jaclaz Posted April 17, 2023 Share Posted April 17, 2023 Yep, but we need also (at least) one that works without copying to (maybe) spot some differences. I quickly checked only the first (Freedos Live) and the last (Aros Live). The first one is made with (good ol') mkisofs, the latter with genisoimage. Both are NOT hybrid images (i.e. first 16 sectors are 00's). Both are bootable (BootId 88) and bootmedia 0 (no emulation boot). First one has no joliet (but Rockridge), second one has both Joliet and Rockridge (and additionally uses ISO 9660:1999 Relaxed Format). One of the good things about mkisofs (that later programs stupidly removed) is the default feature of writing in the image the actual command line used to build the .iso, so the FreeDos iso has been made with the (rather "normal") commands: Quote MKI Sun Feb 20 07:45:28 2022 3.02a09 -quiet -o ../fd-hydra.iso -V FD13-LiveCD -r -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table jaclaz Link to comment Share on other sites More sharing options...
awkduck Posted April 17, 2023 Author Share Posted April 17, 2023 (edited) I noticed "Joliet UCS Level-1" on working ISOs. No Rock Ridge . I'll look into creating something. Edited April 17, 2023 by awkduck Link to comment Share on other sites More sharing options...
awkduck Posted April 17, 2023 Author Share Posted April 17, 2023 genisoimage -J -ucs-level 1 -o test.iso /iso_files This ISO failed to function. Link to comment Share on other sites More sharing options...
awkduck Posted April 19, 2023 Author Share Posted April 19, 2023 One of the CD ISOs, that works, was made with WinOnCD. Still UCS Level 1 and no Rock Ridge. Link to comment Share on other sites More sharing options...
jaclaz Posted April 20, 2023 Share Posted April 20, 2023 Yep, but the aros .iso is ucs level 3 (default), and (from what I know) the ucs level is only within the Joliet supplemental description, shouldn't affect mounting, only (maybe) listing of files/directories: http://littlesvr.ca/isomaster/resources/JolietSpecification.html#recording jaclaz Link to comment Share on other sites More sharing options...
SweetLow Posted May 1, 2023 Share Posted May 1, 2023 I checked ReactOS image - and all is working as expected without any errors: copy and mount of image (on USB NTFS drive, on ATA NTFS drive and on ATA FAT32 drive). Link to comment Share on other sites More sharing options...
