is your drive in the WiFi slot or on the WWAN slot ?

WWAN slot. This is shown on the schematic.

@adrian_sa, we are still waiting for your explanation about the mod how to change the screen. Where did you solder the high-speed pairs on the motherboard? And show schematic of every wires that you soldered on the motherboard. How did you do VBT modding? How did you change the default LVDS resolution to 1080p and the BL PWM frequency to 2000Hz?  Everything pls.

@invait53 Sorry, I was busy using the notebook in the field :D So far the mod holds up. I soldered the pairs to the dock connectors, there are vias on the board from which you can scrape off the solder mask and solder the pairs. Also you need HPD and I soldered the backlight enable and PWM pins to the pins of the old LVDS display. To do the VBT mods download the UEFITool and search for $VBT in non-unicode, you will find three modules, extract their bodies and open the files with Intel BMP, you can find the tool in the winraid forum. Now its been a while and I dont remember all the changes I did, I will have to find the bin file and share it here so you can compare. My method is flawed because right now I cant use a third monitor, the old LVDS interface is still working because of the backlight part, I will have to disable the LVDS and add a Arduino to control the backlight instead. I think that the HPD pin goes low when the display goes to sleep so I could probably use that.

If you have 16Gb RAM, I recommend you to download the very old and known software "PrimoCache"

Thanks for advise but my SSD is Samsung and I use the program Samsung Magician with Rapid mode. I think it's the same functions.

 

@adrian_sa, did you use for your mod capacities like in DisplayPort connector:

Hi, guys, please forgive my english is every poor, I hope you can understand what I said. about msata, I delete the BIOS's SecureUpdating module and modified PlatformSetup module, removed the modem option, added the msata option, msata works perfectly, but can't boot the system directly from msata. The BIOS version I use is F.72, modified with the UEFITool tool, if you are interested, you can test it, but you must be careful, you must know how to use UEFITool and flash BIOS. It is important to backup your original BIOS before you start.

The motherboard's WWAN socket sata line needs to solder four 0.1UF capacitors or 0 ohm resistors.
I also changed the TFT to 2K display, using the DP in the docking station's interface.

Just done messing up with bios write protection.
 


PchBiosWriteProtect
BIOS lock
00 B2 FE 48 81 C1 DC => 00 B2 FF 48 81 C1 DC
SMI lock
00 B2 20 48 81 C1 DC => 00 B2 00 48 81 C1 DC
PchSpiRuntime
00 00 B2 FE B9 DC 80 => 00 00 B2 FF B9 DC 80

Checked on ther F.73 bios version.
Unfortunately, in F.73 bios FDO hotkey is banned - nb just turns off right after start, so additional flash descriptor region edit is needed.
Here is patched bios section binary for your needs. It contains: no WWAN/WLAN/Bluetooth whitelist, no SecureUpdating module, no CompuTrace modules, BIOS lock removed, no_ASPM_bit in FACP is reset. No NVRAM.

How to flash:

  1. Get a full dump of your stock bios, make a backup
  2. Extract the NVRAM section from it with UEFITool (BIOS Region => FFF12B8D-7696..., Extract as is)
  3. In hex editor open the full dump and replace bios section, start address 0xB00000 ($LOGO string)
  4. Replace the NVRAM section with yours in UEFITool (Replace as is)
  5. Edit FDT at address 0x60

00 00 0B 0A 00 00 0D 0C 18 01 08 08 => 00 00 FF FF 00 00 FF FF 18 01 FF FF

And flash it with hardware programmer.

 

Possible issues: don't know why WIn8.1 boots too long, because of edited bios, shrinked MEI or just because it can.

 

As for mSATA, i'm not succeed at this time, maybe later. If someone want to try search where is satacontroller is initialized, here is the list with modules that different between 2570p and 8770w (don't checked bios versions though).

2570-8770 module diff list.zip

If am I right, according to hp 2560p schematic, if we remove the wwan whitelist we can get egpu pcie x2 2.0 bandwidth with expresscard and wwan mpcie slots.

