Hi all,
Attached is a patch I had to use to get the 0.9.x trident drivers to
load on my Jaton Sonicwave. I'm not an AC'97 expert, but the 0.5.x
drivers didn't used to check for this reset condition.
The soundcard itself appears to work perfectly happily with this mod
to carry on regardless if the check fails, but I assume it was added
for a reason!
Cheers,
Mark
