Hiho
I've updated my APU2C4 to 4.6.1 because i've bought a mini pcie gigabit nic from delock with rtl8111e chipset which has not worked.
With the help of this guide
http://www.bsdforen.de/threads/pc-engines-apu2-bios-update.33587/
i did it directly from the running OPNsense system 
After that the nic has started to work, but after some time i got many ahcich0 errors and a unresponsive/self rebooting APU.
Maybe this version has bugs or i having issues with the original power supply, so i installed 4.0.11 and looking forward how it works now...

Does anyone know where i can download new bios instead of
http://pcengines.ch/howto.htm#bios
? This site is not up to date, i got the 4.6.1 by editing the url
http://pcengines.ch/file/apu2_v4.6.0.rom.tar.gz
to
http://pcengines.ch/file/apu2_v4.6.1.rom.tar.gz

But
http://pcengines.ch/file/apu2_v4.6.2.rom.tar.gz
or
http://pcengines.ch/file/apu2_v4.6.3.rom.tar.gz
doesnt work.
And here are only the sources available...

I have a general question. Do we need an update for the meltdown or spectre issue? Is the apu board affected?
Unfortunately I haven't tested it yet. I still use an APU1 board.

[tillsense]

Hi all,

that's a question for amd. pcengines has a statement here: https://www.pcengines.ch/spectre.htm
