I got a feedback from TBS about this issue.
Seems to be a BIOS Bug in the Intel mainboard:
I assume that his bug is also applicable from the DH77DF Bios.
So my request to Intel is: please create a running Bios update that solves this issue ... and btw no the same bull**** like with the 95 bios release, which causes linux in efi mode to not even boot anymore...
would be nice if someone from Intel could comment this behaviour of the PCIe slot ... or even better solve this issue with a bios upgrade...
Would be fine if PCI 1.x devices will also run with this mainboard:
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!"

The TV-Card Technisat Skystar 2 eXpress HD isn´t working with the DH77DF.
The card works fine with Intel chipset X38 in the PCI-E x16 slot.
Contacting the Intell support didn´t aim a solution. The said that the card is not compatible.
I think something is going wrong with the BIOS of the DH77DF.
i am also sure it is the bios of the DH77DF.
Have you check the link... ?
I guess they only focused on PCIe2.x or higher devices and forgot the PCIe1.x devices.
Very bad mistake from Intel.
I really hope they read this and check the BIOS .... PLEASE
I checked the link and i agree with you totally.
Technisat can´t sell their TV-Card without having the PCI-Express logo but Intel can do that without the logo?
I hope Intel will solve this issue in a short time!
ok, nice, so i propose to push this posting until we get a feedback from Intel. ok?
This might be the right way for us!
Can yout test other PCI-Express 1.0 cards. I mean network and/or grahic cards to confirm this training issue?
As i mentioned in my email, i only have a Nvidia GT9500 which is not PCIe1.x i guess.
I will try to get more devices.
@Intel : when do you provide an bios update?
i have exactly the same behaviour with my DQ77KB (newest Bios 0040)
PCIe X1 Tevii DVB-S2 Tuner S471 is not regognized
BIOS -> PCIe not populated
Card is new and works well on an DH67BL!
nice, so if we get more people with the same issue, we may have a chance to push Intel to solve this.
bump for today ->
Dear Mr.Intel, please solve this issue.
I think the Series 7 Chipset should be compatible with PCI-Express 1.0! It is not a hardware bug, only a BIOS bug.
More people have the same issue like we have.
Intel said only the card is not compatible with the board and that is it? I think that isn´t the right way! Please solve it!
I had reported this PCIe compatibilty issue since 6th of June and guess what. My Intel representative just simply close the whole case without any solution being offered.
Their so call solution :
a) They advice me to buy PCIe card that was manufactured after their 7 series board is produced. What a joke.
b) Not surprisingly they direct me to the website below as though those are the only hardware available on the planet earth that works with their motherboard :
c) Intel representative ask you to contact your TV tuner manufacturer (Try to push the problem away)
d) Send your TV tuner to Intel for testing. (Even after they tested it and it was proven it cannot work what can they do that is the question)
Bottomline they just want to push the problem away. With so many different brands of PCIe TV tuner cards not working definitely this is Intel's fault 100% for sure.
What a bad joke, i am already try to spread this isse with the intel boards over the whole i-net.
Keep pushing Intel !!!!
Stay together and kick their a** until they react.
