The other booting option that comes with Slackware Linux is LOADLIN.
LOADLIN is a DOS executable that can be used to start Linux from a running
DOS system. It requires the Linux kernel to be on the DOS partition so
that LOADLIN can load it and properly boot the system.
During the installation process, LOADLIN will be copied to root's home
directory as a .ZIP file. There is no automatic setup process for LOADLIN.
You will need to copy the Linux kernel (/vmlinuz) and
the LOADLIN file from root's home directory to the DOS partition.
LOADLIN is useful if you would like to make a boot menu on your DOS
partition. A menu could be added to your AUTOEXEC.BAT
file that would allow you to pick between Linux or DOS. A choice of Linux
would run LOADLIN, thus booting your Slackware system. This
AUTOEXEC.BAT file under Windows 95 will provide a
sufficient boot menu:
You will want to specify your root partition as a Linux device name, like
/dev/hda2 or something else. You can always use
LOADLIN at the command line. You simply use it in the same manner as it
is in the example above. The LOADLIN documentation comes with many examples
on how to use it.
