Hello,

I have an Elitedesk 800 G1, and i tried install an I7 4790 ES (Enginering Sample), when i boot the machine, appear a error saying that my processor don't have a microcode correct (microcode update error 1801) 

Learning some about microcode, i think i need add the microcode for this processor family on my bios, correct?

Post a screenshot of third (Mainboard) tab of CPU-Z with supported CPU.

I tried do a dump of the bios, but i think the CH341 can't read this chip (Micron 25Q128A 13EC0, 128MBit SPI Flash, SOIC-8)
OK. Now do:
fptw64 -a 0xE90048 -l 0xD8 -d fit.bin
Give me fit.bin
