I've had to do this, too. I think that there may be bug-prone floppy drives
and controllers out there. One occasion (linux install), replacing the
controller *fixed* the install problem -- I believe it would boot
DOS, though. Definitely a bum controller, though. I seem to kill a lot
of floppy controllers -- don't know why :(

My two cents' here ... I've had great "first shot works" installs of
NetBSD i386 on some really funky old 386SX hardware that wouldn't even
look at a linux kernel, for example...
I have had two failures to date:
1) The Disk LBA/CHS blah blah described in another just-finished
thread, which problem I intend on assaulting later this summer. The other
related threads have been quite valuable.
2) Trying to do an install on a 386SX with a 1.2 MB floppy. This
would boot partially, then complain. Putting in a 1.44 floppy drive
(hmm and a different controller) and re-dding the install kernel and
fs cured everything.
These were the release 1.2 version install thingies (kcoth12, inst12),
obtained earlier this year (May?).
So my question is:
Did I do something really stupid with the 1.2 MB floppy and
think that the 1.2 in kcoth 1.2 (and the size of the images :) meant
1.2MB floppy, too? I.e. is there a set of 1.2MB images I overlooked? I
wouldn't mind having these, if they exist, as a backup of last resort.
Has anyone gotten a 1.2MB floppy NetBSD 1.2 to install?
These are really academic questions... since a 1.44 MB drive can be had
for nearly the cost of postage. (used, working ones = US$8 or so).
Unrelated: Anybody seen/heard from Brian Hechinger lately?
(wonko@arkham.net)? Used to be on this list, but seems to have
vanished.
