I have assembled PC based on Intel D2700DC mini-ITX motherboard to use it as headless server. I was able to install Fedora 17 Linux on it, and it worked fine until I disconnected display.
It still works perfectly if display disconnected after it booted, but won't start unless display is connected.
I have updated BIOS to the latest revision, turned EFI boot on and off, juggled video settings but that had no effect.
Initially, I thought it was a GRUB2 loader problem, so I used /etc/default/grub from this thread and regenerated grub config, but that had no effect. It also behaves same (boots with display, doesn't without it) with live usb stick with MS-DOS I have used to update BIOS.
Is there any way to make it boot without display connected?
