I have a BT Voyager 100, so hopefully this will be the same driver.
First off, make sure that you have make and gcc installed on your SuSE system, as you will need to compile beta-drivers.
Now go to:
http://eciadsl.flashtux.org/download.php?lang=en and scroll down till you find the [ EciAdsl Nortek ] section. Now download the bz2 file, and reboot to linux (assuming you're using windows to write the messages on here).
Now copy the bz2 file to somewhere like /usr/src and start a shell prompt.
You will need to type the following in (im not 100% sure about directories):
Code:
tar -jxvf eciadsl-usermode-0.10-nortek-alpha.tar.bz2
cd eciadsl-usermode-0.10-nortek-alpha
./configure
make install
make cfg
cp GS7470_SynchFiles/gs7470_synch03*.bin /etc/eciadsl
(Remeber that capitals matter).
Now you have to configure the driver with settings that BT gave you.
The VPI is 0 and the VCI is 38. The password can be anything you want, I usually just use BT. When it asks you to choose modem, type 10 and chipset is GS7470. When choosing synch files, you want gs7470_synch03.bin.
Hope this helps, post back if you have problems

Edit [24/05/05]: I made a mistake in the synch files. Aparently for the Voyager 105 the correct synch file is _synch03.bin, whereas for the 100 its _synch01.bin. Sorry for any problems this caused anyone.
