A7M266 MOBO FIXED!!!!

He was my problem:
Its a bad, bad thing

Solution:
After I tried everything (5 hours troubleshooting, including purchasing another processor), I took one last look into my motherboard before taking it all apart and shipping it back. I happened to look at the "USB device wake up" Jumper. I never bothered with this jumper before because I do not use USB, and have absolutely NO intention of using the device "wake up" functionality. Default (which is where I left it up until now) is set to +5v, and there was a jumper to set it to "+5vsb" (no idea what that means..). So on a whim I decide to change the jumper. I reboot my computer and it works flawlessly, a STABLE 1Ghz working at 266mhz FSB!!!

I have no idea why Asus would ship a motherboard in a DEFUALT configuration of USB that is UNBOOTABLE. The only thing I can think of is that with my setup, the +5v line was very loaded, and the USB sitting on that line was making my system unstable, hence switching it to a +5vsb?..just a guess.

THANKS to EVERYONE who offered advice and opninions 🙂
 
I am also having a boot problem with my A7M266 and did try and rejumper the USBPWr1 to pins 1&2 vs 2&3.

The system generally starts OK but restarts, it goes off into never, never land. Video stuts down, must use a system reset to get it going. I think it is a BIOS setting, but what???
