/* Supported cards:
 * Card:	Chip:		Configuration:	Comment:
 * ---------------------------------------------------------------------
 * 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
 * ISDN PC/104	IPAC		DIP-SWITCH
 * Speed Star2	IPAC		CARDMGR
 * Speed PCI	IPAC		PCI PNP
 * Speed Fax+ 	ISAC_ISAR	PCI PNP		Full analog support
 *
 * Important:
 * For the sedlbauer speed fax+ to work properly you have to download
 * the firmware onto the card.
 * For example: hisaxctrl <DriverID> 9 ISAR.BIN
