I'm having trouble getting a dual PXI-1095 chassis system to boot (Both in Daisy Chain and Star topographies). I am running a Dell Precision 7875 with a PCIe-8398 card. Chassis 1 has a PXIe-8399 Card and Chassis 2 is running an PXI-8398 Card. I can successfully boot to one or the other chassis but cannot get the system to boot with both systems attached. I've made sure power on sequencing was done correct. Removed all the cards from the system. Tried in Star Topography in an X8 configuration as well as Daisy Chain (Intended setup) with the PCIe-8398 to PXIe-8399 and PXIe-8399 to PXIe-8398. Any time both systems are attached my computer fails to boot and flashes 3 amber 2 white error on the power button indicating a PCIe error. In reading this seems to be an enumeration issue or bus issue but the Dell Bios for the 7875 (Made sure its the latest) has no option for me to change related to these feature. I've already disabled secure boot and other settings i can find. Please help!
