Where is COM port #1?
The first COM port is marked on this photo:
DH310 does not show a picture with installed Intel 9xxx CPU (Coffee Lake Refresh)
In case your DH310 does not boot with installed Intel 9xxx CPU, please follow the procedure below.
The system is running with 9xxx CPU, but due to different graphics unit, the BIOS needs to be updated to get an actual screen output. The following procedure will explain how to “blind flash” the system without an initial monitor signal.
You DO NOT NEED to install another “older” CPU for the update!
