Hi,
WinTV-HVR-2200 used SAA7164,which has PCIE1.1 interface.
Our products use SAA7160,which has PCIE1.0a interface.
About 1 year ago when Intel Sandy Bridge platform was released AMI
(American Megatrends Inc) made very serious bug in their first BIOSes
with Sandy Bridge support regarding proper PCI-Express support, which
was fixed and almost all (at least the major and good brands) of
motherboard immediately provided BIOS updates that include the fix. so,
the BIOS bug is as follows:
the PCIe Root complex (North bridge of the chipset on the motherboard)
and the PCIe end-point (in the particular case SAA7160 on TBS boards) do
not finish the training sequence (TS1,TS2) and the bus traffic between
the Root complex and the end-point are keeping busy in retrain loop.
that is caused, because North Bridge register (TLS ) "Target Link Speed"
setting doesn't auto change from 5Gb/s to 2.5Gb/s, which is required for
1.x backward compatibility
so, in very short the root cause of the problem is that their BIOS sets
the TLS always to 5Gb/s and it doesn't auto-change it to 2.5Gb/s, which
is necessary for PCI-Express 1.0a bridges and when such bridge are detected.
That is not TBS fault and is major bug in the motherboard BIOS that affects wide
range of PCI-Express boards.So you have to update the latest BIOS for your motherboard or contact with Dell.
Regards!
