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.
