 Boot Commands

PmPPC7448 User’s Manual

The monitor uses the following basic command syntax:

• The command line accepts three different argument formats: string, numeric, and 

symbolic. All command arguments must be separated by spaces with the exception of 
argument flags, which are described below.

• Monitor commands that expect numeric arguments assume a hexadecimal base.

• All monitor commands are case sensitive.

• Some commands accept flag arguments. A flag argument is a single character that 

begins with a period (.). There is no white space between an argument flag and a 
command. For example, md.b 80000 is a valid monitor command, while md .b 80000 
is not.

• Some commands may be abbreviated by typing only the first few characters that 

uniquely identify the command. For example, you can type h instead of help. However, 
commands cannot be abbreviated when accessing on-line help. You must type help and 
the full command name.

Access the monitor online help for each command by typing help <command>. The full 
command name must be entered to access the online help.

In the following command descriptions, Courier New font is used to show the command 
format. Square brackets [] enclose optional arguments, and Italic type indicates that you 
must substitute your own selection for the italicized text.

The boot commands provide facilities for booting application programs and operating sys-
tems from various devices.

Execute the command stored in the “bootcmd” environment variable.
