Hi, Have recently purchased a Geforce 6600 AGP card but I'm having issues with it and so one my fix options is to look into my CMOS Advanced Chipset features and make sure the AGP aperture size is set correctly... the only problem is I can't seem to get to that menu. I press F1 to access BIOS upon boot-up but this goes straight into the stnard BIOS set-up menu and I can't get beyond those options to find my way to the CMOS set-up and the menu I need. I have looked at my mobo manual and it says those menus are there but doesn't tell me how to get there. It seems that there is a menu that should come before the one that does appear but my system doesn't use it. Looking on my mobo maker's site says that I should press Delete when powering-up which I have tried but no luck either (I've tried this in combination with F1 and without). Anyone have any ideas on how I can get to the CMOS main menu? My specs: PC: Formally HP Pavillion 491.uk - now rehoused Mobo: FIC VI31 Bios: 3.12 Bios Core: V6.0 CPU: Intel Pentium 4 @ 2.2ghz RAM: 1024mb DDR SD 2100 Any help is much appreciated.
