I never belived the epsilon bios thing, but it could have been run with the mod chip. Part of what makes the chip tick is a custom boot code that does not have the ipl checks that the biult in chip does. Basicly, if devhook can run it, the mod chip can. But the epsilon bios is still almost defenalty a fake, and untill someone cracks the ipl code, there will never be non-modchip custom bios's.
--afterthought--
I think it's possible to mod the ipl loading code. This is what alows us to downgrade from 1.5 to 1.0. But still, this is encrypted and untill it is fully cracked, there will be no custom f/w's.
