We just purchased several Dell Precision 7750 laptops with the intention of installing CentOS 7 on them. CentOS 7 seem to install on them fine. However, after booting up, I realized that neither the onboard NIC or the wifi device were recognized. When I did an ifconfig, the only interface listed was the loopback. It has an Intel I219-LM network device which should use the e1000 driver. I did some research and Dell says that the latest version of the Dell Precision laptops only support Linux operating systems of RHEL 8.2 and Ubuntu 20.04 LTS. We require CentOS 7 so I need to make this work if possible. I did an lshw and saw that several devices were "UNCLAIMED" which I found out means that a driver is not associated with the device. My initial thought is that CentOS 7 isn't recognizing the bus so in turn, it can't recognize the devices that are on that bus. These are the devices set as "UNCLAIMED".

If I could just get the Ethernet Adapter to work, I think I would be happy with that.

Re: CentOS 7 install on Dell Precision with Intel I9
You'd need to provide the output from lspci -nn | grep -i net to be sure but the ELRepo project have a kmod-e1000e package which supplies a newer version of the e1000e kernel module and that supports several newer Intel gigabit adapters. You'll also want to install their elrepo-release package that adds their yum repo to the system so that you get future updates to the kmod package as and when they are released.
The only other thing in your list of devices that perhaps you might need a driver for is the smart card device but that'll be more tricky.
Code: Select all
kmod-e1000e.x86_64 3.8.4-3.el7_9.elrepo elrepo
The future appears to be RHEL or Debian. I think I'm going Debian.

@jeffdm2005: That sounds similar to the problem I had with a Dell Precision 7550 several months ago. Refer to this thread:

I couldn't use the elrepo repo at my site, so I ended up downloading the driver from Intel's website, building the .rpm file, and running it.
