A few notes on using a USB floppy drive with tomsrtbt. I have a YE
Data model YD-8U12 floppy drive. Note that not all USB floppy drives
work with Linux due to violating the USB specs. The YE Data models
work with Linux and Macs.

These notes will not help you to boot to tomsrtbt on a USB floppy. The
YE Data floppy does not support either the 1.7MB format tomrtbt uses
or the 2.88MB format.

Here is how to use it as a storage device once you have booted to
tomsrbt.

First, get the following modules. My preferred way of doing this is to
mount Steve Brown's tomsrtbt ISO image
(http://userpages.umbc.edu/~sbrown7/), and pull them from there. You
need usbcore, one of usb-[uo]hci, and usb-storage. Copy them to /tmp,
cd there, and decompress (bzip -d) 'em.

Put a floppy diskette in the drive and plug it in to the computer.

Next, insmod usbcore.o. Then try the two usb-[uo]hci.o modules. Most
motherboards will use one or the other; if one doesn't work, the other
should.

Then insmod usb-storage.o. That one takes a while (at least on my
ancient laptop). You should hear two different accesses to the floppy,
see a message about "USB mass storage support registered," and get the
prompt back.

My USB floppy shows up on /dev/sda (not /dev/sda1;there are no
partitions on a floppy), yours may show up elsewhere depending on what
SCSI devices you already have when you do this. So I mount it as
follows:

mkdir /floppy
mount /dev/sda /floppy

You should see a complaint about not finding an ext3 file
system. Since what you have is a FAT or VFAT file system, this is
normal. ls /floppy should show the contents of the floppy.

If you want long file names and other Windows 9X compatibility, use:

mount -t vfat /dev/sda /floppy

Don't forget to umount before pulling the floppy diskette.

Enjoy.
