Os_Type - HP AlphaServer TS15 Owner's Manual

5.20.6

os_type

The os_type environment variable specifies the default operating system. This variable
is set at the factory to the setting for the operating system you purchased. Use this
command to change the factory default setting.
The value of os_type takes effect only after you reset the system by pressing the halt/reset
button (if configured) or by issuing the init command. Jumper J22 pins 13-14 must be
installed for the halt/reset button to act as a reset. When the jumper is not installed, the
switch acts as a halt button.
The syntax is:
set os_type os_type
The options for os_type are:
OpenVMS Sets the default to OpenVMS. The SRM firmware is started during power-
or VMS up or reset.
Sets the default to Tru64 UNIX. The SRM firmware is started during
OSF or
power-up or reset.
UNIX
Example
The following command sets the default operating system to Tru64 UNIX.
>>> set os_type unix
>>> init
