMA and be free of media defects
to be added into an array. Promise recommends to use new drives of the same
model. Re-secure data and power cabling while checking for proper alignment.
Typically, Pin 1 of the drive is closest to the power connector.
