not sure about your question. Heres the answer on the disk vs slot issue
Flash memory cards use similar commands. The primary syntax change is that disk0: or disk1: refers to Flash memory ATA disks, while slot0: or slot1: refers to Flash memory cards. Generally, use the syntax slot0: for Flash memory cards less than 20 MB, and use disk0: for Flash disk greater than 20 MB. Keep in mind that there are 32 MB linear PCMCIA Flash cards where you use slot0.
