Running Deployment Scripts and RPMs Using DTK and Embedded Linux 131
6 The isolinux.cfg file is ready for PXE-booting. Copy this isolinux.cfg file
into the PXE configuration folder.
7 Create your own start-up script and place it in the network share specified
in your modified
isolinux.cfg file.
8 The modified script is picked up and executed during the boot process.
NOTE: The network share on which you have the scripts and DTK files are mounted
to /opt/dell/toolkit/systems.
NOTE: Ensure that you specify the correct RAMDISK size in the pxe config file
before booting through PXE. (A sample pxe config file is provided in
/mnt/cdrom/isolinux/isolinux.cfg.)
Media-Based Deployment
There are two ways:
•Using Scripts
•Using RPMs
For script-based deployment:
1
Obtain the ISO image of the embedded Linux available at
support.dell.com .
2 Burn the ISO image using any commonly available CD/DVD burning
software.
NOTE: When you create a bootable CD/DVD, this image is supplied to the
CD/DVD burning software along with the complete deployment directory
structure, which includes all necessary supporting files to perform
the deployment.
The CD/DVD burning software creates an image of the self-bootable ISO
image and the deployment files on the CD/DVD.
3 Extract the contents of the ISO image to a folder on your hard drive.
4 Copy your custom scripts into the folder you created in step 3. (For an
example of the folder structure, see "Installation for Embedded Linux" on
page 89.)
NOTE: Your scripts should also take care of copying miscellaneous items to
unlock the media, so that the media can be mounted and ejected as required
by the operating system’s installation process.
