I have a Lenovo T61 with Vista Business 32 on it. I have looked at the SLIC table with ACPIScope and compared that to the LENOVOTP-7L SLIC dumps in the forums (my BIOS is of the 7L type). Looks like the bytes at 0x18 and 0x19 are different in mine. I also remember using an application before to test out an install for Vista Ultimate (I do have the CD and I am the legal owner, so no piracy comments please). But after that point, I cannot self activate the Vista Business installation using the retail 32-bit Vista CD and the slui import/arm method. I get a "connection needed to the Internet" error. Questions: Do the bytes shown above in the SLIC table describe the type of product (Vista Home Basic, Home Premium, Business, Ultimate, etc) the cert is allowed to activate? If I change the values back to what is shown in the 7L dump, should I be able to self activate Vista Business again?
