I have a working PXE boot server that launches into a WinPE image created by AOMEI BackUpper. It works on several other computers, but my Pro WS W680M-ACE SE isn't liking it.
I get "Media present, Start PXE over IPv4," it finds the server, then gives me "NBP file successfully downloaded"... and that's it - it fails out, tries the other NIC (no media present), and then goes back to the BIOS (no system is installed yet).
The logs on the PXE server show that it IS grabbing pxelinux.0 (or at least that the TFTP server is sending it).
I've tried various things like adjusting all Secure Boot options (including disabling it entirely); Fast Boot on and off; tweaked different settings under BMC Management; all with no change in results.
TFTP is on a Synology RS-2418+, and read/write permissions are set. DHCP server is a UniFi USG3. Everything involved is updated to the latest firmware/software/BIOS versions, including the motherboard.
I've tried with both syslinux 4.06 (per instructions here) and 6.03 (per these instructions), with the same results.
I found another post suggesting a similar PXE problem could be the lack of drivers for the embedded NIC... in this case it's an Intel I226-LM. I'm not proficient enough at Linux to know how I could add the proper driver after the fact, if that's what it needs (who are we kidding, I can spell Linux and that's about it).
