For 50MB 50000

count=50000

Before you had bs=1024K and count=50 - I presume I could do the same here.

We made the boot disk (it took a couple of hours to come up with a 
completely good 1.44MB floppy disk - one drive would not format anything 
until we cleaned it, another formatted disks with 1 bad sector as 100% 
good and they would not work with other images such as a 1-floppy linux)
and I will try making the 50 MB fs.img on the zip drive tomorrow and find 
a way to boot to it with loadlin from the baslin directory for practice.
