Does any DOS able to boot with Ventoy?

[Gannet]

Does anybody has any DOS to successfully boot with Ventoy for updating BIOS/UEFI/Firmware etc.?

I have FreeDos.ima but this type of image is only supported by Grub4DOS and not supported by Ventoy.

Would be appreciated if someone could provide with some working type of image with DOS/FreeDOS/PCDos etc.

Thanks.
