Install the patch as follows.

1. log on to the graphic interface using the super administrator root account, put the first CD of Red Hat Enterprise Linux 5 into the optical drive, click the Terminal menu in Applications → Accessories, and enter in the window:

# Mount/dev/cdrom/mnt

# Cd/mnt/Server

# Cp kernel-PAE-2.6.18-8.el5.i686.rpm/tmp.

# Cd/tmp

# Rpm-ivh kernel-PAE-2.6.18-8.el5.i686.rpm

# Umount/mnt

Note: l in el5 is not 1.

2. restart the system and remove the installation CD from the optical drive. After the restart, press any key on the Linux Startup interface and choose 2.6.18-8. el5PAE to enter the system.

3. Insert the floppy disk of the storage controller driver created during system installation into the soft drive, and then enter the following command:

# Mount/dev/sdb/mnt (sdb is the usb drive device number)

# Cd/mnt

# Cp modules. cgz/tmp

# Cd/tmp

# Gzip-dc modules. cgz | cpio-div

# Cd 2.6.18-8. el5PAE/i686

# Cp *. ko/lib/modules/2.6.188.el5PAE/updates/

# Cd/lib/modules/

# Depmod-av 2.6.18-8. el5PAE analyzes the dependencies of loaded modules.

# Mv/boot/initrd-2.6.18-8.el5PAE.img/boot/initrd-2.6.18-8.el5PAE.img.old

# Mkinitrd/boot/initrd-2.6.18-8.el5PAE.img 2.6.18-8. el5PAE
