Hey all,

i´ve already another SSD - no change. Is the mainboard defect or what do you think?


Best regards

Probably just the serial console not configured correctly as documented:

Good morning Patrick,

thank you so much for your fast response - you made my day!

After modifying the BIOS settings i was able to install OPNsense as expected.

I´ll also look at the task BIOS update which i haven´t done yet.

Now i know what i´ll have to do on every older hardware if i´m onsite and there is a chance to reboot the OPNsense :-)



Thank you once again and best regards
Norbert
