No special mapping necessary.

We have installed (~ 4 weeks ago) a Xenix system with a 170MB ESDI drive,
which had 1224 cyls.

Just set it up in the dkinit for 1224 X 7, and it works fine.  I have
_disabled_ the BIOS ROMS on the controller, so I know that it is not doing
any remapping or other "funny stuff".

Works like a champ.
