LILO configuration

If you are using LILO, complete the following steps:

Complete the following steps to modify the /etc/lilo.conf file:

Add the following text to the end of the first default=linux line:

                        -Monitor

Comment out the map=/boot/map line by adding a # at the beginning of this line.
Comment out the message=/boot/message line by adding a # at the beginning of this line.

Add the following line before the first image=... line:

                        # This will allow you to only Monitor the OS boot via SOL

Add the following text to the end of the first label=linux line:

                        -Monitor

Add the following line to the first image=... section. This enables SOL.

                        append="console=ttyS1,19200n8 console=tty1"

Add the following lines between the two image=... sections:

                        # This will allow you to Interact with the OS boot via SOL
image=/boot/vmlinuz-2.4.9-e.12smp
    label=linux-Interact
    initrd=/boot/initrd-2.4.9-e.12smp.img
    read-only
    root=/dev/hda6
    append="console=tty1 console=ttyS1,19200n8 "

Type lilo and then press Enter to store and activate the LILO configuration.

When the Linux operating system starts, a LILO boot: prompt is displayed instead of the graphical user interface. Pressing Tab while at this prompt will install all of the boot options that are listed. To load the operating system in interactive mode, type linux-Interact and then press Enter.
