Identifying the Server Boot Device
The server boot device can be defined in the SCU. For a bootable CD-
ROM or SBB drive to be the boot device, it must be attached to a SCSI
controller which has the lowest ROM address on either the EISA or PCI
bus. The SCSI controller must be installed on EISA or PCI bus 0. Your
server is configured from the factory with bootable CD-ROM support for
the Quick Launch program. In the event that the CD-ROM does not boot:
1. Verify that the “Bootable CD-ROM” is enabled in the SCSI Select
utility (under Advanced Configuration Options).
Refer to the “SCSISelect Utility” section in Chapter 2.
2. Ensure that the CD-ROM drive is attached correctly to the Adaptec
controller expansion board and that the board is the lowest ROM
address of all the storage controllers in the server.
Additionally, when the Quick Launch CD-ROM creates and loads utilities
onto the hard disk drive’s partition on the server, it will choose the first
hard disk drive that is found during the server scan sequence.
Server Bus Scan Order
ROM addresses on PCI expansion boards are assigned based on the PCI
scan order and what addresses are available at the time of the scan. The
bus scan order is as follows:
1. The EISA bus is scanned first, in ascending order from slot 1 to 5.
This means that if there is an EISA SCSI adapter and a PCI SCSI
adapter in the server, the EISA SCSI adapter will be scanned first
followed by the PCI adapter. The EISA ROM address will be either
its default setting or what was last set using the SCU. The PCI
adapter will be assigned the next available ROM address.
