Yes, please.

But do not dump NVRAM with DarwinDumper, but dump "Firmware Memory Map". Please also attach the ROMs used.

 

Dumps from two version of BIOS - 0217 preserve NVRAM, 0412 have broken NVRAM.

 

If you need any more dumps, tell me what you want, I'll do it.

I can flash bios without any risk. I have Usb Flash Back on board, and a hardware SPI programmer. I have a copy of the contents of the flash.

On some Z97 ASUS motherboards, for example Z97-C write to NVRAM worked with BIOS to versions 2403. Later version not preserve NVRAM. 
 
Does that help, if I asked some from my friends who have this motherboard for making dumps from version which preserve and don't preserve NVRAM?

No need for dumps if you cannot boot OS X. :P
This is the last idea I have without actually reversing the code: https://www.dropbox....ix2Drv.efi?dl=0
This should actually boot again... idk if it will work.

 

In this buld I can boot to Yosemite, but nvram not works. Previus buids macOS not working at all - hangup or reboot on boot. 

 

A slightly little bit vague...

 

forget - my mistake...

 

here is dumps from my motherboard: ASUS Maximus VII Impact (Z97 + i7-4790K) BIOS 3003, dumps from clover 3922
