OFPATH(8)                   System Manager's Manual                  OFPATH(8)



NAME
       ofpath - determine OpenFirmware path from unix device node.

SYNOPSIS
       ofpath [ --debug ] [ -h|--help ] [ -V|--version ] FILE

DESCRIPTION
       This manual page explains ofpath, the utility used to find the
       OpenFirmware device path corresponding to a unix device node, such as
       /dev/hda2.

       ofpath will work on NewWorld PowerMacs only if yaboot is used as the
       bootloader.  It will not work on NewWorld macs booted with BootX.

       ofpath will also work on some OldWorld PowerMacs. Unlike NewWorld, it
       will work on BootX-booted OldWorld machines. Note that OldWorld support
       is not well tested and may not give accurate results.

       Ybin(8) uses this utility to automatically convert unix device nodes to
       OpenFirmware paths as needed.

OPTIONS
       --debug
              This option causes ofpath to output some boring details useful
              only for debugging ofpath itself.

       -h, --help
              Print out usage information and exit.

       -V, --version
              Print out the version number and exit.


BUGS
       Ofpath may not accurately find all SCSI devices, and does not support
       all SCSI adapters/drivers.

       Ofpath also does not support all IDE devices.

       Ofpath does not support IBM hardware.  Send a tarball of /proc/device-
       tree along with /proc/cpuinfo to <erbenson@alaska.net>

AUTHORS
       Ofpath is based on show_of_path.sh written by Olaf Hering, it was
       rewritten to work with /bin/ash and stripped down systems such as
       boot/rescue floppies by Ethan Benson.  This man page was written by
       Ethan Benson.

REPORTING BUGS
       Report bugs to <erbenson@alaska.net>
