PCI Expansion Board Configuration Guidelines
•
PCI slots one through three support bus mastering 32-bit PCI expansion
boards.
•
PCI boards should be installed starting in PCI slot one.
NOTE:
Your server’s BIOS will automatically disable the onboard
video controller when a video expansion board is installed.
Connect the video cable to the video expansion board and the
server will boot normally.
•
The SCU automatically scans the PCI bus and will assign an IRQ and
I/O port address for any new PCI board installed in the server.
Configuring Your PCI Expansion Boards Using the SCU
When installing PCI expansion boards in your server, the SCU must be run to
configure these boards. For PCI expansion boards, the SCU will autodetect the
boards and assign IRQs to the boards. The ROM addresses for these PCI
expansion boards will be assigned based on the PCI scan order and address
availability.
Boot Devices
The SCU allows you to define the boot device location as:
•
Embedded SCSI controller
•
PCI expansion slot
For the embedded SCSI controller, the boot device will be the first bootable
device found starting at SCSI ID 0. The boot device on an expansion board will
be determined by the server boot sequence and PCI scan order. These are
discussed in the next sections.
