Chapter 3. Operating system configuration

This section provides instructions for configuring your operating system for SOL
operation, including any required installation of device drivers. It includes the
following instructions:

Linux configuration

Complete one of the following procedures to enable SOL sessions for your Linux
operating system. You must be logged in as a root user to perform these
procedures. For SOL operation, you must also configure the Linux operating
system to expose the Linux initialization (booting) process. This enables users to
log in to the Linux console using an SOL session and directs Linux output to the
serial console. See the documentation for your specific Linux operating-system type
for information and instructions.
Note: You do not have to configure the Linux operating system when using a
BladeCenter JS20 Type 8842 blade server; however, you still must install the
Ethernet controller device drivers (see "Installing the Ethernet controller device
driver for Linux operating systems" on page 21).

Red Hat Enterprise Linux ES 2.1 configuration

Note: This procedure is based on a default installation of Red Hat Enterprise
Linux ES 2.1. The file names, structures, and commands might be different for
other versions of Red Hat Linux.
Complete the following steps to configure the general Linux parameters for SOL
operation when using the Red Hat Enterprise Linux ES 2.1 operating system.
Note: Hardware flow control prevents character loss during communication over a
serial connection. You must enable it when using a Linux operating system.
1. Add the following line to the end of the # Run gettys in standard runlevels
2. Add the following line at the bottom of the /etc/securetty file to enable a user
