I am creating this thread for all all of those who want a SAFE way to enable VT-x, AHCI, or various other options that do not show up in their Phoenix BIOSs. This method does NOT involve flashing the BIOS. Only the CMOS NVRAM is modified, so any changes made can always be reverted if necessary and will never result in the corruption of the BIOS. Please note that this is NOT a BIOS modding request thread. This is only for NVRAM Registers.
![Big Grin]( "Big Grin")
NOTE: I am building upon a "master list" of NVRAM registers created by ScuderiaConchiglia (Gary) from notebookreview.com. All credit for the original creation of the list and >95% of the VT registers goes to him. He gathered users' submissions of working NVRAM registers for each notebook/BIOS and organized them into one list. My contributions include the AHCI registers, posting of the list here, and <5% of the VT registers.
The way that I find NVRAM registers involves the BIOS image itself. The image is decompresed using AndyP's PhoenixTool and then the TEMPLAT0.ROM and STRINGS0.ROM modules are inspected to identify the registers. This method works very well on new-style phoenix BIOS's.
So far, there are only Sony notebook models on the list as it came from a thread about Sony Vaio models. I am going to divide this list into different sections for each manufacturer.
As for register compatibility, the BIOS version must be the same. The notebook model is irrelevant. All that matters is that you have the
same BIOS version.
If you wish to contribute to this list, there are 2 ways of doing so:
1.) Upload/link your BIOS file (dump or official update) here so that I can download it and figure out the registers for VT-x and/or AHCI.
2.) Figure out the register on your own. There are 2 primary ways of doing this. The first involves trial-and-error with symcmos. The second way involves inspecting your own BIOS image. Please double check your work if you use this method.
I will be posting user-friendly tutorials on how to perform both methods of "register hunting."
If you have any questions, confusions, or needs for clarification, please post a reply on this thread or PM me.
My ability to add registers to this list depends entirely on user submissions of their BIOS images or their own findings.
Currently, I am only able to identify registers of new-style phoenix BIOS's, but I will be looking into others in the near future.
