+= Overview =
+* CPU: Intel Core 2 Solo U3500 @ 1.40GHz (speeds: 0.8, 1.2 and 1.4GHz), 3MB L2
+* Screen: 1366x768 LED
+
+= BIOS versions =
+* 1.10 - average ACPI temperature around 34°C, good GL playing
+* 1.20 - average ACPI temperature around 39°C, good GL playing
+* 1.31 - big slowdown in X windows from time to time, GL games with annoying slowdowns regularly
+
+The most recent BIOS updates (1.20 onwards) come with a DOS flasher; older come only with a windows flasher. I used a [http://www.pcengines.ch/freedos.htm freedos image] stored in a USB flash memory to boot freedos and flash the BIOS.
+
+= Drivers =
+All provided in linux 2.6.32 kernels.
+
+Linux 2.6.29 has problems at least with the wire ethernet card (Attansic Technology Corp. Device 1063). Loading and unloading the ethernet card driver module (atl1c) helps getting a working link, although it will change from eth0 to eth1, eth2, or another interface name.

+= X settings =
+
+== Backlight ==
+Having disabled Kernel Mode Setting for the i915 kernel drm module (kernel parameter ''nomodeset''), use ''xrandr'' to set:
+ xrandr --output LVDS --set BACKLIGHT_CONTROL combination
+ xrandr --output LVDS --set BACKLIGHT 300  # ~1000, max light.
+
+If those steps make your mouse cursor not appear, switch to another VT, and then back to X, and it will come.
+
+== Synaptics pad ==
+I like the pad speed set by:
+ synclient MaxTapTime=0 MaxSpeed=1.12 MinSpeed=0.6 AccelFactor=0.001 VertEdgeScroll=1
+Install the ''xf86-input-synaptics-1.2.0'' for ''synclient'' to be in your PATH.
