As long as it is not about the old Macs which the APM of Fedora and some Gentoo ISOs wants to make boot, and not about ISOs made with isohybrid options --partok -ctrlhd0 --forcehd0. > which would be the step-by-step instructions for users of other > isohybrid images? Copy at most 432 bytes to the start of USB stick or ISO image file: iso=/dev/sdc or iso=image.iso dd conv=notrunc if=isohdpfx.bin.170324 bs=1 count=432 of="$iso" > W...

...h or -s we get to the same undecidable discussions about cylinder size which we had a while ago. We did not really make progress with getting this well documented. -e , -t, -i are MBR specific. -o is a bit questionable, as a non-zero value will normally make the partition unmountable. --forcehd0, --ctrlhd0, --partok choose the built-in MBR template.

Hi, Ady wrote: > so, why the original isohybrid image from Debian and many other > isohybrid images have mostly (but not all) "00s" in place of the "90s"? That's a fake Block0 of an Apple Partition Map. Part of mjg's layout. Caused by isohybrid option --mac or xorrisofs option -isohybrid-apm-hfsplus. * Fedora has it with EFI FAT filesystem in one partition

My interpretation of Didier's questions is less depth and more user-friendly practical commands for end-users. Our points of view
