There are kernel drivers for this device, but they are still in development. Most people report the best results with ndiswrapper. Step-by-step instructions are provided in this HowTo.

If you want to use the older BCM43xx drivers, see this HowTo.

The newer driver is the b43 driver, which is included in kernels starting with 2.6.24. For more information see http://linuxwireless.org/en/users/Drivers/b43.

You may find it necessary to use an older version of the FW extractor software. To use the b43-fwcutter-009 instead of the b43-fwcutter-011 firmware extractor mentioned in the article and the Dell Inspiron 1520 How-TO

Download, extract the b43-fwcutter-009 tarball and build it per the instructions at http://www.linuxwireless.org/en/users/Drivers/b43.

The tarball is locate here:

wget http://bu3sch.de/b43/fwcutter/b43-fwcutter-009.tar.bz2

Sound

To activate the microphone you have to enable all Capture and Mux channels (left and right) and also set Input Source to Front Mic.

ACPI

The ACPI DSDT table is broken. However, the stated goal of the Linux ACPI project today is that Linux should run on unmodified firmware. (see Linux/ACPI project). If you have problems you should report them upstream to get them fixed.

Alternatively you find a fixed (by dev_zero) dsdt.asl here.

To hardcompile your new DSDT into the kernel, follow these steps:

• Download the dsdt and extract it:

# gunzip Dell-Latitude-D630-A03.asl.gz

• Then install iasl.

# emerge -v iasl

You'll need iasl (Intel ASL compiler) to compile the ASL source you get from http://acpi.sourceforge.net .

• Then to compile your newly aquired DSDT, do:

# iasl -ic Dell-Latitude-D630-A03.asl

And now, this isn't essential, but I copied the Dell-Latitude-D630-A03.h into the kernel source.

# cp Dell-Latitude-D630-A03.h /usr/src/linux/include/acpi/dsdt.h

• Time for some kernel configuration:

Make sure you uncheck "Select only drivers that don't need compile-time external firmware", under "Device Drivers" -> "Generic Driver Options".

Device Drivers  --->
    Generic Driver Options  --->
        [ ] Select only drivers that don't need compile-time external firmware"

This makes the "Custom DSDT Table file to include" option appear under, "Power management options" -> "ACPI (Advanced Configuration and Power Interface) Support". Fill in the path to where you copied/compiled your DSDT's headerfile.

Power management options  --->
    ACPI (Advanced Configuration and Power Interface) Support  --->
        [*] Include Custom DSDT
        (/usr/src/linux/include/acpi/dsdt.h) Custom DSDT Table file to include

Only thing left now is to do some make-magic and copy the kernel image inplace and reboot.

NOTE: If while compiling the kernel you get and error about "amlcode" try to compile the asl file with -

# iasl -tc /path-to-.asl file/filename.asl

This will create a ".hex" file in the path you compiled it in I wrote the full path and file name of this hex file in the kernel and it worked for me.
