Hi guys, I did not find an "Introduction" Sub Forum so I didn't introduce myself, apologize for that and I'll sure do it if I found out where or you link me to it!
I need some guidance/ help with the Ami Bios from some Sony Vaio Pro 13, here is some background...
I own some of these laptops which I got pre-owned at Ebay or similar over the last years and a few weeks ago after buying the 4th, I found out the Product Version, S/N, Tag and UUID were missing (marked RESERVED on Bios). I went to check the others and to my surprise only one is correct, another doesn't match Chassis and the third also as RESERVED.
Maybe the Boards were replaced, bad bios flash, I don't know...
After long reading here and there I've tried editing this info with various tools and versions of these, Dmiedit, Amidedos, Amibpc, and Hex using UEFITool v28. I've also searched for some Sony version of these tools but never found info about such tool.
The Sony Vaio Recovery Mode screen ist also tied to the System Information Type 1 as it shows the Product Version, S/N and Tag number as soon you boot into bios.
What I've tried and/ or achived so far:
I made Backups from all roms and tried looking into all of them on HxD but on the Decoded Text columm I can not decipher anything... I don't have the knowledge for that...
I was able to insert Product Version, S/N and Tag in one clean rom extracted from Sony .exe only because I could find the word RESERVED in it, but no clue where to the UUID goes...
-Dmiedit within Windows doesn't work because this Bios have write protection.
-Amidedos from DOS doesn't work and command "Amidedos /all" shows all Info as Read Only ®
-Amibcp within Windows does work but Info on System Information Type 1 does not show up in Bios although Amibcp saves it without error output.
-UEFITool+ HxD got the job done for Product Version, S/N and Tag but I can not find out where to insert the UUID...
I've save some txt files using Amidedos and there are also some lines under OEM String #1, #2 and #3 showing two long strings on two laptops but not on the one with my test rom.
I would like to know where the UUID goes and what these OEM Strings are so maybe I can understand a bit more of this.
If someone can show me how to make sense of all the characters under Decoded Text in HxD, maybe I'll be able to further edit myself.
All Bios are language are EN but the Vaio Recovery are in defferent language as follows:
- clean/ test roms Recovery is EN
- BACKi7.rom Recovery is Chinese or Japanese
- BACKi3.rom Recovery is German
I'll be thankful if someone does it for me but I really would like to learn it and will be more than happy if someone can guide me through.
You find all the roms with the txt and some HxD screenshots with the S/N offset below and please let me know if you need more from me.
And sorry for the very long writeup... maybe too much unnecessary info but I thought it might help something.
Thank you in advance and greetings from Switzerland
EDIT:
Somehow I can't see the my zip file on the post neither on my uploaded files so here is my Mega link.
