If you bought some awesome accelerator with IDE for your CD32 maybe you miss the cd32's boot screen like I do. This util recrates the boot screen and gives you options to -load wb or -boot cd. You can select what you want with your joypad(up/down - fire). There's also 10 secs of a countdown. If you don't press anything it'll loadwb. Load WB simply ends the util and continues your wb startup-sequence. Boot CD simply resets your cd32. So you should first insert CD you want to boot and than press fire.
