Rev. 1.1g of motherboard, as far as I can tell. Works very well with Windows 7 RC. All drivers installed automatically during Windows setup, although I believe the Internet may have been required for some. Only minor issue is that one device shows as unknown in Dev. Mgr. I don't know what it is, but I haven't put much effort into finding out.

I am using Adaptec 29160N scsi card, so I cannot vouch for IDE or SATA hard drive performance. Optical has worked perfectly.

Windows 7 RC has been very stable on this board for about 4 weeks.
