I suspect Yggdrasil came before the QNX floppy, at least the one I played with at the time (http://toastytech.com/guis/qnxdemo.html http://toastytech.com/guis/qnxdemo.html). Even if I'm wrong there have probably been earlier Linux boot floppy disks (e.g.tomsrtbt, mulinux - which was great!). Somewhat related, at some point even SCO made a demo boot floppy for SCO Unix (or perhaps Openserver), it's still available on ftp.sco.com somewhere. No X and very few useful utilities in there.
