boot-floppies package contains all of the source code and
documentation for the installation floppies.
The rescue floppy has an Ext2 file system (or a FAT file system, depending on
your architecture), and you should be able to access it from anything else that
can mount Ext2 or FAT disks. The Linux kernel is in the file
linux.bin. The file
root.bin is a
gzip-compressed disk image of a 1.4MB Minix or Ext2 file system,
and will be loaded into the RAM disk and used as the root file system.
If you find it necessary to replace the kernel on the rescue floppy, you must configure your new kernel with these features linked in, not in loadable modules:
Be sure that the kernel you plan to use does NOT have CONFIG_DEVFS set. CONFIG_DEVFS is not compatible with the installer.
You'll also want to replace the
modules.tgz file on the driver
floppies. This file simply contains a
gzip-compressed tar file of
/lib/modules/kernel-version; make it from the root file
system so that all leading directories are in the tar file as well.
