I am having problem booting an HP Z210 with two quad PCIe 2.0 cards using either E1G44ET or E1G44HT.
One card boots fine. When I add 2nd card the system will not boot. I have tried different cards in different slots. I can get the PC to boot with any of the cards in any X8 or X16 slots. However, any 2 cards will never boot.
The Z210 has 7 slots - 5 PCIe 2.0 (two X1, one X8 and two X16). There is no video card. I have tried 1 card in the 3 compatible slots successfully. The Z210 will boot with either card in any slot. However, when I plug a second card in the system will not boot.
The E1G44ET or E1G44HT are both X4 and the 3 compatible slots are at least X4 electrically.
Check with HP for BIOS updates for your system. I have not heard of this particular issue, but I recall other PCIe slot issues that have been resolved by BIOS updates. Let us know if a BIOS update fixed the issue for you.
I have exactly the same Problem and I can confirm that it is still not solved in the latest BIOS version (01.35 Rev. A, 21 Feb 2012). It definitely is a Problem of the HP z210 Workstation because in a different Computer the two cards work just perfect. I already tried to disable the Boot Agent but this piece of s... engineering art seems to ignore it (again this works perfectly on the other Computer).
I was wondering if the thread creator found a solution to this or if there is anything else I can try?
Oh well, here comes the solution. It seems to be a BIOS Configuration Problem.
Go into BIOS by pressing F10 on startup (don't start with the two cards inserted or else you will not even be able to get in the BIOS), navigate to the "Advanced" Menu, select "Slot Settings". A blue Window pops up where you can enable or disable "Slot X Option ROM Download". Disable this Option for the Slots you want to put in your two cards. I have no Idea what this Option does but now my Workstation is booting and the cards are working.
Please keep in mind that I'm running the above mentioned BIOS version and I have disabled the Intel Boot Agent on both cards with the Bootutils (I don't know whether this makes any difference or not).
Hope this helps others with the same problem.
