Loader Quick Help
-----------------
The boot order is PCMCIA or floppy -> Flash -> Disk -> Lan ->
back to PCMCIA or floppy. Typing reboot from the command prompt will
cycle through the boot devices. On some models, you can set the next
boot device using the nextboot command: nextboot compact-flash | disk

For more information, use the help command: help

Hit [Enter] to boot immediately, or space bar for command prompt.
