Hi:

The forum has been having issues with e-mail notifications of a reply to a post, so I am hoping you see this...

I don't know if you saw my last reply regarding a solution to your issue that I found...this is promising...

I have been searching around the workstations forum and it appears like you wrote that a lot of folks have this problem.

However one guy was able to resolve it by a very unconventional method...see this thread.

Here is the reply I am referring to...

We did, but it didn't change anything... BUT! We just solved it:

We took the z400 to a hardware shop where they told us that the CMOS reset button almost never works in HP workstations (?)   Then we put an old PCI (not express) graphics card in and indeed, the z400 recognized it, we were able to go into the Bios and put the setting of the two PCIe slots back to normal.  

So everybody, be warned: if you mess with the PCIe settings, the only way to change it back is by hooking up an old PCI VGA card.
