Well, I thought "ded" was an os9boot file editor.  Never mind.

So, I merged os9boot and my drivers onto another disk, deleted 
/dd/os9boot, then copied the new os9boot file over to /dd, ident 
os9boot shows my drivers, but after booting up, the 3 drivers are not 
in RAM.  This leads me to believe that fragmented os9boot files are 
not supported, and the load process breaks.  I thought NitrOS-9 
handled this.  The file is still at sector $0B.
