Hey you lovely people out there,

Recently, I’ve got my 3 mini pc Beelink GTi12 Ultra delivered to my door, to use them as a cluster servers into my Homelab using Proxmox Hypervisor.

After completing post-installation of Proxmox everything went smoothly, issue started when I tried to configure the second 2.5G Lan NIC alongside the other but it didn’t show up under the Debian Linux environment! So I thought to myself I do other 2 mini pcs laying around already have Windows 11 pre-installed waiting to be configured and joined to the cluster, but when I open one of Windows 11 pro I shocked that there is only one Intel Ethernet I226V driver installed and showed up in any tool you may think of!

So it appears to me that no matter what OS I use, it seems that only 1 2.5G NIC work and other is just a piece past …

As usual, I went through official website and forums, trying to find any clue, one of bbs.bee-link threads suggested that no one needs to upgrade their BIOS unless problem arise, so I went and downloaded upgrade for my GTi12 201 BIOS driver from:
[https://dr.bee-link.cn/?dir=uploads%2FGTI%2FGTi12%2FBIOS]
(GTi12-BIOS-Version2-T201-Note-Original-Version) and followed the instructions, but I got to this stage where the device just freezes after I power it on and no screen or any sign of boot messages! only white led on power button.

By the way, I couldn’t find any entry for the Ethernet LAN NICs inside BIOS, only something called “Network Stack”

Any help please, they cost me Fortune to acquire.
