Some OSCDIMG reference for "dual" (BIOS/UEFI) boot:
Hmm wouldn't that just involve including a BOOTX64.efi file in /efi/boot/? If I am not mistaken, the
BIOSEFI boot up utility would then detect the file presense and should give you an option to boot it if EFI is enabled or if you have a cool setup it would give you dual boot options meaning you can either boot in EFI or standard mode. The config file would still need to be manually edited. I think you can do this right now even with the old version of Multiboot ISO Maker. You just build the ISO folder structure and you build the ISO.
And evidence of more "strange" formats:
So, NO, the topic is far from being "simple" and there are still lots of not fully explored aspects of this...
Well, you write it, and then people will either like it or not, of course there is interest in it , but we want to see the actual bytes , not a "declaration of intent"!
Either way, if I was to update this utility, it would have to be a complete re-write. The code is too old and it can be re-written in much better way. If people show interest, I would definitely consider it.
I used one today.
P.S. I don't remember when was the last time I used a CD bootable. I have a UFD with a number of different partitions on it, each having a different Linux live distro or some sort of ISO (Macrium Reflect, Parted Magic etc..) - much more convenient
(and faster) than a DVD / CD etc.
