The key will work fine anyway there are no Gigabyte Windows 7 OEM SLP keys Posted as yet. and yes Keys are not Brand Specific.
If you used both the Gigabyte Slic2.1 bin and certificate from Win 7 & Server 08 R2 SLIC 2.1 Bin Collection to mod your bios. Then either compaire it against certificate in OEM folder you downloaded or just replace it with the one from Win 7 & Server 08 R2 SLIC 2.1 Bin Collection.
ok got that i'll replace the certi from the OEM folder.. But one question remains unanswered, Will Windows 7 ultimate be Activated or Some other?? Is the Version to be Activated Key Dependent or SLIC Dependent??
