O.K., Brand new build using Intel i7-860. First off, love the system! One glitch – Zune 30 causes VERY slow POST and performance problems if I boot with the Zune device connected. Once in Windows, 2D graphics benchmarks 3X faster, but system is unstable and slow. Normal boot and performance without Zune attached.
ASUS graciously replaced the mobo, which solved an Express Gate problem, but the Zune problem has not gone away. All other USB devices play fine.
Windows 7 Professional 64 bit

Note – Problem begins during POST when Zune is attached, so it’s not an OS problem. Suspect a conflict between the Zune and the Sapphire Radeon HD 5770.
Anybody else having similiar problems? Anybody found a solution?
I can't see anything in that diagram that would make you think that, the opposite if anything. What are you referring to?
It sounds like you replaced the board with the same model so that's not really trying a different board. It just means it likely wasn't a manufacturing error specifically involving the first board.
I think you are on track. More investigation reveals the Intel P55 Chipset, as released, has had BIOS problems with with iPods as well. Gigabyte appears to have their BIOS fixed. Asus said to try them back in mid January. By the way, loaded Dec 9 BIOS for this mobo and it is much more stable. Will test the Zune problem on next boot.
Asus is on the right track with the Dec BIOS release, but no cigar yet. Booting with the Zune attached no longer hangs up the POST, but, it now causes the BIOS to lose my boot drive altogether.
Disconnected the Zune, reassigned all hard drives in the BIOS, and the system came back on fine.
BTW - Somewhere after the new BIOS install, one of the (2) on-board LAN adapters disappeared, can’t manually install it, system won’t find it – It’s just gone, as if it weren’t installed. Tried disabling then enabling it in the BIOS – Nothing.
This brings up another issue – Can’t make the Realtek Teaming work (At least I couldn’t before the second LAN adapter disappeared). This is true for mobo #1 and #2
Did I mention Zune works fine on every other machine I tested it on?
