From A Linux Workstation; Create A Bootable Disk Image; Create A Cd Build Directory - HP Integrity rx1620 Deployment Manual

From a Linux workstation

The following sections show you how to create a bootable CD/DVD from a Linux system.

Create a bootable disk image

The SSTK includes the files you need to create a bootable disk image. Creating the disk image
involves copying these boot files to a small FAT partition and creating the image (.img) file.
The bootable disk image must be a FAT file system to be available at the EFI level. Also, if a
bootloader file named bootia64.efi is located in \efi\boot directory, the Integrity server
automatically executes that boot loader.
To create a bootable disk image:
1. Create a directory for the bootable image:
mkdir ./bootable-image
2. Use the dd command to create a blank file with the size needed to store the boot files:
dd if=/dev/zero of=./bootable-image/boot.img bs=1024 count=25000
3. Format this image file with FAT file system:
mkfs.msdos ./bootable-image/boot.img
4. Create a directory and mount this image file, for example:
mkdir ./bootable-image/image
mount ./bootable-image/boot.img ./bootable-image/image –o loop
5. Create the bootable directory (/efi/boot):
mkdir –p ./bootable-image/image/efi/boot
6. Copy the necessary files from boot_file/efi/boot to the
./bootable-image/image/efi/boot directory:
./bootable-image/image/efi/boot directory:
bootia64.efi
bootia64.conf
elilo.efi
elilo.conf (bootloader configuration file)
rootfs.gz (root file system)
linux (kernel)
7. If needed, copy additional files to ./bootable-image/image directory. These files might
include toolkit files, configuration files, or third-party tools.
8. Unmount the image file.
umount ./bootable-image/image
The boot.img file is now a FAT file system containing the bootia64.efi file, which boots
the Linux operating system.

Create a CD build directory

1. Create a directory:
mkdir ./linuxbootCD
2. Create a subdirectory to store the boot image:
mkdir ./linuxbootCD/boot
3. Copy the boot image file, boot.img, to the ./linuxbootCD/boot directory:
cp /bootable-image/boot.img ./linuxbootCD/boot
