On i386 (really PC/AT clone), NetBSD might be installed in FDISK
partition ("slice" called by FreeBSD people).

	partition "d":	whole disk drive
	partition "c":	NetBSD using area

In this case, NetBSD shouldn't modify or rely on other than the
partition "c" (exception is fdisk(8) and MBR).  Since bad144 remapping
is valid only for NetBSD, it should be complete in NetBSD using area.

Yes, scsictl(8) is your friend.  :-)

I agree.
