field), a menu, and prompt field for entering kernel parameters. For more details, see the

textmenu_chooser.txt documentation provided with the elilo source code.

After selection of one of the boot images, elilo uses tftp to retrieve the kernel image identified

in the image field and the initrd file identified in the initrd field, which is located relative

to the directory from which elilo was retrieved. The kernel is then started with any kernel

parameters specified in the append field of the elilo.conf configuration file or provided by

the user.

The elilo.efi, vmlinuz, and initrd files are copies of the boot loader, boot kernel, and

initial file system from the Linux distribution media. The boot loader, boot kernel, and initrd

image are stored in an ISO image on the Linux distribution media.

To extract these files perform the following steps:

1. Make the OS distribution media or ISO image available by choosing the appropriate method

from the following:

Using Physical Media: Load the OS distribution media into the DVD drive (or make

it available using vMedia).

b. Mount the OS distribution, enter:

# mount /media/dvdrom

c. Change directories to the loop-back directory, enter:

# cd /media/dvdrom/

Using an ISO Image: a. Loop-back mount the ISO image using the following

commands:

# mkdir /tmp/distroImage

# mount -o loop /path/to/ISO \

/tmp/distroImage

b. Change directories to the loop-back directory, enter:

# cd /tmp/distroImage

2. Create a directory to loop-back mount the boot image file from the distribution media then

mount it by entering the following commands:

# mkdir /tmp/loopmount

RHEL4U4: # mount -o loop images/boot.img /tmp/loopmount

SLES10: # mount -o loop boot/ia64/image /tmp/loopmount

# mount -o loop boot.img /tmp/loopmount

3. From the loop-back mounted boot image, copy the boot loader, boot loader configuration

file (if desired), boot image, and initrd image to the root directory of the TFTP server.

# cd /tmp/loopmount/efi/boot

# cp bootia64.efi /path/to/TFTP/root/elilo.efi

# cp elilo.conf /path/to/TFTP/root/

4. Copy the boot image and initrd image to the images/RHEL4u4|SLES10 directory relative

to the root directory of the TFTP server.

5. Unmount the loopmount directory with the following commands:

# cd

# umount /tmp/loopmount
