You can place any compressed Linux kernel on this disk, and it should boot. To do so: Configure the kernel with the following facilities linked in: initrd, ramdisk, loop, msdos, fat, elf, ext2fs, procfs. Make your kernel with "make bzImage". Copy it to "linux" on the boot disk. Change directory to the boot disk and run ./rdev.sh to configure the kernel. Optionally, edit syslinux.cfg to add arguments to the "DEFAULT" line, or add an "APPEND" line with arguments to be appended to any user-typed command line as well as the default. Documentation to read: /usr/share/doc/syslinux/syslinux.doc.gz "man rdev" /usr/src/linux/Documentation/ramdisk.txt Source code: The scripts that create this disk and the other Debian bootstrap disks are installed in /usr/src/boot-floppies/ by the boot-floppies package. - Bruce Perens, 12-March-1996
