Hi everybody, Sorry for raising the same question again. Since there is no reply to my last post, may be I have not given enough details for my situation. I have observed the following two error messages from the log file: (WW) RADEON(0): Bad V_BIOS checksum (WW) RADEON(0): [agp] AGP not available Does it really matter? How can I fix it? I am using Radeon 8500 with P4S8X mother board. When I test my system with screen saver required GL, the performance is deadly slow. Any help? Thanks. _______________________________________________ xfree86-list mailing list xfree86-list@xxxxxxxxxx https://listman.redhat.com/mailman/listinfo/xfree86-list IRC: #xfree86 on irc.redhat.com
