Apparently all DOS 3.5" floppies are FAT format
with the capacity
is 1,457,664 bytes, regardless the version, after accounting for the
two hidden files, so...
Is there a way I can patch or debug the floppy after generic
format to make it look bootable?
I thought there was a Format /b switch to set a floppy as bootable (which
is different then Format /s which sets as bootable AND copies system
files). Of course, I seem to recall that as an option with DOS, so I
don't know if it is an option with something higher. A quick look in
Win2k doesn't list /b as an option (or /s, and neither seem to work when
tried).

Because the isn't DOS beneath Windows 2000. Windows 2000 runs on the NT

how hard you try. There were rescue floppies for NT, but AFAIK they only
got you around a FUBARed boot sector and first stage loader - loading
the kernel from harddisk.
The last DOS + graphical Shell combination sold as an OS by Microsoft
was Windows 95/98/ME. Windows 2000 and XP are descendants of Windows NT.
Yes, you can still get a command line in these, but it is cmd.exe, the
NT (and up) commandline shell. Old DOS programs keep running because
they are handed a simulated DOS environment. Or they won't run because
the NT kernel flat out refuses them direct access to the hardware (it
has to, for obvious reasons).
Therefore, the /s and /b switches to format would be meaningless with NT
and up.
The last Windows capable of generating bootable DOS floppies would be
Windows ME..
