Do you have spare processors to use or anything? Or do you have other ways of updating it? Yea, when I first saw your posts and profile you do look like a good person and what not, it's just the whole random person on the internet kind of thing, plus im new to the forums. By the way, do you charge people to do it?
at any given time i can have a half dozen processors or more, just depends on what day of the week it is. you don't even want to know how many motherboard boxes i can see in my place right now from where i am sitting. even if i don't have a batch of CPUs i am going through, i will always have my golden little E6600 that can get a BIOS updated on that board no problem.
no charge, just keep it in mind next time you have the opportunity to help someone.
in the end, you likely will be able to POST and run the system with the E6750 like jdrom17 said, but if you don't get POST...i got ya covered.
Ah alright. I have helped people in the past with computer stuff, not really with anything physical though, just helping them find which parts are compatible and what not. What do you think the chances of it working without the updated bios are?
