Operation 3-25
3.9.2 Switching to DIGITAL UNIX or OpenVMS
Use the following procedure.
1. Shut down the operating system and power off the system.
2. Remove and mark the physical location of each disk in the system.
3. Either place blank disks or your DIGITAL UNIX or OpenVMS disk set into the
system. No matter which disk set you are placing into the system, be sure
that each disk is placed in the same physical location from which it was
removed.
4. Power on the system.
5. In AlphaBIOS, access the Advanced CMOS Setup screen and change the
Console Selection to DIGITAL UNIX (SRM) or OpenVMS (SRM) as
appropriate. Press F10 to save the change. This menu selection changes the os-
_type environment variable to either UNIX or VMS so that the SRM console
does not load AlphaBIOS but remains in the system when you reset the system.
6. Press the Reset button to reset the system.
7. Either install DIGITAL UNIX (see Section 3.4 ) or OpenVMS (see Section 3.6)
or boot the operating system.
