 +Oh, and there is UEFI boot in the BIOS. I was very disappointed to see it and to be honest, I've violated my pledge not to buy any UEFI device. 
 +However, this UEFI thing does nothing so far. Perhaps it will one day, at one point, with newer BIOS? Who knows. I'm just letting you 
 +know.
 +
 +===== Running GNU/Linux =====
 +
 +I've started with Slackware. However, since I was constantly failing at WiFi part, I've decided to move to Kubuntu(only to find out it's 
 +the same). Since almost everything worked, I can't give you too much advice what-where-how. But since it has nVidia GPU, you can either 
 +go with Nouveau or nV's proprietary driver. I'm rolling with Nouveau since I don't need OpenGL. Don't forget to build your 
 +kernel with support for switchable graphics(CONFIG_VGA_SWITCHEROO ?). As for sound card, Alsa or 
 +OSS(no, it is not deprecated). Touchpad is Synaptics(or so I guess), webcam is Lenovo's EasyCam and will require V4L. USB 3.0 is XHCI.
 +
 +==== Ethernet ====
 +
 +I thinks I've used this [[http://askubuntu.com/questions/157223/12-04-does-not-detect-eth0atheros-ar8162|link]] to fix the issue with ethernet not 
 +being present. I found it rather sad this driver was not yet in kernel after a such long time. But well, it happens. Some information is 
 +[[http://www.linuxfoundation.org/collaborate/workgroups/networking/alx|here]] as well.
 +
 +In case of unavailability of the site, I'll copy paste information there:
 +
 +<code>
 +tar -xvf compat-wireless-2012-02-28-p.tar
 +cd compat-wireless-2012-02-28-p
 +scripts/driver-select alx
 +make
 +make install
 +modprobe alx
 +</code>
 +
 +
 +==== WiFi ====
 +
 +WiFi works out of the box, but only for channels 1-11 and only with proprietary(?) drivers. I had no luck to get channels 12-14 operational 
 +nor I had luck with mainline drivers(not even WiFi scanning).
 +
 +Anyway, some information is [[https://wiki.archlinux.org/index.php/Broadcom_wireless|at ArchLinux wiki]]. Less said about this hunk of crap, the better. In other words, I suggest not to bother with this and either get hold of a solid USB WiFi adapter(which is challenging on its own and depends on luck, but I was lucky) or replace it with some Intel WiFi adapter at additional cost(which, in my opinion, is worthy, because Intel WiFi cards just work in Linux).
