3.4 Configuring the Hardware

Possible configuration tasks include selecting the console and display device; setting
environment variables; verifying the system configuration; and changing power-up or boot
values.

3.4.1 Selecting the Console and Display Device

The SRM os_type environment variable determines which user interface (SRM or AlphaBIOS)
is the final console loaded on a power-up or reset. The SRM console environment variable
determines to which display device (VT-type terminal or VGA monitor) the console display is
sent.
Selecting the Console
The os_type variable selects the console. Os_type is factory configured as follows:
•
For Windows NT, os_type is set to nt.
•
For Tru64 UNIX or OpenVMS, os_type is set to unix or vms, respectively.
If os_type is set to unix or vms, the SRM console is loaded on a power-up or reset. If os_type
is set to nt, the SRM console is loaded and then SRM starts the AlphaBIOS console from
system flash ROM.
Selecting the Display Device
The console terminal that displays the SRM user interface can be either a serial terminal
(VT320 or higher, or equivalent) or a VGA monitor.
The SRM console environment variable determines the display device.
•
If console is set to serial, and a VT-type device is connected, the SRM console powers on
in serial mode and prints power-up information to the VT device. The VT device can be
connected to the MMJ port or to COM2.
•
If console is set to graphics, the SRM console expects to find a VGA card connected to
PCI 0 and, if so, displays power-up information on the VGA monitor after VGA
initialization has been completed.
You can verify the display device with the SRM show console command and change the
display device with the SRM set console command. If you change the display device setting,
you must reset the system either with the Reset button or the init command to put the new
setting into effect.
In the following example, the user displays the current console device and then resets it to a
serial device:
P00>>> show console
console
P00>>> set console serial
P00>>> init

3.4.2 Setting the Control Panel Message

If you are running Tru64 UNIX or OpenVMS, you can create a customized message to be
displayed on the operator control panel after startup self-tests and diagnostics have been
completed.
