Just got this motherboard and after I setup the BIOS with the settings I want I can no longer access the setup program. When I hit <DEL> on bootup, the floppy drive light comes on and stays on and I just get a blinking cursor in the upper left corner of the screen. I did flash with the latest BIOS from ASUS. The system will boot normally, just can't get into the setup. I have to clear the CMOS to get back in. Any ideas what setting in the BIOS might cause this? Thanks Dave
