| This is a tool for building a simple TFTP boot loader which embodies |
| several kernel images for different Sun architectures and a ramdisk root |
| image. To minimize memory usage, the images are gzipped. After starting |
| the boot loader, the architecture is detected, the appropriate kernel is |
| unpacked and then the booting procedure is launched. |
| |
| How to build the boot image: |
| |
| 1. Prepare a kernel image for each supported architecture (in the ELF |
| format, uncompressed). Currently TILO expects atleast one sun4u or |
| sun4cdm kernel. You can only supply one of each kind. It will be |
| possible to add Sun4 support in the future as well. |
| |
| 2. Prepare a root image for the initial ramdisk. It can be compressed, or |
| raw. Tilo will compress it if needed. |
| |
| 3. Run the "tilo" script with the following parameters: |
| |
| tilo [ -o output ] <kernel images> <root image> |
| |
| A boot image will be created which contains everything necessary to boot on |
| each architecture. |
