There is, but you have to ask Michael Boehmer really nicely and then he might be able to help, but you need to send it away to be flashed. He's on the forums somewhere (certainly on other Amiga sites, probably here too), usually under the monker mboehmer_e3b or something I think.
Even then though it won't work in OS 4 (which is why in the end I didn't bother).
