SS_Dave, thanks for the info!
The goal is to expand HDD and just load it with games. I had a chipped Xbox growing up and it's only recently packed it in. Can you dual-boot with the TSOP flashing? Or is that a function of a modchip? I'm not real worried about doing it, more so just curious. I've seen other mods for wifi adapters/HDMI that I'm keen on trying, but that's down the track. Where do you purchase your chips from? I've only been able to spot them in eBay and none provide much detail haha.
