BUT - no partition table on the disk
I haven't tried to access MS-DOS floppies from a *n*x
system for a long time.
Also, floppies donrCOt do partitions.
Two things. First I never heard bout that. But most importantly, I
never considered that possibility as long as I used floppies. I was
always wondering how I could use as few floppies as possible to put
my files. I was always on the way to partition my files to manage
to put hem on floppies. Never on the way to partition floppies.
At the time I used floppies, if anyone asked me how to partition
them I would have wondered. Why on earth would someone want to do
that? There are many floppies, they can't store anything relatively
big and they take ages to format. To take time to partition them
and to format each partition just to have less space available is a
wonder to me. If you want a technical chalenge, why not, but in
real life: what for?
Well, partitions can be used for "organization"
purposes, which can be useful.
Partitions were only loosely for 'organization' in the MS-DOS days.
Their primary purpose was to work around MS-DOS and early windows
(which was a shell above MS-DOS) disk size limits. Hard drives grew in
size faster than MS-DOS was updated to handle the larger sizes.
Remember too that floppies held rather a LOT of data - by the needs
and standards of the time.
While you can partition them, I very much doubt doing so in the MS-DOS
days would have worked. DOS would have been very unlikely to have
assigned drive letters to floppy partitions. More likely, it would
have either refused to access the floppy, or just merrilly overwrote
the floppy as if it were never partitioned.

Either, I implemented a BIOS upgrade that could use 2k sized sectors instead of 512k , and increased hard drive capacity to IIRC 128Mbyte.
Silly rabbit. 32 megabytes ought to be enough for anybody.
