This tutorial will show you how to install Funtoo on a UEFI system. UEFI, also known as the [[Wikipedia:Unified Extensible Firmware Interface|Unified Extensible Firmware Interface]], is a new firmware interface that is used on some newer computers as a replacement for the traditional PC BIOS. It has an integrated boot loader, so setting up booting is different.

This tutorial is meant to be an "overlay" over the Regular Funtoo Installation. Follow the normal installation and only follow steps in this tutorial when dealing with partitioning and configuring the boot loader (GRUB). All steps are otherwise identical to the regular installation process.

== What Are We Doing? ==
+
== Introduction ==
 
+
This is the Debian kernel. It is roughly equal to a kernel shipped by Debian Linux in their releases. Ebuild now support the <code>binary</code> USE flag. The aim of this ebuild is to have support for near all possible hardware and users shouldn't really dig into configs, aka "install and forget". Daniel has added a special config-extract command which can be used to list all available official Debian kernel configurations, and generate them from the Debian files included with the kernel.  
This guide will show you how to set up your UEFI system to load the GRUB boot loader, which will then load your Funtoo Linux kernel and initramfs. This is the "UEFI + GRUB" method as described on the [[Boot Methods]] page.
+
== Usage ==
 
+
== First Steps ==
+
 
+
To install Funtoo Linux on a UEFI system, first you need to boot SysRescueCD in UEFI mode. To do this, enable UEFI in your BIOS, and if necessary disable legacy booting. After some fiddling, you should be able to boot SysRescueCD and get a black and white text menu instead of the traditional aqua/cyan-colored menu. The black and white menu indicates that you booted SysRescueCD in UEFI mode. Once you've accomplished this, you're ready to continue with your Funtoo Linux installation and partition your drive. See below for details.
+
 
+
{{fancynote|If the <tt>/sys/firmware/efi</tt> directory exists, then you have successfully booted in EFI mode and will be able to configure your Funtoo system to boot in EFI mode. If the directory doesn't exist, fix this first. It is a requirement for setting up EFI booting.}}
+
 
+
== Partitioning ==
+
 
+
To set up your partitions for UEFI booting, you will create a ~500MB FAT32 partition on <tt>/dev/sda1</tt>, and set it to type <tt>EF00</tt> using <tt>gdisk</tt>.
+
 
+
 
<console>
 
<console>
Command: ##i##n ↵
+
###i## echo "sys-kernel/debian-sources binary" >> /etc/portage/package.use
Partition Number: ##i##1 ↵
+
###i## emerge debian-sources
First sector: ##i##
+
###i## nano -w /etc/boot.conf
Last sector: ##i##+500M ↵
+
###i## boot-update
Hex Code: ##i##EF00
+
 
</console>
 
</console>
 
+
{{fancyimportant|1=
This partition will serve as your Funtoo <tt>/boot</tt> filesystem as well as the partition that the UEFI firmware can read to load GRUB. Then you will set up swap on <tt>/dev/sda2</tt> and your root filesystem on <tt>/dev/sda3</tt>. To create the FAT32 filesystem, type:
+
<code>debian-sources</code> with <code>binary</code> USE flag also automatically installing a /usr/src/linux symlink pointing to debian kernel.}}
 
+
== Advanced use ==
<console>
+
Additional information about using <code>config-extract</code> tool and genkernel tips can be found here:
# ##i##mkfs.vfat -F 32 /dev/sda1
+
http://www.funtoo.org/Funtoo_Linux_Kernels#Using_Debian-Sources_with_Genkernel
</console>
+
{{EbuildFooter}}
 
+
Your <tt>/etc/fstab</tt> entry for this filesystem will also differ, and will look like this:
+
 
+
<pre>
+
/dev/sda1 /boot vfat noatime 1 2
+
</pre>
+
 
+
== Kernel ==
+
 
+
=== VFAT ===
+
 
+
Make sure you add VFAT support to your kernel if you are building it manually.
+
 
+
=== EFI Framebuffer ===
+
 
+
If you have the following option enabled in your kernel, then uvesafb and efifb will not be able to detect the framebuffer:
+
 
+
{{kernelop|title=Bus options (PCI etc.)|desc=
+
    [*] Mark VGA/VBE/EFI FB as generic system framebuffer (NEW)
+
}}
+
 
+
If you have that option enabled, ''you must also enable'':
+
 
+
{{kernelop|title=Device Drivers,Graphics support,Frame buffer Devices|desc=
+
    [*]  Simple framebuffer support
+
}}
+
 
+
This is the preferred method of using the EFI framebuffer, the efifb and uvesafb drivers will be used as a fallback if the above is not compatible.
+
== Known Issues ==
+
*With pure UEFI boot mode, with legacy mode disabled, following error expected:
+
** video driver not supported, boot hangs, hard reboot required.
+
*Choose UEFI first, next legacy driver. It depends on motherboard vendor and efi bios version.
+
**In UEFI bios choose grub option, if your succeeded with above guide, additional menu should appear in Boot Menu, otherwise it boots into EFI shell: <code>grub:NAME of you hard drive</code>
+
* On some systems, installing the packages that are required for UEFI booting with any gcc later than a 4.x.x release may lead to a black screen after the GRUB screen. To fix this, before you begin installing any packages on your system, emerge =gcc-4.6.4-r2 and proceed with the installation as usual. Remember to switch your compiler back to the version of gcc that came with your system after you have finished installing. To do this, use <code>gcc-config 2</code>.
+
 
+
=== Done! ===
+
 
+
Remember to follow all other steps in the regular Funtoo Install Guide. Assuming you did everything correctly, your system should now boot via UEFI! We will be adding UEFI support to boot-update soon to make this process easier.

Introduction

This is the Debian kernel. It is roughly equal to a kernel shipped by Debian Linux in their releases. Ebuild now support the binary USE flag. The aim of this ebuild is to have support for near all possible hardware and users shouldn't really dig into configs, aka "install and forget". Daniel has added a special config-extract command which can be used to list all available official Debian kernel configurations, and generate them from the Debian files included with the kernel.

Usage

# echo "sys-kernel/debian-sources binary" >> /etc/portage/package.use
# emerge debian-sources
# nano -w /etc/boot.conf
# boot-update
Important

debian-sources with binary USE flag also automatically installing a /usr/src/linux symlink pointing to debian kernel.
