You will, of course, have to update disktab and add f2361_sizes[].
You will then find out that the hp.c driver causes UNIX to crash
miserably on any drive that's not already specified in hpst[].
You will go away feeling miserable, and then when you add an
appropriate entry to the end of the hpst[] array, it will start to
work.  You will then probably (as I did) leave it at that until
you have to add yet another odd drive.

I have done exactly this to a 4.2 driver, and then went and implemented
the more general solution in an Ultrix driver.  If you write, I will
ask permission to send you the 4.2, into which I may by then have
retro-fitted the "more general" solution.
