Xbox Debug Kit: Hard Drive Upgrade?

[GoTeamScotch]

I recently acquired a broken Xbox Debug Kit and after some troubleshooting, I fixed it by replacing the hard drive. The old drive is apparently dead and I may come back to trying to resurrect that somehow to see its contents. But in the meantime I've swapped in a standard 10GB seagate drive in its place, ran the recovery tool, and things are working fine now. I know only debug BIOSes will run on these X2 MCPX motherboards, but are there any hacked debug BIOSes floating around that have LBA48 support for hard drives greater than 137GB?

There is a modified xshell.xbe to support F drive. There is also the Yoshihiro modified debug bios that has LBA48 support.
