PCIe NIC is not visible in Unraid when motherboard NIC is disabled in Bios

[Vitek]

Hi all,

 

I bought PCIe NIC Intel i226 for replacing Realtek that is on my motherboard. When I disable Realtek NIC in Bios Unraid doesn't see any NIC, I see error that there is no eth0. When I leave realtek NIC enabled in Bios, Unraid see two cards and after reboot randomly pick eth0 us Intel or Realtek. How to force Unraid to use only pcie nic and do not use motherboard nic? I want to switch to intel beacuse realtek prevent higher C states.

Intel NIC is failing to initialize:

 

Apr 17 09:53:54 Tower kernel: igc 0000:02:00.0: Unable to change power state from D3cold to D0, device inaccessible

 

See if this helps:

Should I run "append pci=realloc=off initrd=/bzroot" in Unraid console?

[JorgeB]

No, you need to add it to the boot options in syslunix, click on the flash drive then scroll down to the syslinux section

 

Add pci=realloc=off like the highlighted option:

Ok I did like you said, after that I disable realtek in bios and remove network.cfg.

No I see Device eth0 does not exist and igc: probe of 0000:02:00:0 failed with error -13

If you didn't yet, try a different PCIe slot, if that doesn't help suggest trying a different NIC

My motherboard has only one pcie slot :(, I must live with Realtek and maximum C3 state
