Got the biostar tforce 6100-939 in my main rig. Absolutely love the board, overclocks well and is rock stable.
If you are installing on a single SATA drive you do NOT need the Nvidia raid disk, just turn the raid off in the bios and it sees the SATA ports as standard IDE ports 5 and 6.
I use the latest Nvidia nforce drivers for this chipset from the nvidia website(version 8.22), using latest bios from the Biostar website.
If you get any probs, either post in thread or email at my trust email address
