Boot Device Priority Use the following boot device priority for determining which device will be the boot device for the server. The NetServer searches for a bootable device in this order: 1. IDE CD-ROM Drive 2. Flexible Disk Drive 3. IDE hard disk drive 4. PCI slot devices in this order: • Slot 3 • Slot 1 • Slot 2 • Slot 4 If any of these slots have an Adaptec 2910 BUi SCSI adapter board, SCSI devices connected to this controller will boot (before any other devices in the system) in this order: • ID 0 • ID 1 • ID 2 • ID 3 • ID 4 • ID 5 • ID 6 NOTE If more than 1 Adaptec 2910 BUi adapter is installed in this system, the PCI slot order determines which one will boot the system. If another adapter (other than a 2910 BUi) or DAC is installed, the 2910 BUi will always boot the system. If you want a SCSI adapter other than the 2910 BUi or a DAC to boot the system, you must first remove the 2910 BUi or disable its BIOS using SCSISelect (see procedure below). Boot order will then be determined by PCI slot order, as described above. With the 2910 BUi BIOS disabled, devices attached to the 2910 BUi will be recognized during POST and by the NOS once it loads. Due to BIOS limitations, a maximum of two 2910 BUi adapters is supported by this system. This limitation does not apply to other SCSI adapters. 54

Boot Device Priority
Use the following boot device priority for determining which device will be the boot device for the server. The
NetServer searches for a bootable device in this order:
1.
IDE CD-ROM Drive
2.
Flexible Disk Drive
3.
IDE hard disk drive
4.
PCI slot devices in this order:
•
Slot 3
•
Slot 1
•
Slot 2
•
Slot 4
If any of these slots have an Adaptec 2910 BUi SCSI adapter board, SCSI devices connected to this
controller will boot (before any other devices in the system) in this order:
•
ID 0
•
ID 1
•
ID 2
•
ID 3
•
ID 4
•
ID 5
•
ID 6
NOTE
If more than 1 Adaptec 2910 BUi adapter is installed in this system, the PCI slot
order determines which one will boot the system. If another adapter (other than a
2910 BUi) or DAC is installed, the 2910 BUi will always boot the system.
If you want
a SCSI adapter other than the 2910 BUi or a DAC to boot the system, you must first
remove the 2910 BUi or disable its BIOS using SCSISelect (see procedure below).
Boot order will then be determined by PCI slot order, as described above.
With the
2910 BUi BIOS disabled, devices attached to the 2910 BUi will be recognized during
POST and by the NOS once it loads.
Due to BIOS limitations, a maximum of two
2910 BUi adapters is supported by this system. This limitation does not apply to
other SCSI adapters.
