Thanx to everyone for their help in getting my Xbox mods running; both my V1.0s are now functioning properly thanx to doing the pinheader installs. I had originally done a Xapt3r install on both V1.0 motherboards with no luck on either; they kept fragging. But after doing the pinheader install, everything works fine. My guess is that there is some unsolved issue with the Xapt3r install on the V1.0 board. I had also installed a Xapt3r & X3CE on my V1.4 Xbox without a problem, so my experience is that it must be a glitch with it on the V1.0. So, I highly recommend doing the pinheader install not only on the V1.0 Xbox, but on all version motherboards. In the end, it will usually save you time, money & a lot of grief. Just thought I'd write this up to help out anybody with a similar V1.0/Xapt3r frag problem. Hope it saves you guys some trouble. Good luck & good gaming!
