I've got a version 1.1 XBox with a faulty Xecuter 2.6 modchip (there seems to be a cold fault causing the xmas light problem that resolves itself when the box warms up - the box always boots OK when the modchip is turned off).
I've currently got Flashbios 3.0.3 in "one half" of the Modchip and Evox M8 in the other half.
I wondered if there was a way of flashing the internal bios to boot XMBC since I don't play games on it anymore and I just want to use it with XBMC. Is the internal bios the TSOP? If so, is there a straightforward way or guide (and I mean idiot guide - I don't want to brick it) to show how you overwrite this?
