I have just finished building my new dual Opteron machine. Only\nproblem is that whenever I install the Adaptec 2120S on the\nmotherboard the video dies. Remove the card, I have video.\n\nI am putting the card in PCI4 with the PCI-X jumper set for PCI\ncompatibility and the 66Mhz jumper set for 66Mhz max speed (the max\nspeed of the 2120s).\n\nIt does not matter whether or not the 2120S is connected to the drives\nor not. Install the card video dies.\n\nPLEASE HELP. Both Tyan and Adaptec offered me no help.
