Dont be stup. How can you load hack bios before the original bios if you depend on the dashboard to load it
Orinal Bios => dashboard=> Phoenix bios=> dashboard, ava, evox, any
only with a modchip
Hackbios =>dashboard=>, ava, evox, any

Get it what you are saying it doesn't make any sense. If it does, I don't really know how can you load a hack bios from the beginning without a modchip and without getting into the error screen.
Unless you have found the way to upgrade the xbox originals bios with a hack bios.
Have you ?
