This option I noticed while reading the man page for mkbotdisk. I 
assumed the default would be for a 1.44 (or 1474560 :-) ) floppy.

Good pointer.
I tried this command and it worked like a charm. It even added an icon 
on the desktop for the loop mount.

I am glad that I wasted a disc (given to me anyway) to make the CDR with 
the below options. I booted with the burned image and found that I lost 
my tapping feature for my laptop. I assume that you would have to type 
in the magic incantation during boot to get tapping to work, when 
booting from iso or floppy.

Your true value depends entirely on what you are compared with.
