MSI Wind U200

Technical specifications of MSI U200 - S2743W7P

 * Display: 12.1"WXGA (Glare Type)
 * Processor: Intel ULV SU 2700, (2M Cache, 1.30 GHz, 800 MHz FSB), EM64T
 * Hard Disc: SATA 320 GB
 * Memory: 2x2GB

Resources of information and help

 * Intel SU2700 link 1 or Intel SU2700 link 2

Installation

 * The SU 2700 processor is 32bit with the ability to emulate (mostly) all 64bit instructions (EM64T flag). Use the AMD64 installation medium to facilitate the addressing of all the 4GB RAM it is shipped out with.
 * Create bootable USB device from other Linux system using for example the tool sys-boot/unetbootin or by hand following the instructions of Gentoo LiveUSB
 * Keep the USB device plugged-in and enter the BIOS to select it as first of the boot-sequence
 * There are 4 partitions given by the manufacture. I suppose the first two are containing the recovery data so I left them untouched and installed Gentoo at the residual disc space.
 * CHOST="x86_64-pc-linux-gnu"
 * CFLAGS=?
 * It is difficult to find information about proposed settings for this processor. Any ideas?
 * "-02 -pipe -march=nocona -mssse3" <-- is working fine
 * CXXFLAGS=${CFLAGS}
 * VIDEO_CARDS="intel"
 * INPUT_DEVICES="evdev synaptics"
 * USE="what you want + acpi hal laptop mmx sse sse2"
 * Kernel: (see below item hardware configuration)
 * Due to a problem intending to install xorg-server it was necessary to remove sys-fs/e2fsprogs and sys-fs/e2fsprogs-libs.
 * After installation of Gnome the application menu didn't appear. Fix it with: ln -s /etc/xdg/menus/gnome-applications.menu /etc/xdg/menus/applications.menu

Advices

 * Don't forget to activate the webcam with Fn+F6
 * It is necessary to build uvcvideo as module. Otherwise the webcam wont work.
 * hal (hardware abstract layer) is necessary for a lot of applications. -> /etc/init.d/hald start
 * to use it as user: adjust the permissions of /dev/video0. For example media-video/cheese needs read and write access: chmod 666 /dev/video0

Suitable (tested) software

 * media-video/cheese - Gnome application to take pictures and videos from your webcam
 * net-im/skype
 * net-voip/ekiga - choosing V4L2
