Making Ubuntu 8.04 work with the HP Thin Client t574x

The network chipset provided by this Thin Client is a BCM 57780 which is not supported by default by Ubuntu 8.04.

In order to change that you can download a more recent driver for the Tigon3 either from the Broadcom Web site (110g at time of writing) at http://www.broadcom.com/support/ethernet_nic/netlink_k57.php or previous versions as preserved on the HP site at ftp://ftp.hp.com/pub/softlib2/software1/pubsw-linux/p122860230/

To make compatible drivers for the Ubuntu kernel, the best approach is to create a chroot of Ubuntu 8.04 to have a clean install env.
You can use debootstrap for that. As the project Lead of project-builder.org, I used my rpmbootstrap command through pb which did that for me:

$ pb -p pb -m ubuntu-8.04-i386 newve
Project: pb
Action: newve

$ sudo cp /etc/hosts /home/rinse/ubuntu/8.04/i386/etc/hosts... OK
Fixing permissions... OK

Then you can go into the chroot to prepare it for being a good build environment (in particular copying in it the .config file coming from the Ubuntu 8.04 live CD under /boot/config-2.6.24-26-generic on a USB key):

$ cp /media/USBDISK/config-2.6.24-26-generic /home/rinse/ubuntu/8.04/i386/tmp/.config
$ sudo chroot /home/rinse/ubuntu/8.04/i386/ /bin/bash
# mount -t proc proc /proc
# apt-get install linux-headers-2.6.24-16-generic linux-source-2.6.24 libncurses5-dev gcc unzip

# cd /usr/src
# tar xfj linux-source-2.6.24.tar.bz2
# ln -sf linux-source-2.6.24 linux
# cd linux-source-2.6.24
# mv /tmp/.config .
# perl -pi -e 's/EXTRAVERSION = .3/EXTRAVERSION = -26-generic/' /usr/src/linux/Makefile
# make clean prepare scripts

Now you can use that tg3.ko module with insmod into your live CD and have network support !
Of course, that method is generic enough that you could use it for many other cases.

    Fun to have a post about Ubuntu on Planet Mandriva…

      I was not thinking that all my Blog articles would appear on Planet Mandriva ! I never register myself (AFAIK) for that to happen. If that is a problem for readers, I’d recommend only using articles which have the tag “Mandriva” as a filter. Indeed I even found former articles dedicated to Music which have nothing to do there😦
