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.
