    A: 1) Since it's not listed in any earlier implementatios it means that we can't recommend it as a candidate even if we wanted too.

    A: 2) Your TOLUD seems to be BFA00000 =~ 2.99GB, which it less than the limit of 3.25GB so you should be safe.

    A: 3) You can at best achieve x1 2.0 (5Gb/s) bandwidth with EXP GDC Beast / PE4L 2.1b / PE4C etc.

    A: 4) Given the fact that some EXP GDC revisions have signal integrity problems I'd go for the PE4C mPCIe solution for now, or wait for an improved "EPX GDC V9"

    A: 5) Dell DA-2 is an excellent choice of PSU for the GTX 660 SC, I just to run a GTX670 from a DA-2 myself.

    hi, I have a problem with the detection of the graphics card with a PE4C 2.1b with mPCIe adapter.

    I have a MSI GE60 dgpu 860m / egpu 9600gs. When I try to connect the 9600 is not detected, I have already tried to uninstall nvidia drivers but nothing.

    how can I fix this?

    thank you

    Why would you want to use a 9600gs when you have a 860m? For testing purposes?

    That card is very old and I think you might need setup 1.x in order to accommodate it into the PCI space.

    What system are you using?

    UPDATE:

    Alright so the "CTRL + HOME + POWER" method did not work initially, so I put the V209 bios file on my original hard drive and installed that one in system... And yeees I did go to emergency recovery! Now computer boots up again.

    What do you say, flash back to unlocked BIOS again and try to enable the "ME FW Image re-flash"?

    The reason I ask is because the G46VW/G75VW BIOS:es are easily corrupted, some people had their system bricked by just choosing "Don't save changes" in original BIOS, which makes me think that my problem could be random/unlucky.

    Hi guys.

    I found these two solder joints (resistors or diodes?) which had contact with Pin 1 and Pin 5:

    oZIBdM7.png

    There is no problem reaching them and shorting them doesn't help :(

    One note though, Pin 5 and Pin 9 seems to be connected to each other (they are both DVDD so that's logical).

    I tested just to dump the bios:

    fptwin64 -d bios.bin -bios

    No problem, yielded a 6.1MB bios.bin -file,

    I guess the ME is in the missing restricted 1.9MB.

    fptwin64 -d me.bin -me

    Gives as expected: error 26.

    ------------------------------------------------------------------------------------------------------

    Well that pretty much sums it up about the HDA_SDO method for my system.

    I'm thinking I should find my self a "ponoma soic clip", as suggested by @Arise.

    Finding an old system with LPT-port is the probably the biggest challenge.

    Could you point me to which exact components names and values I need?

    Then I'll be making an order tonight. Many thanks!

    It's definitely a valid way of unlocking the descriptor according to numerous Intel documentation. Noone said it's easy though... FPT will detect whether it's locked, it's not playing any games.

    So I should probably try some more using the same method. Could it be possible that I need to use a resistor or something between pin1 + pin5?

    Could Windows UEFI boot be any factor here? Thanks!

    Alternative #1: see if there are hidden BIOS setup settings you could change to unlock the flash descriptor. Example: http://forum.techinferno.com/dell-latitude-vostro-precision/8176-%5Bguide%5D-dell-e6530-cpu-tdp-multi-unlocking.html

    I guess that @Klem (that unlocked the BIOS) would already know about this if it was possible.

    Reply from Klem:

    "Hi!

    If ME FW is realy locked in descriptor, then it can be unlock only with hardware programmer device.

    Best Regards,

    Klem"

    (I hope you didn't mind me sharing your reply)

    @svl7

    I see that you've done a lot of work on BIOS side of the G75VW, is your flash descriptor unlocked on that system?

    Tested very carefully to short pin1 + pin5 on startup (found a joint that had direct contact with VDD pin1):

    This didn't work, I measured ~70mA between pin1+pin5 at startup, which seems quite a lot (what do I know)?

    Then in windows got the earlier mentioned behavior of sound chip disabled and ERROR 26 during "FPTw64 -d -bios.bin" (in Flash Programming Tool\windows64\).

    I don't believe this is a valid method for unlocking flash descriptor newer ASUS laptops frown.png.pagespeed.ce.k7JIVwiiFa.png

    EDIT: could it be the FPTw64 that plays me a prank, UEFI boot settings or anything else I can try?

    Good luck trying to touch pin1+5. They are so tiny.

    Instead, see if pin 5 has a track that leads to a larger pad somewhere. If it does, The can just short that pad to GND. Ideally via a small resistor to prevent shorting.

    Alternative #1: see if there are hidden BIOS setup settings you could change to unlock the flash descriptor. Example: http://forum.techinferno.com/dell-latitude-vostro-precision/8176-%5Bguide%5D-dell-e6530-cpu-tdp-multi-unlocking.html

    Alternative #2: remove the flash eeprom chip and read it with a SPI eeprom burner, flash the modified version, then solder back on the eeprom chip. You'd need a SMT hotgun to do properly. Not soldering iron type work.

    I'm going to see if those pins leads to something more accessible, I brought the notebook to work where we have a lab and equipment.

    I'll update you guys during the day, thank you so much for all suggestions so far!

    Alright guys, my audio chip is a Realtek:

    10EC = Realtek 0269 = ALC269

    My system have two audio chips, guess the latter one is for HDMI?

    Realtek High Definition Audio: 10EC 0269

    and

    High Definition Audio Device 10DE 0042 (Nvidia)

    wdsgDCk.png

    I will now do the following:

    1. shut down system

    2. find Realtek audio chip

    3. jump 1 -> 5 with paper clip

    4. pass post-screen then remove clip

    5. dump my ME

    Correct?

    To unlock the descriptor you need to use the HDA_SDO method which requires you to have physical access to the audio chip of the motherboard. So you would need to open the laptop for that.

    Oh that's no problem at all, had it fully disassembled 10 times or more.

    Is there any guide I can use to localize everything I need?

    Thanks buddy!

    EDIT: I found your example here

    Help Wrong version update of Intel ME need to update back the good one

    Now the question is which pins are corresponding to my audio chip:

    I suspect the VIA chip in the lower right of this image:
