Bootdisk Target
From RockWiki
About
The bootdisk target offers a small, bootable Linux system suitable for installation and rescue purposes. It is often used to make ISO images of other targets - like Crystal ROCK - bootable.
This system uses a two-staged boot-up: the first stage contains a minimal system and is loaded as an initial ramdisk by the boot-loader. The second stage can be loaded to another ramdisk from an arbitrary device (usually a CD/DVD). Since the second stage is completely loaded to RAM thesis writing service, the device it is loaded from can be removed (e.g. to change install CDs).
The bootdisk build process also creates a set of bootable floppy images, containing a Linux kernel and the first stage initial ramdisk.
Furthermore an especially small second stage is provided for systems with less than 64 MB of RAM.
