got a new DH77DF and it refuses to recognize 2 of 3 PCIe TV DVB-S2 card in its PCIe slot.
This cards even don't show in the bios where you can check which slot is populated. This board is a Mini-ITX so i have only one slot to try.
- TBS DVB-S2 6922 -> NOT recognized in PCIe slot
- TEVII DVB-S2 S470 -> NOT recognized in PCIe slot
- DVBSky DVB-S2 S950 -> recognized in PCIe slot
My intention was to get the TBS card running, i only tried the other for testing.
I have several other boards from Asus were ALL cards are recognized well.
I am quite disapointed by Intel again, cause it is my second time i got a Intel board and their boards are mainly causeing trouble.
Of course i could buy another board, but the DH77DF is the only S1155 board on the market with a HTPC header for CEC devices.
I also tried to upgrade to latest bios, but this has the bad effect that linux isn't booting anymore, at least in UEFI mode (which was no problem with the original first bios version). Anyway the bios upgrade didn't change the fact that the TBS DVB card wasn't recognized.
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 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.
