I'm using the same PCMCIA cd controller as you and I have the same setup as you (except a Blizzard 1260)
I used the CD1200 install disk that came with the Alfa data cd controller, If I use IDEFIX straight away after the WB install the "find device" in the package can't find the cd-rom.
Please give a little but more detailed information how you did when you installed the cd-rom drive/software for it.
