23  * Card:	Chip:		Configuration:	Comment:
24  * ---------------------------------------------------------------------
25  * Speed Card	ISAC_HSCX	DIP-SWITCH
26  * Speed Win	ISAC_HSCX	ISAPNP
27  * Speed Fax+	ISAC_ISAR	ISAPNP		Full analog support
28  * Speed Star	ISAC_HSCX	CARDMGR
29  * Speed Win2	IPAC		ISAPNP
30  * ISDN PC/104	IPAC		DIP-SWITCH
31  * Speed Star2	IPAC		CARDMGR
32  * Speed PCI	IPAC		PCI PNP
33  * Speed Fax+ 	ISAC_ISAR	PCI PNP		Full analog support
34  *
35  * Important:
36  * For the sedlbauer speed fax+ to work properly you have to download
37  * the firmware onto the card.
38  * For example: hisaxctrl <DriverID> 9 ISAR.BIN
