The NVIDIA 50-series Blackwell cards require the use of the new open GPU kernel module, but several of NVIDIA’s older generations of GPUs - including the Maxwell, Pascal, and Volta generations - lack the GPU System Processor (GSP) module on their silicon in order to leverage the open kernel module, and thus will no longer function. This includes the GTX 700-series, 900-GTX series, GTX 10-series, the Quadro M-series and P-series, and Tesla M-series and P-series cards.

Here’s the detail. Sounds like the support for the new cards messed up the old cards, but it sounds like they might be working on a comparability fix. I use open drivers on some other systems. I don’t remember why I didn’t consider that a option here. This server has lived many lives and it’s mission continues to change and refocus all the time. Thanks for the reply.
