Boot with unsupported CPU

Specs: Windows XP, 2.8ghz
Hi, i recently bought a Asrock 4Coredual-sata2 motherboard and thinking about getting a E7400 to go with it. Unfortunately, i don't believe the bios version supplied with the motherboard offically supported the E7400 but can be updated to do so. The question is whether i can get the system to boot with the E7400 so that i can update the bios to support the CPU?

What specific Asrock motherboard do you have and what Core 2 duo cpu's does the board support? My guess is that you will probably be able to boot up, but it would be helpful if you supplied more information.

the model is 4Coredual-Sata2 rev 1

Cpu support list is here.

The issue is that i think my board has a P1.60 bios as indicated by the sticker on the bios chip itself. hence the E7400 CPU isnt yet supported but just needs a bios upgrade.

not an exact answer to your model of mobo,but i do recall working with some IBM computers from early pentium 4 socket 478 days and when upgrading with a newer faster processor it would hang for a while on POST screen and then say something like NO PROCESSOR ID FOUND, PRESS F (something) TO CONTINUE. you could then use the PC but every time you switched it on it would do the same thing until the BIOS was updated with one that correctly recognised the cpu.

If you just bought the board brand new, it seems unlikely it would have such an old BIOS as P1.60. Then again, it may have been sitting in a warehouse or on a shelf for a LONG time. If it's a used board, it's more likely to have an old BIOS.

If you install an E7400, the board *may* boot & simply recognize the CPU as an "unknown processor"...then again, it may not boot at all. I suggest you contact ASRock tech support.

If the board doesn't boot with the E7400, you could try to buy a really cheap cpu(like the Celeron) and install it so that you can boot up and change the bios. Of course, that might be more trouble than it's worth.

I have found in most cases bios support is not a show stopper. It most likely will boot to the flash program. In all the times I have tried. The OS would boot fine. NT would complain but work.

"Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10

Finally tried it. Detected it as the correct CPU and it does show that it is Bios version P1.60.Works but takes ages to finally POST. Updated to latest firmware to solve that. Thanks everyone.
