I've never tried it with my NetBSD system, but I recently brought a
junk-box PC on line with an EIDE drive running Linux; this was using a
controller with on-board BIOS, which safely gets it through a DOS boot
without installing some goofy driver. Of course, sane OSes like your
average Un*x have no trouble with real gemotery, so does it matter?
I remember where a part of the NetBSD INSTALL doc mentioned setting up an
EIDE drive with identical geometry to the way DOS sees it. Is this
actually critical? If so, it might be a good idea to offer the user a
choice on getting BIOS-specified geometry.
