[Coco] NitrOS-9 Cobbler Problems

[Joel Ewy]

I finally just mutilated a copy of the Drivewire NitrOS9 distribution 
disk to get my bootable image.  I still don't quite know what went wrong 
in the way I was doing things, especially after I decided to go ahead 
and use the stock mb.dw3 script, other than not booting from the same 
image as the one that I ran the mb.dw3 script from, as Bob suggests may 
be problematic.

But I finally got it to work at about a quarter to four last night.  I 
used to stay up that late routinely, but I'm finding it's not so fun 
anymore...
