Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

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) | ||

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. | ||
