Autobooting The System; Successful Power-Up And Automatic Boot - Digital Equipment DECsystem 5500 Operation

Software manuals may instruct you to power up with the Function switch
set to breaks enabled, or up (dot inside the circle), and to use the boot
command.

2.4.2 Autobooting the System

By assigning values to environment variables, you can define a device from
which the system will automatically boot at power up. Use the setenv
command to assign values to the bootpath and bootmode environment
variables. The bootpath variable specifies a device from which to autoboot.
The bootmode variable must be set to a for the system to autoboot. For
example,
>> setenv bootpath rf(0,0,0)vmunix
>> setenv bootmode a
defines an RF-series ISE with controller 0, unit number 0, and logical block
number 0 as the boot device; and a value of a (autoboot) is assigned to the
bootmode variable. Now, when the system is powered up, the system runs
self-tests and, on completion, attempts to load system software from ISE 0.
For a complete description of the setenv and unsetenv commands, refer
to Section 2.11.

device has been specified.
