Hi Vaclav,

Could you try this just-merged patch and see if it fix your problem?

I spent some time Googling, comparing Smolt profiles, reading S205 Hardware Maintenance Manual [2]  and analysing the BIOS updates. It seems, that all S205 are based on AMD platform called "Inagua" (E300, E350, E450), use two types of Wi-Fi cards (RaLink RT3090 and AR9285), various combination of SO DIMMs (2 x 1GB, 1 x 2GB, 2 x 2GB), different sizes of hardrives and different keyboard layouts; so overall there are pretty much the same.

The current situation is pretty bad - problems with UEFI booting (the only possibility)[4], impossibility to switch the power off, failing brightness control - and without a functional network connection for a start, it is better to throw it out of the window.
