I think you could rip out your Kickstart ROM and the system won't notice as it's using the Kickstart from flash. You can actually force it to use your real ROM but... hey... that's so slow...
Thanks for the quick answer. Definitely be buying one now that i know that i can boot any kickstart with this baby.
