Apparently it seems that mikrotik won't boot with AR5212/5213 based card on S3G. I tried planet, alfa, cm9 with minipci adapter and had no luck. The strange thing is that TP-Link cards with the same chipset work flawless, both ar5212/5213 and ar5413...

I've tred v2.9.51, v3.11 and the situation is the same - mikrotik starts booting but there is no "beep beep" signal at the end. The machine just freezes. Without pci nics mentioned above everything works fine (tp-link only).

Just to mention - on windows everythign works fine, too
