15The 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
24Setting 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

65The ICN driver may be built into the kernel or as a module. Initialization
66depends on how the driver is built:
67
68Driver 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
97Driver 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
119Loading 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.
