Your ISO image is ready for booting.

Media-based deployment

The different media-based deployments are as follows:

• Deployment Using Custom Scripts

• Deployment Using RPMs

• Deployment Using USB

Deployment using custom scripts

1. Obtain the ISO image of the embedded Linux at www.dell.com/support.

2. Extract the contents of the ISO image to a folder (for example, isoimage) on your hard drive.

3. Copy the custom scripts into the same folder.

NOTE: Your scripts must also take care of copying miscellaneous items to unlock the media, so

that the media can be mounted and ejected as per the operating system’s installation process.

4. In /mnt/cdrom/isolinux/isolinux.cfg (for BIOS mode) or in /mnt/cdrom/EFI/BOOT/dtk_grub.cfg (for

UEFI mode), edit the cd install section to point to your customized start-up script. In other words,

add the

share_script option and then use mkisofs to create the ISO image as follows:

mkisofs -o output.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-

emul-boot -boot-load-size 4 -boot-info-table -pad -r -J -hide-joliet-trans-

tbl -eltorito-alt-boot -e efiboot.img -no-emul-boot isoimage

NOTE: It is important to use mkisofs to make your customized image because the ISO Linux

recognizes only the isolinux.cfg (and all files within /isolinux). If you do not use mkisofs, the

HAPI libraries of the DTK cannot load and most of the Dell Update Packages do not work.

NOTE: The scripts that you copy into the media are copied to the RAM disk and run from the

RAM disk. This task is done to make sure that the media is not locked. Ensure that your sample

scripts have valid path names.

5. Burn the ISO contents to a media.

6. Your ISO image is ready for booting.

Using RPMs

You can install DTK using Red Hat Package Manger (RPM), Yellowdog Updater, Modified (YUM) or any

other RPM Installation Manager, or using DTK tools.

Installing DTK RPMs using RPM

To install DTK RPMs using RPM:

1. Mount the DTK media at /mnt/cdrom.

2. Navigate to the /mnt/cdrom/RPMs directory.

NOTE: The /mnt/cdrom/RPMs directory contains all DTK RPMs and the dependency RPMs.

3. Install the required DTK RPMs.

NOTE: To resolve the RPM dependency related issues, install the missing RPMs from /mnt/

cdrom/RPMs directory. If the RPMs are not available in this directory, install these RPMs from

the operating system media.
