(UEFI) Dell XPS 15z L511z modded BIOS - and HOWTO

@kasar - try this:

1) Dump your Desc table via fptw.exe -DESC -D DESC.BIN
2) Open FITC and load up DESC.BIN
3) Go to Master Access Section, and select Manageability Engine.
4) Change Read/Write Access to Enable
5) Go to CPU section & change bitmap as per post on rag.asus
6) Save DESC_MODIFIED.BIN (in compact mode to get it to 4kb)
7) fptw.exe -DESC -F DESC_MODIFIED.BIN

I see... that's what I assumed at first, SMBIOS firmware capabilities define what's shown and whats not.
But looking at 17R SE has kind of lead me into thinking the opposite ..

His main thread is over at overclockers.ru (hence the reason I do my "rough translations" of the said quotes), but he's also somewhat active on hardforum.com
I've asked about FITC as well, he said that virtually nothing can be unlocked with this tool .. even on desktop boards it doesn't do any justice ..

Sure you can try, but I will be highly surprised if it works. At least I wasn't able to unlock anything using this tool. There surely is some other algo used to control these features.

Well, won't disturb you any longer .. enjoy the wedding

thanks mate

good luck kasar as well - will get back to some more helpful advice once i'm back from the wedding (and reduced alcohol consumption )

I'm also looking for:
"Phoenix Technologies SecureCore Tiano Technical Reference Manual -Vol 2"
So far I've stumbled upon only the first chapter of it: http://notebook.tmx.hu/bulletinek/Phonix_Bios.pdf
Why you may ask?
There's this person supposedly taking some training to become a Phoenix agent.. (http://www.phoenix.com/pages/training) he makes notes to himself on some wordpress blog: http://kunyichen.wordpress.com/
And even though the snippets are somewhat useless we can at least see that there's an SDK somewhere in the wild available to certain people as well as some sort of documentation to accompany it.

ok, trying those atm

fptw.exe -DESC -D DESC_BACKUP.ROM
fptw.exe -ME -D ME_BACKUP.ROM

here are the backups

at the step 3)

wasnt that what I made by desoldering , flashing from lpt directly to chip, and resoltering back to the mobo in order to unlock that stuff?



also didnt got step 4, what bitmap option I have to change?

[jkbuha]

Sorry kasar difficult to type everything when u have a few drinks too many

I meant the following (copying and paste from my previous post a few weeks back)

1) Dump ME using fptw.exe -ME -D ME.BIN. If correctly unlocked you should be able to dump this file.
2) Load up FITC and load ME.BIN
3) Under ME Region goto Configuration/ICC Data/ICC Profile 0/FCIM/BTM specific ICC registers
4) If Clock Source Select is 0x00011A33, then the Dells use the PLL built into the PCH, so we can change it to 0x00011A34 to enable overclocking. If this value is something else then we cannot enable overclocking like this
5) If successful save ME_MODIFIED.BIN in compact form
6) fptw.exe -ME -F ME_MODIFIED.BIN

Good luck!

Where do I get Flash Image Tool: 7.1.20.1119 again ?
By the looks of it you are loading up an entire backup of the flash ?
edit: nvm .. got it
