BIOS R2022M4

What is this?
BIOS stands for Basic Input/Output System.
It refers to a piece of firmware which is run when powered on. Its primary functions are to identify and initiate component hardware, and to prepare the computer so that other programs can load.

What does it fix?
It may take a while for the VAIO logo to appear when TPM and Bitlocker are active.
Compatibility issue with Bitlocker.

If your VAIO hardware supports Intel Virtualization Technology, this setting will be added to the BIOS. The VT setting is disabled by default.

Important note:
Even if this BIOS is posted for your VAIO model, it will only create the BIOS option for models with a VT-compatible CPU.

To test if the CPU of your VAIO is compatible with Intel® Virtualization Technology, you can also download and install the Intel® Processor Identification Utility, which can be found here:
