<!--T:214-->
Next, edit {{c|/etc/boot.conf}} using {{c|nano}} and specify "{{c|Funtoo Linux genkernel}}" as the {{c|default}} setting at the top of the file, replacing {{c|"Funtoo Linux"}}.
== == NVIDIA Graphics Card Users ==== <!--T:219--> <!--T:220-->If you have NVIDIA graphics and plan to set up a graphical environment, you have a couple of choices when it comes to graphics drivers -- the proprietary NVIDIA drivers provided by NVIDIA corporation itself, or the Open Source Nouveau drivers. If you don't know which to choose, we recommend starting with the proprietary NVIDIA drivers first for optimal performance on a wider range of hardware. <!--T:221-->;If using proprietary NVIDIA graphics...: It is safe to leave the {{c|nomodeset}} parameter in {{c|/etc/boot.conf Configuration ==}} as the proprietary drivers handle setting the graphics mode themselves. However, you will need to ''blacklist the nouveau modules'' so they do not load upon boot. See [[Package:NVIDIA_Linux_Display_Drivers|the NVIDIA Linux Display Drivers page]] for information on how to get these drivers set up.
Most users, particularly those who plan on setting up a graphical environment, will want to eventually remove {{c|nomodeset}} from {{c|params}} in {{f|/etc/make<!--T:222-->;If using Nouveau..conf}}. : {{c|nomodeset}} prevents should be ''should be removed'' as explained in the kernel from changing graphics modes at boot. This option is in {{c|/etc/boot'''Other Graphics Cards''' section below.conf}} by default for a couple of good reasons:
* For users with HiDPI (4K+) displays==== Other Graphics Cards ==== <!--T: when the kernel automatically changes graphics modes, the console font will be tiny and unreadable.* For users with incompatible graphics cards: Some graphics cards don't handle mode setting properly and this can result in a blank screen after reboot. 223-->
Disabling mode <!--T:224-->Most users, particularly those who plan on setting is therefore up a goodgraphical environment, safe will want to eventually remove {{c|nomodeset}} from {{c|params}} in {{f|/etc/make.conf}}. {{c|nomodeset}} prevents the kernel from changing graphics modes at boot. This option is in {{c|/etc/boot.conf}} by default for initial installs a couple of Funtoo Linux. good reasons:
However<!--T:225-->* '''For users with HiDPI (4K+) displays''': when the kernel automatically changes graphics modes, the console font can be tiny and unreadable.* '''For users with incompatible graphics cards''': Some graphics cards don't handle mode setting properly and this can result in a blank screen after reboot.  <!--T:226-->Disabling mode setting is therefore a good, safe option for initial installs of Funtoo Linux, but most users will ''want to remove this option.'' <!--T:227-->This is because essentially all graphics drivers (the big exception being the proprietary NVIDIA drivers) ''require'' rely on mode setting to be enabledset the graphics mode of your display. So while most users ''will need to remove it'', and run {{c|nomodesetego boot update}} is a good option to get the initial system up and running, most users are encouraged to remove it reboot before they set up X or Wayland.Otherwise, X will not be able to initialize the display. Of course, you can also choose to remove it now and then you won't need to remember to remove it later :)
{{Important|Make a mental note -- while {{c|nomodeset}} is a safe option for now, most users will want to ''remove'' the {{c|nomodeset}} option from {{c|params}} prior to setting up their graphical environment! But it's generally OK to keep it enabled until Funtoo Linux is fully installed and you have performed your inital reboot into your new system.}}
<!--T:199-->
{{c|/etc/boot.conf}} should now look like this:
}
<!--T:228-->
"Funtoo Linux" {
kernel bzImage[-v]
}
<!--T:229-->
"Funtoo Linux genkernel" {
kernel kernel[-v]
initrd initramfs[-v]
  <!--T:230--># IMPORTANT: Most users -- remember to REMOVE nomodeset below!  <!--T:231-->params += real_root=auto rootfstype=auto nomodeset
}
}}
If you are booting a custom or non-default kernel, please read {{c|man boot.conf}} for information on the various options available to you.
=== Intel Microcode ===<!--T:232-->
<!--T:233-->
{{c|ego boot}} will ensure that you have the most recent Intel CPU microcode installed on your system if you emerge the
following packages:
<!--T:234-->
{{console|body=
%chroot% ##i##emerge intel-microcode iucode_tool
}}
<!--T:235-->
This is not necessary for AMD systems.
<!--T:213-->
You only need to run <code>{{c|grub-install</code> }} when you first install Funtoo Linux, but you need to re-run <code>{{c|ego boot update</code> }} every time you modify your <code>{{c|/etc/boot.conf</code> }} file or add new kernels to your system. This will regenerate {{c|/boot/grub/grub.cfg}} so that you will have new kernels available in your GRUB boot menu, the upon your next time you reboot.
