eGPU USERS WARNING
FAN ISSUE SOLUTION:
Fan issue solution:
By replacing TMP431D DUFC with EMC1412-1 with smbus address 0x4Ch. That thermal controller is platform compatible with Zbook G3. Also added two zero resistors to pins Alert and Thermal and now thermal controller has access to mxm connector.
Note: I do own HP card
After that mod gpu temperature is read correct by Embedded Controller and fans working as native with no issues. For additional manual of hardware mod write PM. Later will make public manual.
POST error G3 only:
The catch of POST error with 4 blinks of caps lock and num lock is simple: The gpu boot with read of SPI ROM, it goes shadowed to ram address 0x34CED018 then platform (CPU or chipset) is trying to connect vbios header data to internal shadowed platform preloaded vbioses, but failing and laptop boot with failure GPU (No vbios was connected) for example to address 0x2CC18414 or 0x2DDAB410. But most of other software is working as they can work with additional vbioses stored in RAM. And next is VFCT vbioses that is preloaded from MXM SPI ROM by GOP which is also loaded from MXM at 0x37EAF068. So that will get screen working at Discrete mode. Also @theroadw found the other ACPI vbios, which is VRMB at 0x37E3901C. So theoretically HP Zbook G3 uses 5 shadowed vbioses if gpu is supported.
!!! The latest theory: vbios that is used by any OS isn`t read from SPI when OS boot, but read from PCI BAR that contain shadowed vbios. I have dumped ram with up to address 0x60000000h.
OTHER:
WARNING: Non of vbioses of post attachment was never tested under non-uefi environment or with secure boot option. Also keep in mind that vbios builds at other posts are partially or non post at discrete mode, only few of them have successfully pass testing. So use only attached vbioses to first post. 4150 vbioses are build for zbook g3, g4 and 4170 for zbook 17 g5. Possible there will be a release of final hybrid builds for iMac 2011 too. For other laptops the vbios requires connectors (objectinfo, tvoutinfo) patches.
