Adaptec SCSI RAID 2010S/2015S Installation Guide
The Setup may also have another entry for controlling the hard
drive sequence to be used. This entry, which may be on the same
screen, or in a subsequent screen, will order the system’s on-board
drive, usually the IDE drive, and that of the controller that is being
added. Make the controller the first hard disk drive to be used if
you wish to start the system from the controller’s array.
Save and Exit the system’s BIOS area. Restart the system. See the
next section for details on setting up the controller.
Configuring the Controller to Boot from Channel 1
The controller defaults to enable booting from either channel when
the ZCR motherboard is fitted with an Adaptec 7902W SCSI
controller. In this case the controller will attempt to boot from the
first array found. If arrays exist on both channels; the first array
found, and therefore the boot device, will be the one with the
lowest SCSI ID on channel 0.
If you wish to boot from an array on channel 1, you will need to
disable booting for channel 0. To do this:
1 Restart the system, press Ctrl-A when the controller BIOS
displays.
2 When the blue screen of the SMOR display appears, highlight
Channel 0 on the card on the left side, and tab to switch to the
right side.
3 Highlight the [o] Bus Boot Enable and press the Spacebar to
toggle the switch off, the o will disappear. The system will now
bypass Channel 0 as a bootable channel.
4 Press the Esc key.
5 When asked to save changes, tab to yes and press Return.
6 Exit SMOR and allow the system to restart.
Controller IRQ and Address
Both the IRQ and address space used are not set by the user.
During the host system start process, the system BIOS should
automatically configure the controller BIOS Interrupt Request
(IRQ) level and memory location for all Adaptec PCI controllers in
the system.
