I picked up an ASRock AM1B-ITX to use in a headless home server, and it is giving me heartburn when I try booting it up without a display attatched. I am hoping someone can help.
It was a little quirky at first. It would hang or take a long pause before getting to the bootloader if there were devices connected to the secondary SATA ports (provided by an ASMedia chip), but I figured out that disabling "Compatibility Support Mode" in the UFEI setup screen actually solved the problem.
Once running, it was solid, and so, when I finished configuring everything, I powered it down, unplugged it from my monitor, put it in my closet and powered it up. Five long beeps, and then nothing. According to ASRock's support site, that means VGA card not detected.
After much trial and error I've determined that when a display isn't detected, it looks for an PCI Express video card. When it doesn't find one, it seems to fail back to "safe" default settings, which means reactivating compatibility support mode which, ironically, hoses compatibility with my WD Green HDDs and it stops booting.
Any suggestions here? I'm using the latest motherboard firmware, according to their upgrade utility. Linux is set up for (U)EFI boot.
Is there some sort of cheap dummy display connector I could hook to the DVI or HDMI ports that would fool it into thinking there is a monitor attached?
Any help would be appreciated.
