5.3. Configure Linux kernel using SYSLINUX

Edit each LABEL entry to add an APPEND line containing the serial console parameter to pass to the Linux kernel. Like LILO, if a kernel already has parameters, then add our parameters to the list after APPEND.

For example:

APPEND console=tty0 console=ttyS0,9600n81

There are some traps for beginners in the differences between LILO and SYSLINUX. LILO uses append=, whereas SYSLINUX uses just append. lilo needs to be run after each change to /etc/lilo.conf, whereas syslinux does not need to be run after changing \SYSLINUX.CFG.
