Add support for building an hybrid ISO9660 image compatible with legacy and UEFI BIOS. Note that this is not about an (iso)hybrid image, which can boot from both a CDROM or a USB stick, but really about an image being bootable from the legay BIOS or EFI; the two are orthognal. The option -eltorito-alt-boot need to be used in the xorriso command to generate the hybrid image. That option is a separator, meaning the previous boot entry is done, and the following boot options define a new boot entry. The -no-emul-boot defines the type of the current boot image; that's why it has to now be repeated in each of the BIOS and EFI options. Finally, for symetry and consistency between the BIOS and EFI options, we move the BIOS image option first. Note: the BIOS boot image options have to be provided before the EFI ones, or the system won't boot; the underlying reason is not known...

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
