system software is stored in a file called vmunix on the hard disk drive with
SCSI ID 2 connected to the base system module.

12.3.2.1 Setting the Boot Path Variable

If the boot path variable is wrong, or if you wish to change it, follow these
steps:
1. Determine the name of the device that stores the operating system software
and the number of the slot to which that device is connected. Most often,
the software will be stored on the internal hard disk (RZ2x) connected to
the base system module (slot 3). If the software for your workstation is
stored somewhere else, check the configuration display for the device name
and slot number.
2. Using the slot number and device name you determined in step 1, type
setenv boot "[slot number] /[device name]/ vmunix-a" and press Return.
3. Test your correction by typing boot and pressing Return. The operating
system should start up.
You can also set your workstation to start the operating system software
automatically when you turn on the power. Follow these steps:
1. At the console prompt (>>), type setenv haltaction b and press Return.
2. Turn off your workstation by pressing the 0 on the on/off switch on the
back of the system unit.
3. Turn your workstation on again. The operating system should start
automatically after the system has completed its power-up self-test.
If the operating system does not start up, you may have two or more
SCSI devices set to the same SCSI ID number. (See Section 6.3 for more
information.) Or, there may be no software installed on your drive. (See
Chapter 3 for information about software installation).
