Boot Manager Variables

The boot manager stores a number of variables in non-volatile memory. You
must be in BOOTMGR[x] mode. You can set and view most variables from
the boot manager prompt. The variables are:
Boot manager revision—The version number of the boot manager. You
cannot set this variable from the command line.
Autoboot—If autoboot is set to no, the IP500 Series appliance stops at
the boot manager command line during the boot process.
If autoboot is set to yes, the IP500 Series appliance does not stop at the
boot manager command line during the boot process. It does wait for the
amount of time specified in bootwait for input from the keyboard. If
input is received, the boot manager goes to the command line; otherwise,
it proceeds with the boot up.
Factory default: yes
Bootwait—The amount of time, in seconds, the boot manager waits for
input during a boot up when autoboot is set to yes.
Factory default: five seconds.
Boot-file—The name of the file to use as the operating system kernel.
Factory default: /image/current/kernel.
Boot-flags—The string of flags that is passed to the kernel.
Factory default: -x
