Well here is my situation tonite. We installed a p4 2.26ghz, used his hard drive with Windows ME on it, and it came up fine. We looked at the bios with cpu-z, and it stated that it was mv85010a.86a.0057.p20 which is a higher version than the intel website says you need to support the p4 2.8 533fsb processor. We downloaded the most current bios...p25, installed using the windows bios express installer, and booted the 2.26 again...rechecked the bios and it indeed had updated to the p25.
Reinstalled my 2.8, booted, and ended up with the same result. Black screen....his boot bios probe tool indicated a 99 ( he is not sure exactly what that is until he finds his manual..but it is not good.
Rebooted with the 2.26, and the tester shows the system led changing codes...which he says is what is supposed to happen.
Went back to the intel bios download page, and installed p23...one that is specifically for the d850emvr. Same results.
All of the documentation that I read on the intel website indicates that the 2.8 is supported if you have at least bios version p15..this one started at p20, and went to p25, and back down to p23. No luck.
The company I bought the processor from say that the fact it won;t work with my board is not a legit reason for returning...so I am stuck with a $180 albatros.
I really want to figure out what is wrong...and fix it, so that I have the speed and features I paid for....
Any other suggestions?
