Thanks, Mogens. Something very mysterious is happening. I get

Eltorito validation header:
    Hid 1
    Arch 0 (x86)
    ID ''
    Key 55 AA
    Eltorito defaultboot header:
        Bootid 88 (bootable)
        Boot media 0 (No Emulation Boot)
        Load segment 0
        Sys type 0
        Nsect 4
        Bootoff 30 48

and, notwithstanding, the CD does NOT boot. Any ideas?
