Performing A Driver Update During Installation - Red Hat ENTREPRISE LINUX 5 Installation Manual

Chapter 7. Updating drivers during installation on Intel and AMD systems
3. Rename the driver update image file to dd.img.
4. At the command line, change into the /tmp/initrd_update directory, type the following
command, and press Enter:
find ­. ­| cpio ­­­quiet ­­c ­­o ­| gzip ­­9 >/tmp/initrd_update.img
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 target­dd
kernel target/vmlinuz
append initrd=target/initrd.img,target/dd.img
Where target is the target that you want to use for installation.
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 r5su3­dd
kernel r5su3/vmlinuz
append initrd=r5su3/initrd.img,r5su3/dd.img
