SRM Console 2-47
2.19.11 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 purchased. Use this command to change the
factory default setting. Whenever you change the value of
os_type, you must reset the system by pressing the Halt/Reset
button or issuing the initialize command.
Syntax: set os_type
os_type
where os_type can be:
unix
Tru64 UNIX is the default operating system, and the SRM
firmware is started during power-up or reset.
openvms
OpenVMS is the default operating system, and the SRM firmware
is started during power-up or reset.
nt
Windows NT is the default operating system. The SRM firmware
is started, and it loads and starts the AlphaBIOS firmware during
power-up or reset. (If a halt assertion condition exists, this
environment variable is overridden, and the SRM firmware does
not load and start the AlphaBIOS console.)
2.19.12 password
Sets or clears the console password stored in NVRAM.
Syntax: set password
where the password is not an argument to the set password command; the
console prompts the user for the string, which must be between 15 and 30
characters.
