How to Enable Intel VT and AHCI on a Napa/Santa Rosa platform Phoenix BIOS Vaio laptop

[zii]

For Napa SZs - R0112N0

AHCI: (015C) [0000] ---> (015C) [0001]

VT-x: (0354) [0000] ---> (0354) [0001]

Therefore these tokens won't work for my BIOS. I looked at the first page and it does not (unless inferred) explain how I ought to locate the correct token. I am certain that there are many tokens set to 0000 in the BIOS and changing one of these might well result in the open laptop and unplug battery procedure.

Is there some method to locate the tokens?

Other than reply #9, you can try to enable VT-x using Phoenix BIOS Editor and write the modified BIOS to your notebook, which someone in this thread had successfully attempted. If all goes well, finding the tokens aren't necessary since VT-x is already enabled, but if you'd wanted to find them anyway, you could create a table from that modified BIOS using symcmos and do a file diff with that and a table from an unmodified BIOS to see what tokens have changed. That should be quicker than finding it by trial and error.

Is there an official Phoenix site I could d/l the Phoenix BIOS Editor from? I did not see any links to this in my search in this thread.

I believe information about where to download PBE is located somewhere in this thread. Did you read the whole thread yet?

I remember trying to use similar versions a year ago and these failed because my machine name was unrecognised. I will try again.

Would you mind providing a screenshot of the failure while updating to R0112N0 so I could revise my first post if what you are saying is indeed true? As it says in the first post, make sure you have all the proper Sony drivers and utilities installed in XP before attempting to update. Information about how to do a clean XP install on an SZ can be found here.

I will let you know when I install the new bios version.

"make sure you have all the proper Sony drivers and utilities installed in XP before attempting to update."
I doubt I do. I only use WinXP for one computer game and this is seldom.

Is there a way of doing this from Linux (debian in my case)?

Ahh. Found a few links. https://launchpad.net/vt-enable
Does not look like it has been finished yet, but I shall contact the author.
