Answer is Yes, there are BIOS settings for Date, Time and AGP 4X
To get into BIOS update - press Delete key while booting
Date/Time setting is in Standard CMOS Features
AGP 4X setting is in the Advanced Chipset Features - about halfway down the page - make sure AGP 4X Mode is set to Enabled.
I don't know much about your vid card, but I just read that it doesn't support 4X, so you may have to set it at 2X
When in doubt RTFM
(read the fine manual)
I hope all goes well with this MOBO - so far, it's been very smooth with my install - the price is great - I may order a couple more.
Mail me if you have any more issues/questions
