Here's a small preview on the Flash utility for the Zeus68k card. You'll use this tool to upload Kickstart and Expansion ROM (AR3, AT-Bus 2008) images to the onboard flash ROM.
It's been a while since I last did some serious Intuition coding, but I'm quite satisfied with the result.
The program requires Kickstart 2.x to run, because it requires GadTools and ASL system libraries. We have a CLI utility for 1.3 users, which should be enough to get a 3.1 ROM ready for action.
Currently the software supports 256k and 512k Kickstarts only (256k ROMs will be doubled to 512k automagically). Support for bigger ROMs will be added later, they'll simply occupy more than one slot.
