M55 (8807-93G) CPU Upgrade Error Message: 167 no processor bios update found

[Calvin7_de]

Hi all,

I am trying to update the CPU of my M55 (8807-93G) from
Intel Core 2 Duo E6300 (1.86Ghz) to Intel Core 2 Duo E7600 (3.06 GHz).

The Bios does recognize the new CPU very well but when booting the system it stops with the error message:
167 no processor bios update found

Unfortunately I didn't find the right solution on the internet. I flashed the BIOS to the last patch (12/12/08) but the message stays the same.

Lenovo offers a BIOS patch from 16/01/09 but in the end it's from 12/12/08.

Any Ideas? Can I use another BIOS?

Regards,

Calvin
