SOLVED: Shuttle DH110 not booting headless after pfSense 2.4.1 upgrade
I upgraded my Shuttle DH110 Core i3 6100T from pfSense 2.3.4 to 2.4.1 and found ever since then it will not boot headless. I had upgraded the BIOS to the latest build, then downgraded to the previous version and through process of elimination, I've found that the mini PC won't boot unless I plug in the HDMI monitor I had on hand. This was not an issue with pfSense 2.3.4.
Is this something I could submit a bug report about?
I was able to resolve the problem by disabling the two serial ports in the BIOS, per this post: https://forum.pfsense.org/index.php?topic=138057.msg755384#msg755384
Thanks. I am building a mini-router with a Shuttle DH110, and this will be helpful info. I am planning to install it under Proxmox as a Virtual Machine, which is one way of it not being headless even if the host is headless.
