Mark a file bootable within a DEC Alpha ISO-9660 image

setcdboot' is used on the DEC Alpha platform to mark a file bootable within an Alpha ISO-9660 image bootable. First create an ISO-9660 image using mkisofs’, and then run

setcdboot <name_of_iso_image> <boot_path_within_image>

Once a bootable file image has been marked with `setcdboot’, burn the image to CDROM media in the usual manner. To boot the resulting CDROM, simply specify the CDROM device as the boot device and the Alpha will boot as if from hard disk.
