MSI PR201 and linux: bluetooth, fingerprint, Intel video, Intel audio and card reader

Hi everybody,

today I'm going to write about some tricks to fully handle MSI PR201 features. As comes out of the title we are going to treat 5 main areas: bluetooth dongle, fingerprint sensor, Intel Graphics, Intel audio and MSI PR201 is a small but complete notebook, it comes in a small and lightweight chassis, with a 12" screen. It has a Montevina chipset, so it won't support latest Intel processors (i5, i7 etc), but can run up to the T9900 or X9100 with 3,1GHz clock. The ram supported is DDR2 up to 8GB. Our hardware is going to be:

Device 002: ID 0db0:a97a Micro Star International Bluetooth EDR Device
Device 002: ID 147e:1000 Upek (fingerprint sensor)
VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller
Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller
?? Card Reader ??

Boot time tuning chapter 5th: Timing

Hi everybody,

as promised I'm here again with another chapter about boot tuning. Last time I made a little step back to improve my system reliability, today I'm moving forth again, with no renounce of course!

The solution I was trying it is very customizable, but I'm going to explain as well as I can how can you achieve the same degree of optimization on your box. Our requisites are a text editor, bootchart and if you are running gentoo we will use eselect tool. If you don't have bootchart you can find a guide how to install it here or googling around.

As always I suggest you to give up if you don't know what you're doing, unless you try it on a "testbox". I don't take liability of any consequence.

Boot time tuning chapter 4th: Reliability

Hey,

today I'm making a little step back but another forward. I mean that in the last tuning chapter I was enthusiastic of my 9 sec boot time, even knowing I was on the edge of the blade. Actually nothing bad has happened, I was even able to cut away another second.

I did optimize booting levels and made some order in my xorg.conf. Maybe some little extra is given by the latest xorg version, which I installed in these days. At the very end of my optimization I was able to boot in 8s... but sometimes I was not able to boot. So here is the detailed story.

Multidimensional matrices operations: Matlab mtimesx

Hi guys,

today it's the first time I'm writing about something concerning the world of engineering. In particular we are talking about matlab: an awsome platform for computing. Imagine a swiss-knife with easy high-level programming language, GUIs, rapid and optimized libraries, data importing, terminal board connection, graphig drawing, 3d animation, system terminal interface and lots of toolbox developed by users from all over the world: this is Matlab.

When I heard the first time that name at university I was not happy to learn another programming language more than C++, but time made me change my mind. Now that program is the base to do any sort of thing in my working environment. A brief look at my work is some 3-d processing on a set of slices coming from MRI (Magnetic Resonance Imaging), and believe the results are amazing.

New Adobe Flash support for 64 bit system

Hi guys,

Seems finally the day has come. One of the most desidered ad still not available features of 64bit os was the Flash-reader plugin. Still on Gentoo-x86_64 it was the default choice to install the 32bit plugin with 32bit precompiled libraries and nspluginwrapper. This sounds not easy and indeed it is, at least conceptually. The major cause of the choice was of course the lack of a 64bit plugin. Maybe some opensource were available, but you know those work correctly on 1 content over 10.

Adobe released the Adobe Flash Player "Square" on sept 27th, but gentoo portage have already included beta version few months ago. It comes with beta version 10.2, here comes the steps to install it.
