to execute a script at boot time. A sequence of RedBoot commands can be entered
which will be executed when the system starts up. Optionally, a time-out period
can be provided which allows the user to abort the startup script and proceed
with normal command processing from the console.     </P

>RedBoot supports the notion of a boot script timeout, i.e. a period of
time that RedBoot waits before executing the boot time script.  This period
is primarily to allow the possibility of canceling the script.  Since
a timeout value of zero (0) seconds would never allow the script to
be aborted or canceled, this value is not allowed.  If the timeout
value is zero, then RedBoot will abort the script execution immediately.</P

On many targets, RedBoot may be configured to run from ROM or it may be
configured to run from RAM. Other configurations are also possible. All
RedBoot configurations will execute the boot script, but in certain cases
it may be desirable to limit the execution of certain script commands to
one RedBoot configuration or the other. This can be accomplished by
prepending <TT
CLASS="COMPUTEROUTPUT"
>{&lt;startup type&#62;}</TT
> to the
commands which should be executed only by the RedBoot configured for the
specified startup type. The following boot script illustrates this concept
by having the ROM based RedBoot load and run the RAM based RedBoot. The RAM
based RedBoot will then list flash images.</P
