Kickstart (the proper boot ROM) was finished. So, instead, it has a
small stupid ROM that is only smart enough to load Kickstart off
floppy. Once Kickstart is in the WOM (Write Only Memory :) (the
1000's special RAM where every other Amiga has ROM) it takes over and
boots Workbench normally.
Amiga 1000 fanatics will tell you this is a feature, not a bug. :-)
Indeed, the 1000 port of OSK took advantage of this to load *itself*
into the WOM -- even on a machine with no regular memory protection
it's unlikely for the WOM to get trashed.
So even if your hard drive controller doesn't have a built-in ROM, you
may be able to merge the driver with your Kickstart image. If so,
Kickstart should find the hard drive when it scans through all the
drives for a boot disk.
You'd have to bug one of those Amiga 1000 fanatics I mentioned
earlier. I know there's at least one on this list but he hasn't said
anything yet... I have an Amiga 2000, and I don't know as much about
IT as I'd like to. We've pretty much exhausted all I know about the
1000's quirks.

Yeah, I finally got frustrated enough to upgrade to AmigaDOS 2. I
liked 1.3 but the software I wanted to run just wouldn't deal. :-(

The only two CoCO bootable hard drive controllers I know of are the
old Burke & Burke, and SuperIDE.
