Microsoft sent me an updated ASUS bios (1902) to solve my problem of hardware virtualization not being enabled after resuming from sleep mode. This was an unexpected pleasant surprise after receiving this email from ASUS yesterday:
Dear Valued Customer,
Due to the win7 is not supported by the motherboard, so we suggest you to use the win vista or winxp.
Our QT have test that the virtualization work ok under win vista.
If you problem is still existed you could contact to our RMA center for a repair or replacement.
Sorry for the inconvenience.
This latest bios appears to have fixed my other problem of sometimes but not always having to reinstall my network driver after a reboot. I can’t really credit ASUS with resolving my bios problem. It was really Microsoft I have to thank.
Gigabyte’s latest bios seems to solve most people’s problems in getting hardware virtualization enabled. Sony VAIO owners still must resort to this hack or the symcmos hack to get hardware virtualization enabled.
