I've been running flawlessly with an AMI modded bios with Lenovo slic 2.1 (made from the AMI tool posted here). Always passed WGA. Now after attempting to download the XP Mode tool, it forced me to install WAT -- thus resulting in not genuine. How is WAT determining that I'm not genuine? Is it my bios mod? I've modded the bios again, this time with an ASUS bin and ASUS cert ... no luck ... still not genuine. The removeWAT tool does work for me for the time being, but I would like to try to get back to where I was before, where it believed I was OEM. Can someone kindly point me in the right direction so I can better understand as to if the problem lies in the bios mod itself? Thanks.
