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

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.
