Great Questions!
OS is Windows 2012 R2
Drivers are WinOF 4.9
Firmware was a custom burn version above 2_9_1000, that was working initially. 2.10.720 I believe.
I have two MHQH19B-XTR's at the same firmware and drivers, in two identical machines running Win 2012 R2, without issuee.
The primary difference is that the XTR's are not mezzannie PCI cards, and the problem cards are.
Both servers started at a clean install of 2012 R2. One of the servers has since had a clean install, with the non-working card installed from the beginning.
Usually, windows has no problem detecting and loading generic drivers, on clean install.
However, my cards are not seen at all anywhere on the system.
So my questions are:
Is my mezzannie slot damaged or did both cards die?
If the firmware is goofed up, and I short the jumper to ignore the flash, should I be able to see the card via the mst utility? Because it doesn't show up..
mst does not show the adapter at all, so I don't believe this is a case of windows driver issue. PCI-Z also does not show any cards on the PCI bus, but all the same PCI equipment shows up otherwise.
The problem began after some physical maintenance to the server that included de-racking it and doing some hard drive stuff internally. While I don't believe damage to the slots occured (can't imagine what might have done that), it is suspicious to me that the cards failed to work from that point forward.
I don't know if bad firmware coupled with a cold-start can cause the cards to lose their mind?
And I don't know if the cards should show-up in the mst utility if they are put into "ignore the flash" mode...
I have two machines that I can move the cards too, to isolate and see if it's a slot problem or a card problem, but those machines need a little bit of work to fit the card in there, so I wanted to make sure there was nothing else I could do to see if the cards are still alive before I do that.
I don't have an i2c setup to connect to that port at this point, but I'm open to it if that's the only way to figure this thing out.. since these cards are not cheap!
Thanks for any information!
