Switch from Windows NT to AlphaBIOS Setup
Follow the instructions for switching from Windows NT to the SRM console. If the
auto_action environment variable has been set to boot, do not use the Secure
pushbutton or keyswitch. Simply let AlphaBIOS start automatically and press the F2
key at any time during its initialization process, but before the system boots.
If the auto_action environment variable has been set to halt, the system will halt with
an SRM console prompt. See the following instructions for switching from the SRM
console to AlphaBIOS Setup.
Switch from the SRM Console to AlphaBIOS Setup
To return to the AlphaBIOS firmware, issue the command alphabios at the SRM
console prompt. Then, to enter AlphaBIOS Setup, press the F2 key before the
operating system boots. If a Setup Password or Startup Password has been selected,
you will have to enter the correct password to enter AlphaBIOS Setup.
Switch from the SRM Console to Windows NT
To boot the Windows NT operating system from the SRM console, type the alphabios
command at the SRM console prompt. The AlphaBIOS firmware begins executing
and terminates with the boot screen. See Section 5.5 for the effect of various
environment variables and AlphaBIOS Setup options on how Windows NT is booted
from this screen.
