I had to see if it would work.

bunzip2 tomsrtbt-2.0.103.ElTorito.288.img.bz2
mount -o loop tomsrtbt-2.0.103.ElTorito.288.img /mnt/foo
mkdir /mnt/dos/rtbt
cp /mnt/foo/bz2bzImage /mnt/dos/rtbt/rtbt
cp /mnt/foo/initrd.bz2 ~/initrd.bz2
bunzip2 ~/initrd.bz2
(might not need to, I don't recall wether or not the kernel can handle a 
bzip2 image, it can handle a gzipped one though. Anyhow once it's 
bunzip2ed, you can mount it on loopback & copy over any add-ons you 
want to the appropriate place - there's 1700 odd KB of spare space)

cp ~/initrd /mnt/dos/rtbt/
cp loadlin.exe /mnt/dos/rtbt/

Boot DOS.
cd \rtbt
loadlin rtbt initrd=initrd root=/dev/ram0 rw

Works for me. Haven't tested it much though.
