OK, so you have to use one of the other options.

You can TSOP flash without a game - just solder the points, then boot your Xbox into the softmod, and use Evox to flash your new BIOS to the TSOP chip.
The TSOP and a modchip are just holders for the BIOS. It's the BIOS that allows you to run unsigned code.
I'd seriously recommend that you try the Frosty/xman954 VGA solution first, just to confirm that your wiring is correct.
