5. Copy the file /tmp/initrd_update.img into the directory the holds the target that you want
to use for installation. This directory is placed under the /tftpboot/pxelinux/ directory.
For example, /tftpboot/pxelinux/r5su3/ might hold the PXE target for Red Hat
Enterprise Linux 5.3 Server.
6. Edit the /tftpboot/pxelinux/pxelinux.cfg/default file to include an entry that
includes the initial RAM disk update that you just created, in the following format:
label target-dd
kernel target/vmlinuz

In this example, driver_update.iso is a driver update image file that you downloaded from the
Internet to a directory on your PXE server. The target that you want to PXE boot from is located in
/tftpboot/pxelinux/r5su3
At the command line, change to the directory that holds the file and enter the following commands:
$ cp driver_update.iso /tmp/initrd_update/dd.img
$ cd /tmp/initrd_update
$ find . | cpio --quiet -c -o | gzip -9 >/tmp/initrd_update.img
$ cp /tmp/initrd_update.img /tftpboot/pxelinux/r5su3/dd.img
Edit the /tftpboot/pxelinux/pxelinux.cfg/default file and include the following entry:
label r5su3-dd
kernel r5su3/vmlinuz
append initrd=r5su3/initrd.img,r5su3/dd.img
