1 | General note on [U]EFI x86_64 support | ||
2 | ------------------------------------- | ||
3 | |||
4 | The nomenclature EFI and UEFI are used interchangeably in this document. | ||
5 | |||
6 | Although the tools below are _not_ needed for building the kernel, | ||
7 | the needed bootloader support and associated tools for x86_64 platforms | ||
8 | with EFI firmware and specifications are listed below. | ||
9 | |||
10 | 1. UEFI specification: http://www.uefi.org | ||
11 | |||
12 | 2. Booting Linux kernel on UEFI x86_64 platform requires bootloader | ||
13 | support. Elilo with x86_64 support can be used. | ||
14 | |||
15 | 3. x86_64 platform with EFI/UEFI firmware. | ||
16 | |||
17 | Mechanics: | ||
18 | --------- | ||
19 | - Build the kernel with the following configuration. | ||
20 | CONFIG_FB_EFI=y | ||
21 | CONFIG_FRAMEBUFFER_CONSOLE=y | ||
22 | - Create a VFAT partition on the disk | ||
23 | - Copy the following to the VFAT partition: | ||
24 | elilo bootloader with x86_64 support, elilo configuration file, | ||
25 | kernel image built in first step and corresponding | ||
26 | initrd. Instructions on building elilo and its dependencies | ||
27 | can be found in the elilo sourceforge project. | ||
28 | - Boot to EFI shell and invoke elilo choosing the kernel image built | ||
29 | in first step. | ||
