My bootsector is clean, and it is /highly/ derived from the *FreeDOS* 
bootsector (GPL). If you take the FreeDOS bootsector and mine and look 
at them side by side you will find some striking similarities. I have 
complied with the GPL and put the derivative work under the GPL too. I 
haven't been able to get a dev to look at it yet. If any who fall in 
that category want to, I'll send it to you.
