Thanks everyone for the replies. Still I miss something.
I'm trying to make the NetBSD installer floppies for a
Sparc 2, sun4c according to instructions here.
ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0.2/sparc/INSTALL.html#Installing%20NetBSD%20by%20using%20the%20bootable%20floppies
The relevant section is quoted below. These are the file sizes.

-rw-r--r-- 1 peter peter 1474560 Jun 30 08:17 disk1
-rw-r--r-- 1 peter peter 1530843 Jun 30 08:18 disk2

More specific questions.
1. Why is disk1 gzipped while disk2 is not?
2. How can disk2 of 1530843 bytes ever fit on a floppy of capacity
1.41 MiB (according to Wikipedia)?
3. Can the NetBSD commands be adapted to work in Debian? How?

Thanks, ... Peter E.

"NetBSD and SunOS use the same commands. First, get two 1.44 MB floppy
disks and format them either using the fdformat(8) command or a PC.

# fdformat

Be sure that the `fdformat' command completes successfully before
proceeding; on NetBSD success is a string of all `V 's', and on SunOS
success is a string of `. 's'.

Next, transfer the two floppy images (installation/floppy/disk1.gz and
installation/floppy/disk2) to the disks you just formatted. You can
do this step from NetBSD, SunOS, or a Windows machine using
rawrite.exe (available in the NetBSD/i386 distribution). Insert the
first floppy and run the following commands:

# gunzip disk1.gz
# dd if=disk1 of=/dev/rfd0a bs=36k
# eject floppy

Insert the second floppy and run the following commands:

# dd if=disk2 of=/dev/rfd0a bs=36k
# eject floppy
