Hi,
I have a Lex 3I380D-D90
Bay Trail-D J1900 2.0GHz (Burst to 2.41GHz) (Quad Core)
Intel Bay Trail-D J1900 chipset
Insyde UEFI BIOS
* 4 x Intel I211AT 10 / 100 / 1000 Mbps
* 1x PCIe Mini Card (USB + PCIe + SIM card)
* 1x PCIe Mini Card (USB + mSATA Gen II)
Running 1.2RC5 I see all four NICs. From RC6 (newer kernel?) only eth0 is present.
```

so all is OK at this level.
This is where the difference is:
sh system ke | grep Ether
