Redhat 9 install help-Acceleport 2r XR

Hello,
My 2 port acceleport card is detected on boot up by kuduz (kernal 2.4.18-14) but i seem to be having problems with the install. Is there any documentation for Redhat 9? Can anyone provide me with a step by step install. I’m also new to linux so any advice would be greatly appreciated. Thanks
