Hi Elvin,
Thanks for your replay. My PCIe device is FPGA Based and it takes around
300us to configure the FPGA and will visible as a PCIe device. In UEFI
BIOS, when Option ROM drivers will execute? is my FPGA delay is causing
any effect. Please see my comments are inline.
Thanks

Here I am writing just option ROM driver for my PCIe Device. For testing I
connected my PCIe device to Intel server.

Yes, MY option ROM is mapped to flash inside PCIe Device.

Thanks Elvin. I will update this info also.
