+## device is the OpenFirmware device path to the disk containing

+## partition is the partition number where the kernel images are

+## this is usually the same partition number as your root filesystem.
+## so if root = /dev/hda3 (the 3rd partition) then you should have
+## partition=3  This *MUST* be set correct or yaboot won't boot!  This
+## option can be either set globally as shown here, or per image in
+## the image= sections

+## delay is the amount of time in seconds the dual boot menu (if one
+## is configured, by the presense of macos, macosx, etc options here)
+## will wait before choosing the default OS (GNU/Linux or the value of
+## defaultos=).  If you omit this then the value of timeout=
+## (converted to seconds) will be used.
