Does anyone know if a device like this exists:
I'm looking for an USB memory stick or hard disk that can emulate a
CDROM/DVD drive. I should be able to somehow copy an ISO file to it, and
that ISO file should then be visible as a physical CDROM drive.
I'm not looking for software CDROM emulators. I'm already using Daemon
tools for that. What I need is a quick way to emulate a CDROM from which I
can boot for installation or firmware upgrade purposes without having to
burn a CD each time I need one.
