Welcome to the Slackware Linux custom LILO bootdisk!  

By default, this disk boots a root Linux partition on $ROOT_DEVICE when
you hit ENTER.  If you'd like to boot some other partition, use a command
like this on the LILO prompt below:

    mount root=/dev/sda1 ro

Where "/dev/sda1" is the partition you want to boot, and "ro" specifies that
the partition should be initially mounted as read-only.  If you which to mount
the partition read-write, use "rw" instead.  You may also add any other kernel
parameters you might need depending on your hardware, and which drivers are
included in your kernel.
