In looking for an unlocked BIOS (to enable virtualization) I notice that there are a couple of different GT60s (at least a GT60 2od-261, 2oc-077 and 2oc-022) and I am not sure which one I have. This is what I know: OS Name Microsoft Windows 7 Home Premium Version 6.1.7601 Service Pack 1 Build 7601 System Manufacturer Micro-Star International Co., Ltd. System Model GT60 System Type X64-based PC Processor Intel(R} Core i7-3610QM CPU @ 2.30GHz, 2301 Mhz, 4 Core(s}, 8 Logical Processor(s) (3rd Generation) BIOS Version/Date American Megatrends Inc. E16F3IMS.30P, 9/18/2012 SMBIOS Version 2.7 There are no labels indicating which GT60 and I can find nothing that does. TIA, Scott
