| 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. |
