Thanks for all involved with this.
Just patched my first xbox firmware Hitachi 78... had alot of problems getting it into modeb as I bought a cheap ass version of the connectivity kit from diygadget.com. Bit annoyed about that they do say it can "support for debug mode (on some DVD-ROMs)" should have checked deeper as it cannot do hitachi which I found out after alot of stuffing around. They should mention it on the description. Also my fault for being a tight ass and not buying the xecuter kit.
Slax was my savior

Then the firmware mod worked a treat.
Thanks again
Uhmm.. sorry to 2burst" your bubble, but even the original xecuter kit does NOT put a hitachi 78 into mode B... I have it, and it just does NOT do that... you're fine on 59 and below, but for a 78 you gotta use slax....
