90 Serial Port Console Redirection

Edit the file /etc/grub.conf, as follows. See the sample file that follows, which shows the changes

described in this procedure.

Add the following two new lines in the

general settings

section of the file:

serial --unit=0 --speed=19200

terminal --timeout=10 serial

Append two options to the kernel line:

kernel ............. console=ttyS0,19200

If the

/etc/grub.conf

contains a

splashimage

directive, you must comment it out.

Table D-1. Sample File: /etc/grub.con

# grub.conf generated by anaconda

Note that you do not have to rerun grub after making changes to this file

# NOTICE: You do not have a /boot partition. This means that

# all kernel and initrd paths are relative to /, e.g.

# root (hd0,0)

# kernel /boot/vmlinuz-version ro root=/dev/sdal

# initrd /boot/initrd-version.img

#boot=/dev/sda

default=0

timeout=10

#splashimage=(hd0,2)/grub/splash.xpm.gz
