Installing Slackware64-13.0 via USB

The Intel Atom N450 has 64bit support so slackware64 (or any other 64 bit distribution) should work just fine. As the W21 has no optical drive (it's a netbook) you must install your distribution using USB. Do not forget to activate usb-boot (called 'external device') in the BIOS (Hit F2 at startup)

Upgrade to Linux >= 2.6.33

Xorg and the sony-laptop module will need a very recent kernel. Do not even try to fix things with anything below 2.6.33 You can download my .config for linux 2.6.33-rc7 from here

Upgrade xf86-video-intel

The 'Pineview' GPU is supported since xf86-intel-video 2.10.0, you can download an updated package for slackware64 from my slackware64 repository
# wget http://www.blinkenlights.ch/slackware/slackware64/13.0/x/xf86-video-intel-2.10.0-x86_64-1_au.tgz
# upgradepkg xf86-video-intel-2.10.0-x86_64-1_au.tgz
# sync
# startx ## Xorg will autodetect everything itself.


HSUPA Modem (Gobi 2000)

The Gobi 2000 WWAN modem works but needs some love to get it running.
First you should check if you can see the modem using lsusb:
Bus 003 Device 002: ID 0489:e00f Foxconn / Hon Hai
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 004: ID 04f2:b15c Chicony Electronics Co., Ltd
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 05c6:9225 Qualcomm, Inc.
If the modem does not show up, something is wrong with your sony-laptop module. (did you upgrade to kernel >= 2.6.33 ?)

Obtaining the firmware

The Gobi 2000 modem is 'dumb' and will not operate without the correct firmware files. You can copy the existing files from your Windows 7 installation: they should be stored at C:\Program files\QUALCOMM\Images\Sony\. You will need 0/UQCN.mbn and both files from the UMTS folder (amss.mbn and apps.mbn). Copy all 3 files into /lib/fimrware/gobi:
# cp UQCN.mbn amss.mbn apps.mbn /lib/firmware/gobi

Did you delete your Windows 7 installation? Don't worry: You can get the files from sonys driver package:
# wget ftp://ftp.vaio-link.com/PUB/VAIO/ORIGINAL/WIRELESS_WAN_DRIVER_QUALCOMM_1.0Z2Q309_1.1.11.ZIP
# unzip WIRELESS_WAN_DRIVER_QUALCOMM_1.0Z2Q309_1.1.11.ZIP
# cd Wireless\ WAN\ Driver\ \(Qualcomm\)\ 1.0Z2Q309\ -\ 1.1.11/
# cabextract cabextract GobiInstaller.msi

You'll end up with about 70 cryptic named files. So let's try to find the needed files: we are after Sony/UMTS/* and Sony/0/UQCN.mbn.

Tada! :-)

Patching qcserial

The qcserial in linux 2.6.33 does not support the gobi 2000 out-of-the box. You need to apply this patch (qcserial.diff). (based on this patch).
After reloading the new module (make modules ; make modules_install ; depmod -ae ; rmmod qcserial ; rmmod usbserial ; modprobe qcserial) you should get a /dev/ttyUSB0 device.

Installing the firmware loader

Download and extract gobi loader and apply this patch (gobi_loader.diff) (note: this patch was stolen from http://www.madox.net/blog/2010/01/06/hp5310m-un2420-wireless-gobi2000-module-in-ubuntu/)

Upload the firmware

Ok, you can now start your patched gobi_loader to upload the firmware:
/lib/udev/gobi_loader /dev/ttyUSB0 /lib/firmware/gobi

lsusb should now show a new device id for the qualcomm modem:
# lsusb|grep Qualco
Bus 001 Device 005: ID 05c6:9225 Qualcomm, Inc.


You should now re-load the usbserial driver (fixme: why?)
rmmod qcserial usbserial
modprobe usbserial vendor=0x05c6 product=0x9225

If everything went well, you'll get /dev/ttyUSB0, 1 and 2 (/dev/ttyUSB2 is the modem itself)

Dialing

The Gobi 2000 will now behave like a normal Hayes compatible modem. Use your favorite dialing application to get connected:

I use wvdial with my swisscom liberty uno simcard (wvdial.conf)
## first step: unlock the SIM (do not forget to change the pincode in wvdial.conf!) # wvdial pin --> WvDial: Internet dialer version 1.60
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: AT+CPIN="2204"
AT+CPIN="2204"
OK
# wvdial swisscom [...]
--> local IP address 10.158.155.96
--> remote IP address 10.64.64.64
--> primary DNS address 138.188.101.186
--> secondary DNS address 138.188.101.189
