AlphaBIOS Console 3-37
Three versions of Windows NT can reside on the system at the same time. This
is 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 that you select as the primary operating system is the one that
automatically starts if the Auto Start option is enabled in AlphaBIOS.
Figure 3–24 illustrates the relationship between multiple installations of the
operating-system, 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 is displayed, choose OS Selection Setup.
2.
The Operating System Selection Setup screen is displayed. Select the
primary operating system from the list displayed.
