Intel® Server Board S1200KP Startup problem

[idata]

Hi to All,

I recently build a mini-ITX Server based on Intel® Server Board S1200KP coupled with,

Intel Core i3 2100T

160GB 320 Series SSD

Silverstone ST45SF SFX Power supply (450Watt)

Kingston 2*4GB DDR3-1333MHz Non-ECC Ram KINGSTON KVR1333D3N9/4G Modules.

My Problem is that the board is stucking at Logo Screen with bios initialization code of EB.

I don't know where the problem lies to?

Can you be of some assistance?

POST code EB means "Calling Legacy Option ROMs". Do you have any add-in card attached? Remove all devices and leave only PSU, CPU and memory, and boot the system. If you hit during POST, can you go to the BIOS setup screen?

I do not have any add-in card attached. I am not able to press F2 to enter bios either... i am stuck to logo screen.

As i said before the only device i have attached is the ssd, exept cpu memory and psu...

My problem lied on a USB DVD-RW that needed 2 USB ports for operating ok. Since i plaggued it in my motherboard got frozen....and when removing it, all was fine again.

I had to install my operating System (SBS 2011 Essentials) using a USB flash drive for booting.

All is well know.
