A1200 kick 3.0 >4GB disk support

is there a way to use the second partition with kickstart 3.0 and WB 3.1?

The way to go here is to extract the scsi.device from the amigaos rom update file of your 3.9 installation, copy it to the boot volume along with loadmodule and then use loadmodule to make the new scsi.device resident.

i simply use setpatch from 3.9, seems to work fine.

That is also an option (you need the rom update file too). Eats more RAM though.
