Libreboot has ISOLINUX and grub2 support. Neither work with the Devuan Daedalus ISOs. I did not copy the ISO onto the drive like in a file manager. I properly burned it onto the usb using the `dd` command to the /dev/sdb aka usb device, like I do with linux mint, artix, and devuan chimaera, and I'm able to boot from the usbs with all those distros except devuan daedalus. I don't use ventoy.

The burned devuan daedalus ISO is mountable, I can mount the usb and go through the files. I'm not sure why libreboot doesnt find anything.

Devuan Chimaera booted from isolinux in libreboot only loads the devuan background image. Booting from grub2 shows the grub menu.

Devuan Daedalus does the same thing with isolinux. It doesn't work at all with grub2. So it ends up being unbootable.

Linux Mint works with isolinux and grub2. And Arch Linux works with isolinux. I found this libreboot article that says libreboot didnt directly scan for syslinux configs until recently.
