- I know I need a WB_2.x: partition. Can this be the only partition, or would I simply make this a small partition and have a standard DH0: partition along with it?
I guess so - afair you can call the partition DH0: and set WB_2.x as the label. You can run 3.x from it as well (provided there's a 3.x Kickstart file).
- Do I need a WB_1.3: partition if don't want to boot to 1.3?
I don't think so.
- I know the Super Kickstart files need to be in WB_2.x:devs/kickstart. I assume "kickstart" needs to be a drawer containing the file? If so, does the filename matter? Or is the file actually called "kickstart" and located in WB_s.x:devs?
Nope. The filename needs to be "WB_2.x:devs/kickstart". The 1.4beta "boot ROM" is pretty dumb.
