Hi to all,
The story; I wanted to build a supermicro workstation for editing, I am a student on film school.
So I bought the supermicro X9DAi motherboard, and have does evil Xeon ES CPU.
I don't have supermicro chassis.
This is a list I have on mine table everything is laying on plastic surface;
Corsair HX750 PSU
Supermicro X9DAi motherboard
2X Xeon QA90 ES chips
ATI 5770
So i connected PSU to motherboard, used one Xeon, and one stick of 4GB RAM
When I start the motherboard with short-circuit PWR pins, I hear one short beep, and after 10 seconds motherboard goes in reboot - loop. and it will do the same if there is no RAM. So motherboard is acting the same, with or without RAM, with or without the GPU.
NOTE1: I connected the LED to front header on motherboard, and LED for Overheating/Fans is steady light, meaning machine is overheating on boot up i believe, but I don't know for sure.
EDIT:
Problem was in BIOS - not able to post with Xeon ES cpu.
Downgrade your bios to version _813 and it should work.
Two ways you can accomplish this task:
1. Use normal Xeon CPU supported by supermicro X9DAi and downgrade your bios.
2. Build simple and effective LPT Rayer_SPI cable, and flash your bios chip with flashrom:

flashrom
EDIT 2:
Here is direct link from SuperMicro to X9dai_813 bios - (08.13.2012.)

I am now using FTDI based Tumpa Lite as SPI Flasher, I was not able to find SPI pins on MB so I bought SOIC8 Test Clip.
Hope this post will help some one.
