 * ---------------------------------------------------------------------
 * Speed Card     ISAC_HSCX   DIP-SWITCH
 * Speed Win      ISAC_HSCX   ISAPNP
 * Speed Fax+     ISAC_ISAR   ISAPNP            Full analog support
 * Speed Star     ISAC_HSCX   CARDMGR
 * Speed Win2     IPAC        ISAPNP

 * Important:
 * For the sedlbauer speed fax+ to work properly you have to download
