What the others who answered, should have said is;
'rdev -h'
which will produce;
usage: rdev [ -rsv ] [ -o OFFSET ] [ IMAGE [ VALUE [ OFFSET ] ] ]
rdev /dev/fd0 (or rdev /linux, etc.) displays the current ROOT device
rdev /dev/fd0 /dev/hda2 sets ROOT to /dev/hda2
rdev -R /dev/fd0 1 set the ROOTFLAGS (readonly status)
rdev -s /dev/fd0 /dev/hda2 set the SWAP device
rdev -r /dev/fd0 627 set the RAMDISK size
rdev -v /dev/fd0 1 set the bootup VIDEOMODE
rdev -o N ... use the byte offset N
rootflags ... same as rdev -R
swapdev ... same as rdev -s
ramsize ... same as rdev -r
vidmode ... same as rdev -v
Note: video modes are: -3=Ask, -2=Extended, -1=NormalVga, 1=key1, 2=key2,...
use -R 1 to mount root readonly, -R 0 for read/write.
A perfect example of 'rdev' is when you make a kernel on your machine using
"make zdisk" and it will be used to boot another machine, (Who's drive
architcture is different to yours), rdev allows you to change the root
filesystems location, as described in example 2 above.

They sould do nicely.
