549 help
550 If you say Y, the OpenPROM device tree will be available as a
551 virtual file system, which you can mount to /proc/openprom by "mount
552 -t openpromfs none /proc/openprom".
553
554 To compile the /proc/openprom support as a module, choose M here: the
555 module will be called openpromfs.
556
557 Only choose N if you know in advance that you will not need to modify
558 OpenPROM settings on the running system.
