Bios Mods -The Best BIOS Update and Modification Source

I think this by looking at this notation

[We have modified bios and enabled 4 cores]

"" 4) (for for Core 2 Quad) Activate all four cores:

Edit: With the original mod - BIOS from xiafei 290 @ 51 nb.com, it was needed to load a modified APIC table with the acpi command from the GRUB 2 bootloader, with otherwise core 2 and 3 would not be activated (only core 0 and 1) .

Flashing the modified BIOS-files with the quadcore APIC table is sufficient Credit to highsun @ 51nb.com who made these mod - BIOS - files.
They are linked here: http://www.thinkpad-forum.de/threads/172581
Some of them can also be undervolt the APV table (for use with dual cores).
There will be an error message about wrong checksum while flashing them. This is normal. Ignore it and proceed with the flash.""

If I flash the mod bios you sent, will 4 cores be active?  

thankyou

I don't think so. But you can try.

I succeeded in updating successfully, but only 2 cores work

(On bios it recognizes 4 cores (before updating and after updating))

I do not know how to try it
Please tell me how to do it
Thank you

I don't know too...
And I haven't any knowledge's about editing APIC table.

ok...
If I tried one of these then is it possible for 4 cores to become effective?

""{Core 2 Quad needs GTLREF (which is 0.63 * VCC 1 R 05 B) at pin D 22, which is reserved on dual cores.

""Edit: Here is a much simpler solution suggested by FryPpy, which is confirmed to work.""

I think it will not help.

I will report when there is something good
