AlphaBIOS Firmware
8-45
Up to three versions of Windows NT can be installed at the same time. This can be
very useful in a variety of circumstances
for example, when testing application
compatibility across different versions of Windows NT.
Each time you install a separate version of Windows NT, a new operating system
selection is created. Although you can start any of the installed versions of Windows
NT, one of them must be the primary operating system. The version of Windows NT
you select as the primary operating system is the one that automatically starts if the
Auto Start option is enabled in AlphaBIOS.
Figure 8-29 illustrates the relationship between multiple-operating-system installations,
Auto Start, and the primary operating system.
➊
The primary operating system is listed first on the Boot screen.
➋
The primary operating system starts automatically if the Auto Start option is
enabled in CMOS Setup.
➌
The primary operating system can be selected in the Operating System
Selection Setup screen.
Follow this procedure to designate a new primary operating system:
1. From
the
AlphaBIOS Setup screen select Utilities. In the selection box that
displays, choose OS Selection Setup.
2. The
Operating System Selections Setup screen displays. Select the primary
operating system from the list displayed.
