## How to Create the SIA Image and Prepare for PXE Boot

1. Preconfigure your network to support a Linux-based PXE server network installation.

   You may refer to the Linux distribution documentation for more information on configuring a PXE server.

2. In the PXE Linux directory, create a new subdirectory for the SIA image(s).

   On a Linux system, for example, the following command line creates a subdirectory for `suninstall` images:

   `# mkdir /home/pxeboot/suninstall`

3. Insert the SIA CD/DVD into a CD/DVD drive of a Linux-based PXE server and mount the CD/DVD.
4. Copy the `vmlinuz` (the bootable Linux kernel) and `initrd` (initial ram disk) files from the SIA CD/DVD to the `suninstall` subdirectory that you created.

   Use the correct path to the mounted CD image. This example uses `/mnt/cdrom`:

       # cp /mnt/cdrom/boot/isolinux/vmlinuz /home/pxeboot/suninstall
       # cp /mnt/cdrom/boot/isolinux/initrd.img /home/pxeboot/suninstall

5. Use an editor to add the following SIA references to the `pxelinux.cfg/default` file that is stored in the `/home/pxeboot` directory.

       default suninstall
       label suninstall
       kernel suninstall/vmlinuz
       append initrd=suninstall/initrd.img vga=0x314 ramdisk_size=900000 root=/dev/ram netboot

   Type the `append` command line from `append initrd=` to `netboot` as one continuous string with no returns.

6. Save the file, and then unmount and remove the SIA CD/DVD from the CD/DVD drive.

   You image is now ready to be booted from.
