# 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

4. To enable multiple GRUB options to start Virtual Console sessions through the RAC serial connection, add the following line to
all options:
console=ttyS1,115200n8r console=tty1
The example shows console=ttyS1,57600 added to the first option.
NOTE: If the boot loader or operating system provides serial redirection such as GRUB or Linux, then the BIOS
Redirection After Boot setting must be disabled. This is to avoid potential race condition of multiple components
accessing the serial port.
Enabling login to the virtual console after boot
In the file /etc/inittab, add a new line to configure agetty on the COM2 serial port:
co:2345:respawn:/sbin/agetty -h -L 57600 ttyS1 ansi
The following example shows a sample file with the new line.
#inittab This file describes how the INIT process should set up
#the system in a certain run-level.
#Author:Miquel van Smoorenburg
#Modified for RHS Linux by Marc Ewing and Donnie Barnes
#Default runlevel. The runlevels used by RHS are:
#0 - halt (Do NOT set initdefault to this)
#1 - Single user mode
#2 - Multiuser, without NFS (The same as 3, if you do not have #networking)
#3 - Full multiuser mode
#4 - unused
#5 - X11
#6 - reboot (Do NOT set initdefault to this)
