several Celsius R550 Workstations are in use at our institute, partly for GPU accelerated computing. Thus, we changed the standard NVidia Quadro Graphic cards in some of the R550 for high end graphics processing cards supporting CUDA. This did not make any problems until we tried graphics cards based on the new NVIDIA GF100 chip, used on Nvidia Geforce GTX 480, GTX 470 (both of which we have tested) and GTX 465 (not tested yet) cards.
We updated the Tyan D2569 mainboard to the newest available firmware on the FSC support website (which is v1.06), but still, when using these graphics cards, the system does not even get beyond the Bios Quick Boot LOGO. That means it is not even possible to access the bios itself, the system just hangs at first image displayed. We tested both cards on one of our rare R570 workstations, where the system booted flawlessly.
I already tried to acquire a newer version of the Tyan mainboard bios on their website, especially since there are already fixes for non working graphics cards in the version history of the available bioses. However, Tyan does not even list this mainboard on their website.
Any suggestions of how to solve this issue are very welcome.
