Dell External OEMR 2850 User Manual page 88

This deployment method is the easiest to assemble, but is the least flexible.
Any change to the system configuration, for example, requires the creation of
a new bootable CD. This method does not provide a writable media making it
necessary to use predefined and tested configuration files.
Creating a Bootable CD
Bootable CDs can be created using any commonly available CD burning
software in a two-part process that requires a self-bootable ISO image with
drivers that load from system files. When you create a bootable CD, this
image is supplied to the CD burning software along with the complete
deployment directory structure, which includes all necessary supporting files
to perform the deployment. The CD burning software creates an image of the
self-bootable ISO image and the deployment files on the CD.
NOTE:
See "Running Deployment Scripts Using DTK and Embedded Linux" for more
information about creating an embedded Linux-bootable CD.
Using DTK Utilities and Scripts From a Bootable CD
The bootable CD can be configured to start and execute the master
deployment file during the booting process. The master deployment file
performs all necessary pre-operating system configuration tasks and then
installs the operating system from the files in the deployment directory
structure on the CD.
NOTE:
You must write the master deployment file. This file is not provided with the
sample scripts.
NOTE:
You must create a RAMDISK for temporary data storage when using a
bootable CD for a local deployment.
Creating a Customized Bootable CD
See "Running Deployment Scripts Using DTK and Embedded Linux" for
details on how to create a customized version of a single embedded Linux
image that can work across all Dell systems.
