I am now attempting an install via a USB DVD/RW and a Promise eSata controller with the motherboards SATA controller disabled, as I'm pretty sure this is what's causing the issue. I'm hoping that, if it works, I can turn on the controller after the install, and install the controller manually. Then copy the drive to the internal drive, and hope it flies.
Will let you know how it turns out, but ideas in case it doesn't work are welcome.
Well, for anyone interested, it appears the only way to get Win7 Ultimate installed on one of these boards, follow these steps:
Disablethe motherboards SATA controller in bios
Install SATA controller that isn't intel into PCI or PCI-E slot
Hook up another hard drive to the add-on SATA controller
Hook up USB DVD Rom
Install Win 7 to the drive connected to the peripheral SATA controller
Once Windows is installed, reboot and turn the onboard SATA controller back on, to AHCI
Install Intel drivers for onboard SATA controller (microsft installs its own, so you have to install the intel ones over them).
Reboot, and make a rawcopy of drive with windows installed on it to the drive connected to the motherboards SATA controller.
Connect your both NIC ports to network durint installation. After the install completes, install the latest Intel NIC driver. For more details, please see http://www.intel.com/support/motherboards/server/sb/CS-031086.htm
Thanks Edward. That didn't work the first time I tried it.
It did, however, fix the insane hardware interrupts happening after I was able to install the way I outlined above.
