Hello,
would like to see if anyone can help me unlocking this BIOS. The reason i need is is to be able to turn on/off AHCI as well as Intel Virtualization which is is currently disabled.
In addition would like to see if i can extract some more performance out of this laptop. Also if anyone can inject proc microcode to support later Socket P processors, this would be awesome...
Thanks to all

-Manufacturer: Panasonic
-Model: CF-74C/D CF74CCEAXBM
-Bios revision: 1.00L14
-Bios Type: Phoenix Technologies Ltd. BIOS (ROM) Not UEFI
-Bios Download Linkanasonic does not provide this there fore i had to use a tool to dump my BIOS into a rom file
PS: this BIOS was dumped from my current machine using a backup utility and the current backup extension is ROM not WPH...
I cannot mod a BIOS dump, because it does not contain the platform data that instructs the 'phlashing' program on how to correctly flash the BIOS. Using a hex editor, compatible platform data can be "copied" from another official BIOS image that comes from a notebook with the same chipset and notebook series. I have done this with my laptop's BIOS, but there are slight risks involved with this process, as with any BIOS mod.
You can enable VT-x without a BIOS mod though. This involves using the DOS utility called symcmos to modify the CMOS NVRAM registers. This process is much safer than a BIOS mod and can always be reverted by pulling the CMOS battery for 3-5 minutes and holding the power button for 10-20 seconds while all power sources are removed.
VT-x: Set (028E) [0000] to (028E) [0001] using notepad
DOS Commands for Reading/Writing to the CMOS NVRAM:
Code:
Reading:
symcmos -v2 -LDefault.txt
Code:
Writing:
symcmos -v2 -UModified.txt
You will need to install DOS to a bootable USB flashdrive. You can also use a CD, but a flashdrive is preferable. Instructions for the entire process can be found here.
If you have any questions, please ask.

You can confirm whether or not VT-x is enabled or disabled by using the utility at the bottom of the post. It is called "securable". If VT-x is enabled, it should show "Locked ON" near "Hardware Virtualization".
