Wireless BCM4312 with the 3.6, 3.7 and 3.8 kernel

Broadcom Chipset BCM4312 As a follow up to , I’ve also tested the Broadcom hybrid driver with the 3.6, 3.7 and the soon to be released 3.8 kernels with success. There have been no major changes that should effect the operation of this driver.

To verify that everything is working as expected on the software side, when modprobe or insmod wl, you should get a similar dmesg output:

[ 307.560347] lib80211: common routines for IEEE802.11 drivers
[ 307.560353] lib80211_crypt: registered algorithm ‘NULL’
[ 307.564524] wl: module license ‘unspecified’ taints kernel.
[ 307.564529] Disabling lock debugging due to kernel taint

Properly ripping DVDs and adding subtitles in Ubuntu

dvd::ripThere are occasions where you legitimately need tools to help that would otherwise be considered the domain of “pirates” and “ne’er-do-wells”. In this particular scenario, my grandparents send a DVD from the United States (Region1) to us in Belgium (Region2). Not only will the DVD not play back on a region locked DVD player, there are also no Dutch subtitles.

There are however technological solutions to this type of problem, including such programs as dvd::rip, vobsub2srt and a few websites dedicted to crowdsourced subtitles.

Upgrade Samsung Galaxy Gio to CyanogenMod 7.2

Going from 2.3.x (Gingerbread) to CyanogenMod 7.2 (Gingerbread) is surprisingly simple unlike upgrading from Froyo. I’ll go into more detail below, but there are two necessary bits: an updated recovery rom and a custom (non-official) CyanogenMod rom. This version of CyanogenMod is specific to the Samsung Gio.

Before upgrading your Samsung Gio, you must first be running at least 2.3.x (Gingerbread) before continuing because of the use of ext4 instead of rfs. Please follow my upgrade guide “Upgrade Samsung Galaxy Gio from 2.2.x Froyo to 2.3.x Gingerbread” first.

Warning: Caveat emptor – While I used to this process to update my phone, I take no responsibility if you brick your phone. Be sure to back up anything you wish to save, this procedure works best when your Gio is fully wiped of data.

The case of the non-booting USB thumb-drive and the Dell R620

Awhile back I wrote about ‘Doing battle with a Dell R620 and Ubuntu‘ where I touched on the fact that booting from USB thumb-drive was a painful problem. In short, the same USB thumb-drive that would work in the R610 would not work in the R620.

It comes down BIOS support for USB and how it is handled. On the R610 there are 3 options: ‘auto-detect’, ‘floppy emulation’ and ‘hard drive’. Auto was hit-or-miss, floppy would not work but ‘hard drive’ worked every time. On the R620 there are no options so I can only suppose that it supports ‘floppy emulation’ upon detection of a USB thumb-drive.

Dell DSET on Ubuntu 10.04 and 12.04


Dell System E-Support Tool (DSET) is an informative tool used by Dell’s support engineers to help diagnose problems for their clients. It is almost a requirement now and Dell usually refuses to continue support without a DSET report.

The problem is that DSET is only supported on Redhat and SuSE Linux and there isn’t any information on how to get it running in Ubuntu. I’ve assembled a rough guide on how to get DSET up and running on Ubuntu 10.04 and 12.04 and it is tested against a Dell R610 and R620.
