Hi

I'm trying to unclock the FD on latitude 6430u but I could not find the audio chip for the pinmod so now I'm trying the setup_var method but unfortunately my bios seems to be compressed on UEFITool N58 :



So I cant find the varoffset of the param "Me FW", any clue on how I can decompress the content so that I can feed it to ifdtool ?

Thank you

Out of curiosity I tried a bios from a more recent latitude laptop and it's not compressed as you can see on this screenshot and I'm able to use exported sct file with ifrextract (not ifdtool):



./ifrextract Section_PE32_image_IccOverClocking_IccOverClocking-test.sct 6430u-test
Input: Section_PE32_image_IccOverClocking_IccOverClocking-test.sct
Output: 6430u-test
Protocol: UNKNOWN
error: Unknown protocol

I feel I am missing something obvious

thanks I found the setup part but how do I use it with the ifrextract tool ? or should I use another tool ?

Input: Section_PE32_image_Setup_SetupPrep.sct
Output: fsfdfs
Protocol: UNKNOWN
error: Unknown protocol

Hi :O)

Works with IFRextract, no problem :

Yes latest version but I juste find why it was not working ... I knew it was something stupid lol
I was doing export from the PE/32 part not the hole SetupPrep part which is why it was not recognized I guess by IFR-Extractor


EDIT:
Ok so I found the param "Me FW ..." set it to 1 rebooted and was able to dump full image with fpt which I could not before this.
Problem I cant flash back the FD with fpt, it says the CPU does not have access .... same message I had when the FD was locked a bit weird
I can try to flash the hole image but I'm a bit scared dont want to brick it :/
