[mythtv-users] HVR-950Q rev B4F0

I've been using the HVR-950Q USB sticks with great success
for ATSC reception with Mythtv.  The ones I have are
all revision B3F0 (from the kernel log messages).

So I often recommend these tuners to friends.

But two of my buddies got revision B4F0 tuners,
and they wouldn't tune at all in Mythtv.

Today I had a deeper look at things, and the rather odd fix
turns out to be going into the BIOS settings and setting
"Plug and Play O/S Installed" to "YES",
as well as setting the mode for the onboard IDE controller to "AHCI".

I suspect only the former was necessary, but the latter setting
is the preferred mode of operation for SATA so..

Any.. if you're having issues with a USB tuner,
try changing some BIOS settings.
