5.1. Configure Linux kernel using LILO
For each image entry in /etc/lilo.conf add the line:
Figure 5-4. Recommended kernel parameters, LILO configuration
append="console=tty0 console=ttyS0,9600n8" |
Sometimes the append line will already exist. For example
In this case, the existing append line is modified to pass all the parameters. The result is:
As a complete example, a typical /etc/lilo.conf configuration from Red Hat Linux 7.1 is:
Example 5-1. Complete LILO configuration, as installed by vendor
boot=/dev/hda map=/boot/map install=/boot/boot.b prompt timeout=50 message=/boot/message default=linux image=/boot/vmlinuz-2.4.2-2 label=linux read-only root=/dev/hda6 initrd=/boot/initrd-2.4.2-2.img |
This is modified to
Example 5-2. Complete LILO configuration, modified for serial console
boot=/dev/hda map=/boot/map install=/boot/boot.b prompt default=linux # Changes for serial console on COM1: in global section # Deleted: message=/boot/message timeout=200 serial=0,9600n8 timeout=100 restricted password=de7mGPe3i8 image=/boot/vmlinuz-2.4.2-2 label=linux read-only root=/dev/hda6 initrd=/boot/initrd-2.4.2-2.img # Changes for serial console on COM1: in each image section append="console=tty0 console=ttyS0,9600n81" |
Now that we have finished configuring LILO, use the lilo command to install the new boot record onto the disk:
