This bootloader has no bells or whistles, it is simply a prototype with the minimum amount of smarts required to load a linux kernel (though loaders for other formats could be added). Currently it only supports booting x86-64 bzImages but i386 support is planned for release 0.9, with a 1.0 release coming after a thorough round of testing. If anyone has the time and inclination I'd really appreciate it if they could have a play with it on their machines and report any bugs. Testing has mainly been done under qemu up to this point so there are bound to be some lurking bugs that only show up on real hardware. As there is no configuration file parser all config is done via command-line arguments. To boot a kernel simply type, Shell> efilinux -l efilinux loader 0.8 Devices: 0. "Acpi(PNP0A03,0)/Pci(1|1)/Ata(Primary,Master)" Shell> efilinux -f Acpi(PNP0A03,0)/Pci(1|1)/Ata(Primary,Master):\bzimage efilinux understands the LILO-style initrd= kernel command-line argument, but the full device path to the initrd is required. A kernel command-line can be passed at the end of the command-line, e.g. Shell> efilinux -f bzimage console=ttyS0 root=/dev/sdb The latest release is available at, git://git.kernel.org/pub/scm/boot/efilinux/efilinux.git This project is a preview of the EFI stub patches that I hope to push into the kernel. The EFI stub will allow a bzImage to masquerade as an EFI application, such that the firmware will load the bzImage and jump to its entry point without requiring a bootloader at all. -- Matt Fleming, Intel Open Source Technology Center
