Just a thought on the kickstart disk issue (if it is, I'll try to make a new ADF of my kickstart disk when I can, in case my kickstart.adf is bad).
There's an app PIRU wrote called mkkickwork that creates a combined kickstart/workbench floppy format. I use one of those on my A1000 to load the IDE drivers and transfer control to my IDE controller..
Anyway, not sure if the source code for that might have some clues around the kickstart/kickwork disk format, but PIRU has released the code for it...
Again, not critical, just something I noticed...
Still awaiting some parts so I can try to make a floppy and power cables that I can hook to a switch and choose which device to use..