Hello, how do you found that? Did you edited IFR section (or replaced from 8*70 PS module)? I see a lot of changes. Am i right that WWAN-device will be inaccessible then? I've noticed that Bluetooth option after removing according module didn't affect anything thought, maybe with WWAN will be same story.

but can't boot the system directly from msata.

Well, there's no surprise. @juandante asked about msata-enabled RAID, maybe it's available now.

Good work anyway.

Only if pcie lanes is physically wired to the slot. @adrian_sa tested WLAN card already in the WWAN slot with no success. I've checked some schematics, pcie is wires into the same pcie pins that mSATA is used, so there signal commutator is needed. Dunno if it really exist on the motherboard side under the keyboard, but i think there is just no any option for combo cards in WWAN slot.

Our chipset is Mobile Intel QM77 Express. That chipset has 4 ports of SATA2 and 2 ports of SATA3. SATA HDD and SATA ODD are SATA3. It means that in our laptop available RAID0 only.

 

Two people here have done the display mod but nobody wants to share it.

eDP and DP are compatible, you can buy the cable I linked a few pages ago and solder it directly to the board, The vias are exposed near the dock connector under the heatsink.

@adrian_sa Thank you very much. If I'm not mistaken, with your mod I'll not able to see Bios. Did you twisted the line wires? What the length of cable? In theory this mod let me use the 4 line display. @bg6dt have done the mode with 2K screen. Maybe by the same way. I hope he will share it with us.

I used the wire that I linked on aliexpress, just cut off the connector and solder the wires directly. I can see the BIOS, posted also about that, the BIOS doesn't work in full UEFI boot mode but if you switch to hybrid it does work. I also modded the VBT so I can use clone mode for the display. Right now I can you only the internal display or an external display via DP or VGA. I can't use extend mode. I dont know if 4 lines would work with this basic method, 1080p uses RDR(reduced data rate), for 2k you need HBR so there is bigger concerns about signal integrity.

 

The next step would be to implement MCU which would take care of the backlight control, but I don't where to get the Backlight enable pin if I disable the LVDS interface. The HPD pin is always high when machine is on. The Chinese x230 FHD mod uses USB with software I suppose to control the backlight.

Yes, what you said is correct. I compared the BIOS of 8770W. after edited the IFR section, the key point is this: Variable: 0x368, and I have deleted the WWAN module using UEFITool. I plugged the bluetooth device into the WWAN socket, bluetooth Work perfectly, no whitelisting problem.

Backlight enable detection, I used the voltage detection of Lane0_P, when the EDP has a signal, the voltage is 0.5V, when the EDP has no signal, the voltage is 0V, MCU uses ADC detection, output high and low level signal control panel backlight.

 

Backlight brightness PWM, MCU detects keyboard FN+F9 and FN+F10 buttons, output PWM signal  control panel brightness .

 

Modify BIOS VBT, modify with Intel BMP Utility tool, delete internal LVDS display, do not use clone mode, only one monitor, full UEFI mode works perfectly, external monitor works perfectly. The BIOS version I use is F.72, see VBT.ZIP file. 

 

2K panel model: LQ125T1JX03C

 

Edp signal cable, I made it myself, the signal cable length is 13cm, the differential signal cable is twisted and twisted, covered with shielding tape.

@bg6dt Well done. Can you do that plates more and sell it? Very interesting mod.

 

I've found on Ebay LVDS to eDP converter. Very simple to install.

Would be pretty interesting to have a 2k screen, because with the 2570p + 3820qm and the low-res 768p screen I often feel like the power is not fully used.

I am not a businessman, doing this is just my interest, so I am not ready to sell these.

 

The 2570p has only a single LVDS signal, and the resolution cannot be used above 1440x900. If 1440x900 or more is required, a dual LVDS signal is required.

