Embedded Linux questions

Q: After installing Linux, I am not able to boot to the utility partition by pressing the <F10> key during

reboot.

A: Re-create the utility partition using the upinit.sh script and install grub in the boot partition.

Q: When booting DTK through PXE, my system displays error messages, unknown behavior, and also

leads to a kernel panic sometimes. However, booting from the media causes no problems.

A: 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.

Q: Can we use the same sample scripts that we have from earlier versions of DTK?

A: The scripts written for the previous versions of DTK do not work in the later versions for embedded

Linux. For the sample scripts, see the directory /opt/dell/toolkit/template/scripts .

Q: After the DTK deployment is complete, the Red Hat Enterprise Linux Server installation keeps going

into attended mode or halts with the message ks.cfg not found.

A: If the initrd.img is not available in the operating system, get the latest update of Red Hat Enterprise

Linux Server or prepare driver disks for your network or disk controller.

Q: How to apply driver disks during operating system installation?

A: You can apply driver disks as follows:

1. During operating system installation, after the first reboot, attach the driver-disk.iso file to the DVD-

ROM or virtual media.

2. At the grub prompt, press <a> followed by <dd> and, then press <Enter>.

Q: Why DTK ELI (32–bit) does not successfully boot up a Dell server running in UEFI mode?
