Can't startup on NUC

[towa]

Hello together,
I bought an ASRock NUC BOX-J6412 (because of it's two network interfaces) and I qould run OPNsense on it.
But I can't. 

My startup from USB device ends very fast with:

atrtc0: <AT realtime clock> port 0x70 irq 8 on isa0
atrtc0: Warning: Couldn't map I/O.
atrtc0: registered as a time-of-day clock, resolution 1.000000s
Event timer "RTC" frequency 32768 Hz quality 0

after that, nothing happens.

Can someone help?

Many thanks
ToWa

Have you tried booting any other OS on the box, e.g. NomadBSD

https://nomadbsd.org/

? Just an idea....

Except trying other FreeBSD-based systems like @chemlud mentioned, I suggest (running Windows if installer needs one and) updating all BIOS/UEFI/MEI/firmware etc. everything you can.

Disable secure boot. Leave UEFI, but disable secure boot!

In case you manage to install, I suggest trying Realtek drivers available in Plugins section.

Please do speedtest on 1Gbps net and share the results, since on WYSE 5070 (older celeron) I have 600Mbps max, while on Mikrotik I have almost 1Gbps.

Many thanks for help.
I try to run nomadbsd (ZFS) and get the same error. 

After that I run Windows (10) setup from stick which works very well.

• BIOS is up to date
• SecureBoot is disabled
• TPM is disabled
• Audio Controller disabled
• COM Port disabled

But I think it's working now... I loaded BIOS Defaults so TPM, Audio and COM will be enabled and I can boot to NomadBSD and OPNsense.

@CobraPL
I doesn't need very high performance it have to be a stable and running system for special use.
