Linux

The M3A78-T has an ATI HD3300 onboard videocard.

I you are trying to install debian with the regular radeonhd driver, your X server will not start because this chipset is not yet managed by the driver. You will have to choose to use the VESA driver, or recompile the radeonhd one.

I choosed the 2 option, and here are the steps to do so.

Install all the related packages
apt-get install ibtool libdrm-dev xserver-xorg-dev xorg-dev xutils-dev git-arch
git-core libglc-dev

Get the last version of the code using
git clone git://anongit.freedesktop.org/git/xorg/driver/xf86-video-radeonhd

Move to the xf86-video-radeonhd directory and start autogen.sh then make.

The make install command did not worked for me, so I copied the file src/.libs/radeonhd_drv.so directly under /usr/lib/xorg/modules/drivers.

I was not able to start X with the radeonhd driver before the install,
and I'm now able. So I think it's working.
