CentOS 7 install on Dell Precision with Intel I9

Post by jeffdm2005 » 2021/04/20 19:59:56

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.

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the output from lspci -nn | grep -i net to be sure but the ELRepo project have a kmod-e1000e package which supplies a newer version of the e1000e kernel module and that supports several newer Intel gigabit adapters.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.

Code: Select all

kmod-e1000e.x86_64                            3.8.4-3.el7_9.elrepo                             elrepo
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.
CentOS 6 died in November 2020 - migrate to a new version!
