The patch titled
MSI-K8T-Neo2-Fir OnboardSound and additional Soundcard
has been removed from the -mm tree. Its filename is
msi-k8t-neo2-fir-onboardsound-and-additional-soundcard.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
From: Johannes Goecke <goecke@xxxxxx>
On the MSI-K8T-NEO2 FIR ( Athlon-64, Socket 939 with VIA-K8T800- Chipset
and onboard Sound,... ) the BIOS lets you choose "DISABLED" or "AUTO" for
the On-Board Sound Device.
If you add another PCI-Sound-Card the BIOS disables the on-board device.
So far I have a Quirk, that does set the correspondent BIT in the
PCI-registers to enable the soundcard.
But how to ensure that the code is executed ONLY on excactly this kind of
boards (not any other with similar Chipset)?
