Hi, > Our algorithm is > failing to discover if this iso[1] is bootable.
I am curious to learn about the expectations of that algorithm. The ISO looks like being bootable via CHRP. >From my cheatsheet http://bazaar.launchpad.net/~libburnia-team/libisofs/scdbackup/view/head:/doc/boot_sectors.txt "CHRP is marked by an MBR partition entry of type 0x96 spanning the whole ISO 9660 image." I cannot spot "ppc64el" in http://cdimage.debian.org/mirror/cdimage/archive/latest-oldstable/powerpc/iso-cd/ Old-stable "powerpc" was made by genisoimage rather than xorriso. It has an Apple Partition Map additionally to the CHRP MBR, probably pointing to a HFS filesystem. So if your algorithm looks for magic number {'E','R'} at the start of the file, that would be what's missing in "ppc64el" ISOs. (Together with the HFS, of course.) -------------------------------------------------------------------- In case this does not yet explain the riddle: What was the most recent ISO which passed your tests ? Can you run GNU xorriso >= 1.3.8 on that ISO ? (Debian's xorriso is still at 1.3.2, i fear.) xorriso -indev ...iso \ -report_el_torito plain \ -report_system_area plain \ -pvd_info Have a nice day :) Thomas -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
