Suse 9.0, Geforce 4 ti4280 and AGP 8X

Hi all, it's my first message in this mailing list, please excuse my English. I have a problem with the Suse 9.0: I have a Geforce 4 ti4280 (AGP 8X, used driver version 44.69 and 43.63) installed on an Asrock K7S8X motherboard (Bios rev. 2.20, the last available). When I set the AGP mode at 8X, Suse hangs up at the graphic login and I cannot boot the system. Everything works fine (AGP 8X and the same bios settings) with Windows XP professional. Is it a known problem? Thanks in advance! Regards, Andrea Gavazzi. -- ICQ: Mr. Jingle - 39514837 http://spazioweb.inwind.it/andrea_gavazzi
