Major success here!!

After a grueling 3 hr session (I have a 7 month old baby around and had to stop every few seconds) of soldering each pin onto the LPC, one by one, I finally got the v1.0 XBOX to boot!!!

The old drive appears to be completely toast, but that really doesn't matter. I am prepping a new 120 GIG Maxtor for use.
Now, the ONLY question I have left is this.
I want to FLASH the TSOP that is onboard of the 1.0 so I can pull the DUOX2 and put it back into my 1.6.
Would it be easier/better to use Slayers 2.6 disk to FLASH the TSOP on the 1.0?? Or use the MechAssault procedure?
Also, for whichever one I use, will it know to go to the V1.0's TSOP rather than the DUOX2's bios??
Finally, what would be the best bin these days to FLASH a v1.0 'Box??
Many thanks to all who helped. It was really appreciated
