modified if necessary. For example, a developer testing different versions of
OSLOADER.EXE can store the different versions in different locations and modify
this line to start the operating system with the different versions as needed.
During Operating System Selection Setup, the disk and partition for the location of
the boot file can be selected from a list of choices presented in a list box. To open a
list of values for the field, press the Alt and down arrow keys together. When you
select a boot file location and name, AlphaBIOS searches for the specified program
on the specified partition. If the search fails, a warning appears, saying that the file
does not exist. You are given the choice to continue with the changes anyway or to
cancel the operation and fix the problem.
Note that because the boot file must be located in a FAT partition, only FAT
partitions are available as the boot partition within the list box.
4. OS Path
The OS Path line describes the disk, partition, and path to the operating system root
directory for an operating system selection.
During Operating System Selection Setup, the disk and partition for the location of
the boot file can be selected from a list of choices presented in a list box. To open a
list of possible values for the field, press the Alt and down arrow keys at the same
time. When you select or enter an OS path, AlphaBIOS searches for the directory.
If the search fails, a warning appears, saying that the directory does not exist. You
are given the choice to continue with the changes anyway or to cancel the operation
and fix the problem.
5. OS Options
The OS Options line lists the startup parameters passed to the operating system for
an operating system selection. One example of a startup parameter is whether to
start the operating system in debug mode. By default, Windows NT does not add
any entries to this field. This field can be modified.
6. OS Selection Setup Options
You can use the options listed at the bottom of the menu to edit operating system
selections. When you edit an OS selection, the fields of the OS Selection are
validated when you exit the OS selection setup menu. Depending on the option you
choose, one of the following dialog boxes will appear.
New OS Selection
. Pressing the Insert key displays the Insert New Operating
System Selection dialog box, with default values for the new OS selection already
filled in. You can change these values as necessary.
Delete OS Selection
. Pressing the Delete key tags the currently selected OS
selection for deletion. Although the OS selection is removed from the menu, it is
not actually deleted until you save your changes.
