I've got a strange problem on my successfull insalled OMS on a QNAP Nas TS 269 pro. I installed latest stable, OMS 4.1.30 on micro SD card connected on USB 3.0 port. I installed the flashmemory plugin and tested different connections (FTP, SSH, SFTP). Everything went well.
The problem is when the HDMI cable is pluged in as it was on installation, the device boots without any problem. Then if the HDMI is disconnected during reboot or startup nothing happens, the device boots to bios shell (i think). Unable to login or doing anything.
Hope somebody can help!
