The Marcan Method to enable vt-x on an Acer Aspire 8930g laptop (other makes and models probably can use this technique to unlock the hidden menus in an Insyde H2O UEFI BIOS.
Hector Marcan says:
The easiest way to enable the setting as far as I can see is to dump out the entire BIOS, patch the setting into the Setup variable (which is part of the data storage section - we aren't modifying any actual BIOS code, as this is the equivalent of changing a CMOS setting on other BIOSes), and then flash the resulting image. These laptops use a weird flash-behind-EC hardware solution for which there is no open flasher, so instead we can just use the normal BIOS flashing tool. In short, we'll flash the existing BIOS back on, but in the process also modify a Setup setting.
The list of programs below are those suggested for use by Hector Marcan in his blog - Abort, Retry, Hack?
