I'm trying to find anyone who still has at least ONE (hopefully two) DMS X-B.I.T. chips left for sale. I just picked up another Xbox (v1.4, possibly 1.5), and want to mod it as well. I love the X-B.I.T. - it's cheap, does everything I want, and is really, REALLY easy to install solderless.
To those who say "solderless sux" or that the X-B.I.T. was "unreliable", I personally have a 1.0 Xbox that's been running one for over 4 years now (it has the original X-B.I.T. in it.) My kids have one as well, running for the same amount of time. Their Xbox finally died (fist the power supply, the the mobo went.) I picked up another Xbox, moved the chip & HDD to the new(er) Xbox, and they're done. Took me about half an hour total. Several of my friends had me mod their Xbox's with them as well, no issues.
I really don't want to look into another chip, but I will if I have to.
