I have the following system (notebook):

- Asus A7M (Z83M-7S031C)

- AMD Turion 64 X2 TL-52 (Socket S1)

- 2 Gb. RAM

And I want to upgrade the processor to an AMD Turion 64 X2 TL-68 (Socket S1). In theory this is possible, but I can't find a recent BIOS that's supports this CPU model. I've contacted the Asus support, but they have directed me to AMD. What can I do? I've already replaced the old CPU, but if I start the system I get the message: "Unknown Processor Revision" and "The processor(s) installed in your system are of an unknown revision"

Thank you in advance for any help you can provide!
