END OF PROJECT
This story is about some researches and discoveries of Thunderbolt technology is ending. So that is results:
1. The connection of Apple Thunderbolt to Ethernet Dongle to Apple Wifi card from iMac:
2. Theory of how dongle caddy should look like:
3. How the rough soldering look...
I WAS READY TO CLOSE THE PROJECT AS I HAVE ALREADY DAMAGED 4x THUNDERBOLT DONGLES, TRYING TO ANALYZE DATA AND OTHER STUFF, WAS GATHERING THE REPORT ABOUT LAST FINDINGS AND DECIDED TO GATHER ALL DATA AT ONE PACK, AND... IT WAS AMAZING, WHAT I HAVE FOUND THERE!
I am not a professional engineer...
DROM MODDING:
offset 0x4C0 = CRC-8 checksum of UUID, next 8 bytes
Calculate here <=
offset 0x4C9 = CRC-32C starting from next byte (0x01), with length through one byte (0x6E) !!!!!
(Keep in mind, that Generated CheckSum Should be converted from big endian to little endian )
Calculate here <=...

I wasn't here for a long time, and sharing the materials never post before, that was used for analyze of this wonderful dongle. I am not 100% sure that everything there is correct, as it was my first study project, so...
Hi! I am not sure that this gpu support CSM. But you can try ZBOOK15_G3+G4_WX4150_HP_PEGABUILD.rom vbios version. Because mine build NEBULA, actually, for iMacs or Hackintoshes and about 8-12Kb of Legacy vbios was deleted, because at my testing gear it was working good so far, and it saves a...
