Lute -
If you have a large enough EPROM (typically around 32K), you can burn the whole
mess into EPROM. Most coco's are setup with 8K ROM slots though.
The thing that causes /D0 to be read is the preboot (part of track 34), and
then the Boot module. When the Boot module completes, it hands off to Os9,
which in turn runs Sysgo, CC3Go, or whatever is specified in the Init module.
The Init module also controls who the Root directory will be at startup, so
this is the place you need to tweak for HD startup.
Once you have customized your INIT module, cobbled a bootfile, and burned it
into ROM, you can do what you like.
