Download External Design Specification document for AMD A10.
Now, check what are the registers needs to be modified for enabling Virtualization, later.
Read very carefully, how the feature works, also check for AMD POR why this function was not enabled in BIOS.
If it is okay to enable, then use ReadWrite Everything utility, access these registers and modify them, restart your system.
If it works then, create a application and put in startup path, so whenever you boot to windows that application will be executed.
While I would really like to find an option in the BIOS that would allow me enable the virtualiztion, I am exploring the above list as an option. I cannot find the external design specifications for the AMD A10.
While I would still like to browse through the specs for the processor, I was able to access the BIOS using reboot, press esc, then F10 to access the BIOS. My misunderstanding was that UEFI (that's the acronym) was a complete replacement for BIOS. There is a virtualization option in the BIOS, but is not accessible through UEFI.
