So no possible way? I mean the sockets are exactly the same, FSB matching at 533 mhz. I mean there must be some discernable way for it to boot up with the CPU
You didn't check the chipset support?
That could be your issue. If not, then it is the bios that is the issue. Either way, there is nothing you can do about it. You can't flash other bios's and I wouldn't recommend it even if you could because of the high risk of bricking your computer.
