=== Modern Intel Chipsets ===
If you have a modern Intel system (Skylake, Coffee Lake or newer) then you may be better served by the newer {{c|debian-sources}} kernel
as it will have support for more modern Intel WiFi and integrated graphics chipsets. To use this kernel, you will want to perform the following steps:
{{console|body=
%chroot% ##i##echo "sys-kernel/debian-sources binary" > /etc/portage/package.use
%chroot% ##i##emerge -av debian-sources
}}
Then, when you configure {{c|/etc/boot.conf}} in the next section, you will want to ensure that {{c|debian-sources}} (not {{c|debian-sources-lts}}) is selected as your default kernel.

{{Note|NVIDIA card users: the <code>binary</code> USE flag installs the Nouveau drivers which cannot be loaded at the same time as the proprietary drivers, and cannot be unloaded at runtime because of KMS. You need to blacklist it under <code>/etc/modprobe.d/</code>. If you're planning to use NVIDIA's drivers, see [[Package:NVIDIA_Linux_Display_Drivers|the NVIDIA Linux Display Drivers page]] for blacklisting information.}}

Firmware

At this point it is wise to emerge the latest sys-kernel/linux-firmware package, because various drivers rely on firmware blobs and instructions. Hardware like Wi-Fi cards, graphic cards, network cards, and others will not work properly or at all if firmware is not available. If using the stage3 image, perform the following to install it. linux-firmware will be already installed if using the gnome image:

chroot # emerge -av linux-firmware
