I remember that, used track 128 of the os9 filesystem for the boot track. 
Worked when it wanted to but also had a problem reading the fat, getting 
a sector full of zero's, then scribling all over the drive on a 
subsequent write.

Msgs to Chris were never answered, a new controller card behaved exactly 
the same, and I eventually got tired of fixing the filesystem again and 
again, and bought a 4n1 from Tony, fixing that problem but not the 
clock, however I was able to fix half the clocks problem eventually. The 
half I couldn't fix was the scrambling of its setting by noise during a 
reboot. But a decade later that drive got sticky, and a TC^3 came to 
live in slot 3, driveing 2 of my old amiga 1 Gig drives.

It should be Bill. There is not any self modifying code in Nitros9 that I 
know of.  The boot module would have to know about itself, but 
everything else s/b fine.