That's great. I am very happy that this is helpful to you. You mean IntelIvbGop and IntelS nbGop drivers?I replaced the new driver with the UBU tool(UBU_v1.71.1).

 

I am curious to know how your backlight works, panel enable signal and the pwm signal.

@bg6dt Thank you for PCB layout file. Last things what I want to ask you. Write here detailed instruction how did you apply the VBT mod and replaced the new driver with the UBU tool. Wrire every step because mostly people don't know how to use  Intel BMP Utility or UBU tool.

      Hi there guys,
       
      I've been looking into getting a new GPU for my laptop (4-lane PCI-e) and enclosure (HP Omen Enclosure) but I cannot decided between the RX 5700 XT and the RTX 2070 (non SUPER).
       
      I did some price to performance calculations (higher is better) with some of the best prices I can currently get in the UK.
       

       
      The RX 5700 XT does perform better and is cheaper than the RTX 2070 (Although the 2070 does come with 2 games) but my main concern is drivers and from what I've heard NVIDIA cards work a lot better with eGPUs than AMD.
       
      If anyone has experience using both red & green or if anyone else has any other input i'd love to hear your experiences and input.
       
      Thanks.

      Hi guys, bit of a rookie to the whole EGPU scene. Currently I have:
       
      - MacBook Pro 2015 13inch (3.1GHz Core i7 16GB RAM)
      - Razer X Core 
      - Apple TB3 to TB2 Adapter
      -  TB2 Cable (Cable Matters)
      - 23inch AOC External Monitor
       
      I am wonder about what graphics card to get to run X-Plane11 with high graphic settings?
      I have purgewrangler set up and ready to use with an AMD graphics card, but am also open to the idea of an Nvidia graphics card.
      Any advice appreciated. I did not buy a Windows PC as I need a Mac for various other things and wanted an all-in-one laptop.

      To anyone wondering about eGPUs on M6700s, its not too complicated, there is just a process that must be done on boot every time:
      You need to have the eGPU connected and powered on before booting the laptop, once you get to the Intel RAID screen disconnect the eGPU and wait for windows to load up, once windows is loaded reconnect the eGPU and you *should* be able to use it and be able to hot-swap it (though you should disable it in windows before unplugging it) installing the normal AMD drivers worked fine for me, though the original release of Adrenaline 19.1 blue screened the first time.
      I usually run with 3 1080p monitors attached to the 480, replaced my old i5 desktop with this laptop due to the convenience of storing everything on one machine, the laptop has a 256gb SSD and 2x 750GB hdds in raid 0, there is a 2TB WD black attached to the eSATA on the dock.
      eGPU and external HDD are powered by a 500W evga desktop ATX psu, the EXP GDC's ATX power adapter was clunky and broke while trying to use it, so I just plugged in a CPU 4 pin cable upside down to power it, not worried about it because the bulk of power is coming from the 8 pin on the GPU anyway.

      The GPU works, The PSU works, The system works. [individually they all do work]
       
      The system works perfectly fine without the WLAN card.
       
      When i put the system to sleep and hotswap the mPCIe riser and WLAN press something on the keyboard.. Restarts.
      Will shutdown in roughly 27 seconds for those 27 seconds it works just fine like how it normally would on external monitor.
       
      When i shut it down and plug the riser and switch it on, same story. 27 seconds.
       
      I don't even see a error. I get to login screen directly. I used DDU already.
       
      I timed it. no matter what i do if i use the eGPU, External monitor it restarts instead of pause-play. I have 27 seconds.
       
      Need help!

      I got the exp gdc beast 8.5 got all the connections right... laptop boots up... fans turn on the gpu.... device manager detects gtx 1060 with a “ ! “ in a yellow triangle. Now what to do.... i tried to do the bios mod.... but realised that i have 3.07 version. 
      Questions-
      1 is there any way to get this done without the mod?? 
      2 if mod is the only way... kindly help me with step by step instruction in laymans terms... i m not a techy... so i might not understand technical terms.... altho i am interested... but learning yet. Please help.
