I'm moving this over to help from sparc.  The original request was how to
make install boot floppies on a Sun IPC 4/40 running NetBSD/sparc1.4.2.
(Previously I made them on the same model of IPC 4/40 running SunOS4.1.3.)

All I get is:
# fdformat
Ready to format /dev/rfd0a with 80 cylinders, 2 tracks, 18 sectors of 512 bytes
(1440 KB) Yes/no [y]?y
EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEF
fdformat: 160 track formatting errors

What I've been using on the SunOS machine, namely, "dd if=boot-142.fs
of=/dev/rfd0c bs=512 conv=sync", does make a viable install floppy.  The
bs=18k surprises me (but no way to test until I get fdformat to work).
