5. Section 4.2 explains how to configure the workstation to boot into
multi-user mode automatically.
3.4 Boot Options
The IRIS boot environment is determined by the setting of configuration
switches 1 through 4 on the cabinet back panel. The two basic boot options are
automatic boot or PROM monitor boot:
Automatic boot At powerup, the IRIS tries to boot from a file called
defaultboot on the device specified by the
configuration switches (see Table 3-1 and Section
3.4.2).
PROM monitor boot At powerup, the IRIS enters the PROM monitor and
waits for further boot instructions (see Section 3.4.1).
To boot from a secondary video driver, see Chapter 8.
Since the IRIS can be booted from different devices (hard disks, tape drives,
etc.), the PROM monitor provides the ls command, a version of the U
nix
ls (1)
command, for displaying the names of the files on the attached devices. You
can specify a device name and a pathname in the ls . command (see Table 3-2).
For example,
ls /
searches the root file system (/) on the default device and lists
its contents. If you type
ls
without an argument, the IRIS displays a list of
files on the default device.
The IRIS is shipped with the configuration switches set for booting from the
PROM monitor. To select automatic booting, change the settings of the
configuration switches on the standard I/O panel. Table 3-1 lists the defined
configuration switch settings.
If you attempt to boot a nonexistent device or file from the PROM monitor, the
system prints an error message and returns you to the PROM monitor. If an
automatic boot fails, the system waits a few seconds and tries again.
Automatically booting an IRIS 3030 always fails on the first attempt after
power-up, but the automatic retry should succeed.
