The floppy drive must be set to drive-0. And what about the HDD? Is it working?

Disable the on-board IDE and try again. Also, you should mod the clock chip or add a modern clock chip like the Necroware's nwX287.

You either have to disable the on-board IDE controller or disable the IDE portion of the I/O card.

Well, are you sure the card is in working condition? Have you considered buying a new floppy drive controller?
