I noticed on Asus' site that they listed the 404 (haha ironic name) bios.

Aside from the bios there are a couple chipset driver updates -

- Intel(R) Matrix Storage Manager Driver V7.5.0.1017
- Intel ICH9 RAID Driver Disk Version 7.5.0.1017

The drivers have been out there for a while but I haven't updated. Do you folks get your chipset drivers here, at Intel site or elsewhere?
