Boot Priority

The Netserver's boot order should be considered when selecting a boot device.
This is especially important if you are installing a board that requires a high
priority in the boot order. The board's boot priority is set by its location in the boot
order.

By default the Netserver searches for boot devices in this order:

1. IDE CD-ROM drive

2. Flexible disk drive

3. Embedded SCSI A channel (Hot Swap SCSI Drives), starting with SCSI ID 0

4. Embedded SCSI B channel (external SCSI Devices)

5. PCI slots 1, 2, and 3 (in that order)

6. Network connection

The embedded SCSI controller consists of two channels, A and B. Channel A is
used to control the Hot Swap SCSI hard drives (6). Channel B is used to control
the external SCSI devices. On each SCSI channel, the controller scans for a boot
device starting at device ID 0 and works through the ID numbers. The Netserver's
embedded controller is always SCSI ID 7.

For information about booting off of a hard disk connected to an accessory board,
see "Installing a Disk Array Controller Board" in Chapter 5, "Installing Additional
Boards." For information about using Channel B for duplex mode, see “Duplexing
Using Internal SCSI Channels” later in this chapter.
