Got my Z2 today, and figured out how to enable the Fast BIOS option in VAIO Control Center on a clean install!
You will need some files from the
original pre-install/recovery. I won't post those files since 1) my unit is a Japan-localized unit and could have possible incompatabilities, and 2) Sony might get upset. But I'll explain below where the files are.
These instructions assume you are installing a 64-bit version of Win 7.
PRE-REQUISITE WARNING: This worked for me, but there could be some other setting on your unit that causes a conflict. Make sure you back up!
First, we need to get the necessary files.
- Restore your system to the original pre-install using the restore partition, DVD, or USB drive. Remember, doing this will wipe the whole drive, including any additional partitions you may have created. Make sure you backup!
- The files we need are in: C:\Program Files (x86)\Sony\VAIO Boot Manager\*. Just copy the whole directory and keep it in a safe location, such as a USB key or another computer.
Next, format and install a clean copy of Windows 7 as you normally would, and install all the standard Sony utilities (Shared Library, Notebook Utilities, etc). Or restore a system image.
Finally, let's add the Fast BIOS option back:
- Drop the files from VAIO Boot Manager back into their original location on the new system (C:\Program Files (x86)\Sony\VAIO Boot Manager\*).
- Last, we need to let Control Center know to load the files. Add this registry key:
Code:
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Sony Corporation\VAIO Control Center\Plugins]
"VBFSetting"="C:\\Program Files (x86)\\Sony\\VAIO Boot Manager\\VBFSetting.dll"
If in doubt, you should see a string value inside the Plugins key with name VBFSetting and data C:\Program Files (x86)\Sony\VAIO Boot Manager\VBFSetting.dll.
- Reboot, then open up VAIO Control Center. You should see Fast BIOS.
Sorry for not posting the files. If you didn't create recovery media or can't be bothered to restore, maybe someone else might be willing to post their files.
Frankly, the Z2 is already speedy. I'd say Fast BIOS might shave 1 or 2 seconds off the boot time, but it could just be a placebo.
