I have dell optiplex 5050 with BIOS Version (1.5.2) & a custom PCIe EP (Endpoint) device. Now, this PCIe EP device gets failed to enumerate often.(Only 3 out of 10 gets this device enumerated)
But when I am in BIOS-Setup for around(20 secs) & then exit from there-- then that device is enumerated always.(I read from this link: Xilinx-Forum that exiting from BIOS-Setup does complete enumeration .
Is there any BIOS Setting that can help achieve this functionality without going to BIOS first? It would be better if I can achieve this without updating BIOS version.Thanks a lot for the help.
