I finished to install my new micro computer based on the asrock Q1900TM-ITX motherboard. The problem is that computer is intended to work with no other cable connected than the power supply and the network cable. If I do this, the computer does not start up.

Is there any configuration that I should set on the BIOS?, is this a BIOS issue?, I want this computer not to halt on any error (no keyboard, no mouse, no screen...), as I will access to It remotely.

Please, advice.

Welcome to the forums Smile

You could try going into the bios under "Chipset Configuration" and set "Share Memory" to anything other than Auto. That should force the system to recognize the igpu even without a monitor attached. 

Let us know if this works for you Wink

I'm 100% sure that the current value is Auto. I was looking in the BIOS this morning trying to look for a function like "halt on error" but I found nothing.

I have no access to this box, this evening (GMT+1) I will try to set this parameter to a fixed value and try.

Question: which value should I put for LVSD?, currently It is disabled, is this the right approach if I have no screen at all?

Setting the shared memory size to a fixed value didn't help, however, activating the lvds in the BIOS did It

Is this a bug or a feature?

Investigating a little bit I got that this is not the only Bay Trail-d with this issue:

This board cannot boot without a monitor connected to it. (Tested with BIOS F1 and F2). 
You can make a VGA dummy plug to run the board without a monitor. Google "VGA dummy plug"

We need a fix for this, because most of these system are perfectly ideal for building micro servers, as their consumption is minimal, non existing heat and no noise

AsRock, please, help us.
