using the bootstrap loader

3.2.7 %CONSOLE, %MANUAL, and %AUTO Macros
CONFIGURING THE FIRST STAGE
The CONSOLE, MANUAL, and AUTO macros specify how the first stage identifies the
file that the second stage will load (either the load file or the third stage) and the device on
which the file is found.
The syntax of the %CONSOLE, %MANUAL, and %AUTO macros is
%CONSOLE
% MANUAL
%AUTO
There are no parameters associated with any of these macros.
Depending on the action you want the Bootstrap Loader to take, you can include none,
any, or all these macros, and the combination you choose defines the set of actions taken.
Because the %MANUAL macro automatically includes both the %CONSOLE and
%AUTO macros, five functionally-distinct combinations are possible. Each of these
combinations requires that the device list at the end of the BS l.A86 or BS IMB2.A86 file
be set up in a certain way. For more information on the device list, see the discussion of
the %DEVICE macro later in this chapter. The following paragraphs list the possible
macro combinations, the device requirements, and the actions that the Bootstrap Loader
takes when each combination is invoked.

(Requires that the device list defined with %DEVICE macros have
only one entry.)
• The Bootstrap Loader tries once to load from the active device.
• The Bootstrap Loader tries once to load the file with the default
pathname (the one you define with the %DEFAULTFILE macro).
(Requires that the device list have only one entry.)
o The Bootstrap Loader tries once to load from the device in the device
list.
• The Bootstrap Loader displays an asterisk (*) prompt at the console
terminal and waits for you to enter the pathname of the file to load. It
tries once to load the file you specify.
If you enter a pathname, the Bootstrap Loader loads the file
with that pathname.
