15	The card communicates with the PC by two interfaces:
16	  1. A range of 4 successive port-addresses, whose base address can be 
17	     configured with the switches.
18	  2. A memory window with 16KB-256KB size, which can be setup in 16k steps
19	     over the whole range of 16MB. Isdn4linux only uses a 16k window.
20	     The base address of the window can be configured when loading
21	     the lowlevel-module (see README). If using more than one card,
22	     all cards are mapped to the same window and activated as needed.
23	
24	Setting up the IO-address dipswitches for the ICN-ISDN-card:
25	
26	  Two types of cards exist, one with dip-switches and one with
27	  hook-switches.
28	
29	  1. Setting for the card with hook-switches:
30	
31	     (0 = switch closed, 1 = switch open)
32	
33	     S3 S2 S1  Base-address
34	      0  0  0  0x300
35	      0  0  1  0x310
36	      0  1  0  0x320 (Default for isdn4linux)
37	      0  1  1  0x330
38	      1  0  0  0x340
39	      1  0  1  0x350
40	      1  1  0  0x360
41	      1  1  1  NOT ALLOWED!
42	    
43	  2. Setting for the card with dip-switches:
44	
45	     (0 = switch closed, 1 = switch open)
46	
47	     S1 S2 S3 S4  Base-Address
48	      0  0  0  0  0x300

54	      0  1  1  0  0x360
55	      0  1  1  1  NOT ALLOWED!
56	      1  0  0  0  0x308

65	The ICN driver may be built into the kernel or as a module. Initialization
66	depends on how the driver is built:
67	
68	Driver built into the kernel:
69	
70	  The ICN driver can be configured using the commandline-feature while
71	  loading the kernel with LILO or LOADLIN. It accepts the following syntax:
72	
73	  icn=p,m[,idstring1[,idstring2]]
74	
75	  where
76	
77	    p = portbase      (default: 0x320)
78	    m = shared memory (default: 0xd0000)
79	
80	  When using the ICN double card (4B), you MUST define TWO idstrings.
81	  idstring must start with a character! There is no way for the driver
82	  to distinguish between a 2B and 4B type card. Therefore, by supplying
83	  TWO idstrings, you tell the driver that you have a 4B installed.
84	  
85	  If you like to use more than one card, you can use the program
86	  "icnctrl" from the utility-package to configure additional cards.
87	  You need to configure shared memory only once, since the icn-driver
88	  maps all cards into the same address-space.
89	
90	  Using the "icnctrl"-utility, portbase and shared memory can also be
91	  changed during runtime.
92	
93	  The D-channel protocol is configured by loading different firmware
94	  into the card's memory using the "icnctrl"-utility.
95	
96	
97	Driver built as module:
98	
99	  The module icn.o can be configured during "insmod'ing" it by
100	  appending its parameters to the insmod-commandline. The following
101	  syntax is accepted:
102	
103	    portbase=p membase=m icn_id=idstring [icn_id2=idstring2]
104	
105	  where p, m, idstring1 and idstring2 have the same meanings as the
106	  parameters described for the kernel-version above.
107	      
108	  When using the ICN double card (4B), you MUST define TWO idstrings.
109	  idstring must start with a character! There is no way for the driver
110	  to distinguish between a 2B and 4B type card. Therefore, by supplying
111	  TWO idstrings, you tell the driver that you have a 4B installed.
112	  
113	  Using the "icnctrl"-utility, the same features apply to the modularized
114	  version like to the kernel-builtin one.
115	
116	  The D-channel protocol is configured by loading different firmware
117	  into the card's memory using the "icnctrl"-utility.
118	
119	Loading the firmware into the card:
120	
121	  The firmware is supplied together with the isdn4k-utils package. It
122	  can be found in the subdirectory icnctrl/firmware/
123	
124	  There are 3 files:
125	
126	    loadpg.bin   - Image of the bootstrap loader.
127	    pc_1t_ca.bin - Image of firmware for german 1TR6 protocol.
128	    pc_eu_ca.bin - Image if firmware for EDSS1 (Euro-ISDN) protocol.
129	
130	  Assuming you have installed the utility-package correctly, the firmware
131	  will be downloaded into the 2B-card using the following command:
132	
133	    icnctrl -d Idstring load /etc/isdn/loadpg.bin /etc/isdn/pc_XX_ca.bin
134	
135	  where XX is either "1t" or "eu", depending on the D-Channel protocol
136	  used on your S0-bus and Idstring is the Name of the card, given during
137	  insmod-time or (for kernel-builtin driver) on the kernel commandline.
138	
139	  To load a 4B-card, the same command is used, except a second firmware
140	  file is appended to the commandline of icnctrl.
141	
142	  -> After downloading firmware, the two LEDs at the back cover of the card
143	     (ICN-4B: 4 LEDs) must be blinking intermittently now. If a connection
144	     is up, the corresponding led is lit continuously.
145	
146	  For further documentation (adding more ICN-cards), refer to the manpage
147	  icnctrl.8 which is included in the isdn4k-utils package.
