Hello, I am trying to replace the PXE Firmware of my Intel I217-V network card. But since it´s an embedded network card the firmware is part of the bios. I have already built the required iPXE rom for my network card. But the guide on the etherboot documentation only refers to modifying a AMI BIOS(etherboot.org/wiki/amibios). Using the "Phoenix/DELL/EFI SLIC Mod v2.66" I have found out, that my server is using a “EFI/ Insyde BIOS (Dell HDR)” Bios. But so far I have not been able to extract the HDR file since the latest update is shipped as an exe and does not accept any of common extraction arguments. I could attached only the ipxe rom I built since bios is with 9MB too big for the forum. The latest version "PET20A12.exe" be found at www*dell.com/support/home/en/us/debsdt1/product-support/product/poweredge-t20/drivers. Any help would be greatly appreciated.
