Personally I think that is a "bug" in FILO.
    "hdx"   refers to the entire device "x"
    "hdx1"  refers to the first primary partition of "x"
    "hdx2"  refers to the second primary partition of "x"

And since you can't partition a CD-ROM ( or DVD for that mater ) "hdb"
should be correct.

reference: "man fdisk", etc.
