  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

  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 dowloading 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.
