(UEFI) Dell XPS 15z L511z modded BIOS - and HOWTO
@jkbuha
We are still missing:
Code:
* Express Charge
Express Charge  = a Dell fast charging technology
Standard Charge = batteries charged over a longer period of time
Note:  ExpressCharge may not be available for all batteries

* Wireless Configuration
    * Wireless (Switch)/(Hotkey)
    This setting determines which wireless devices will be controlled by the wireless
        - None = The wireless switch is ignored
        - WLAN = The wireless switch only controls the WLAN device
        - BT = The wireless switch only controls the Bluetooth device
        - WLAN & BT = The wireless switch controls the Bluetooth and WLAN devices
        - WWAN = The wireless switch only controls the WWAN devices
        - WWAN & WLAN  = The wireless switch controls the WWAN and WLAN devices
        - WWAN & BT = The wireless switch controls the WWAN and Bluetooth devices
        - All= The wireless switch controls all wireless devices
        The factory default setting is All
    
    * Internal Bluetooth
    This option lets you enable or disable the internal Bluetooth device
        - Disabled  = The internal Bluetooth device is off and is not visibleto the operating system
        - Enabled   = The internal Bluetooth device is enabled
        The factory default setting is Enabled

    * Internal WLAN
    This option lets you enable or disable the internal WLAN device
        - Disabled = The internal Wi-Fi device is off and is not visibleto the operating system
        - Enabled = The internal Wi-Fi device is enabled
        The factory default setting is Enabled
        
    * Internal WWANThis option lets you enable or disable the internal WWAN device
    - Disabled = The internal Wi-Fi device is off and is not visibleto the operating system
    - Enabled      = The internal Wi-Fi device is enabled
    The factory default setting is Enabled
    
* Boot Configuration:
        * Boot Priority
        Select proirity of boot option between UEFI and Legacy
            - UEFI First
            - Legacy First
                
* ME Configuration

        * Intel AMT
        Enable/Disable Intel (R) Active Management Technology BIOS Extension
        Note : iAMT H/W is always enabled
        This option just controls the BIOS extension execution
        If enabled this requires additional firmware in the SPI device
        
        * Intel AMT Hot Key
        Enable/Disable Intel AMT Hot-Key during POST to enter MEBX setup
        
        * Intel AMT Setup Prompt
        Enable/Disable Intel AMT Setup Prompt to wait for hot-key to enter setup
        
        * Intel AMT SPI Protected
        Enable/Disable Intel AMT SPI write protect
        

* OverClocking Feature:
    
    * Performance Menu for Processor and Memory
        
        *Processor Bus Ratio Override and Bus Speed Override
            *CPU Flex Ratio Settings:
            This value must be between Max Efficiency Ratio (LFM) and Maximum non-turbo ratio set by Hardware (HFM)  
            
            *Flex Vid Override:
            Vid Override Paramters. Value varies from 8-48 (08h-30h),which relates to volts 14000v to 09000v. Each step equates to 00125v
            
            Bus Speed Support:
            Enable/Disable CPU Speed Override Support  
            
            Bus Speed Override:
            Value entered will be taken as overclocking percentage (%)of current clock frequency. Value varies from 0%-49%(0h%-31h%)

            - Enabled:clocks for empty PCI/PCIe slots will be turned off to save power Platform must be powered off for changes to take effect
                
        * Lock ICC registers
            All registers: all ICC registers will be locked
            Static only - only static ICC registers will be locked
I've looked at 17R SE BIOS (SCT 2.1) and it appears that hidden menus are suppressed by questions in there.
Maybe it's the case with our missing options as well, or are you dead positive there are no *links* between menus and unicode strings in the module?

Also got heads up from @CodeRush:

Quote:1. ME v8 is required for Ivy Bridge support, without it there's no way 22nm CPU will work on 67-chipset
2. Regions are usually the same size on all platforms, the entry (start) points differ for different flashing software though. In UEFI BIOSes ME starts right after the Flash Descriptor (so 0x1000h in our case)
3. After FD lock has been set by OEM there's no software way to remove it, even the OEM flasher won't eliminate the lock. The only way to get rid of it is to flash 12 bytes 00 00 FF FF 00 00 FF FF 18 01 FF FF at 0x60h, that is correct for all the platforms.
4. If you try to flash the .cap from OEM onto the chip all the info in NVRAM storage will be wiped, so all the motherboard propriatory details will be lost foerever. Having an entire hw-based chip backup is a must!
5. The header 0x1000h - 0x37FFFh is common for both v7 and v8 ME firmware. If there's is old UEFI on the board it is unable to utilize 22nm CPUs and even ME v8 won't help here, because UEFI 2.0 has no support for it. If Dell does not release a single BIOS with ME v8 for your particular machine - there no way to have ME v8 and 22nm CPU support. Even if you had SDK/sources at hand we would still be helpless here, because as far as i know even ASUS had to ask Intell for support in regards to implementing the ME v8 into their BIOS. And still they failed miserably at it.
To conclude: Ivy Bridge and v8 ME support without the manufacturer's support is a dead end.

@TimeWalker - all the menus have been unlocked. What remaining options will be shown depends on the status of the hardware registers, which in our 15 series case means either WWAN/BT/Cell hardware toggles (which we don't have) or the ME configuration. For instance when I reboot from BIOS recovery mode I get the iRST menus as well, which I dont get in normal boot.

Re: ME v8 - I don't think we should play around with v8 for now. I think we should try to unlock v7 with the FITC tool (just like I proposed before) to see if the Clock + Voltage menus show up in the CPU sub-menu. That is something we should easily be able do now that the descriptor region is unlocked.

CodeRush sounds like he knows a thing or two about our BIOSes - which forum(s) is he on, and can he pop over here as well to help us? Smile
EDIT - no worries I've found his posts.

@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 ..
Quote: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 Smile

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? Big Grin

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

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

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! Smile
