the easiest way is to by a recovery tape from HP. that what we did when we
got the 822S.  i may/will make others in the future, but that one should allow
us to at least boot from the tape.

the other approach (IF you have a couple of spare sections is to build
a second bootable disk  I used LIFcp and make a bootable section6 on my old
7937.  after ripping out /usr (and the usEr areas) I made a second root on the
the 7937.

the boot ROM by default loads and boots to the 2200, if it crashes,
i can boot to the 7937. This was tested by undoing the cabling to the
2200 and booting to the 7937.
