I've been using the A7V with the 1003 bios since last Nov. with no problems. Also have Sprint Broadband Wireless and works great with it. I've tried just about all the via/promise build's and have noticed very little difference with them. I just installed the Bios Savior so I can flash to newer bios and try them without destroying my original bios. I just have to flip a switch for which ever bios I want.
