   3This document describes the ACT2000 driver for the
   4IBM Active 2000 ISDN card.
   5
   6There are 3 Types of this card available. A ISA-, MCA-, and PCMCIA-Bus
   7Version. Currently, only the ISA-Bus version of the card is supported.
   8However MCA and PCMCIA will follow soon.
   9
  10The ISA-Bus Version uses 8 IO-ports. The base port address has to be set
  11manually using the DIP switches.
  12
  13Setting up the DIP switches for the IBM Active 2000 ISDN card:
  14
  15         Note: S5 and S6 always set off!

  30     off on  off off 0xcea0 
  31     on  off off off 0xce60 
  32     off off off off Card disabled 
  33
  34IRQ is configured by software. Possible values are:
  35
  36  3, 5, 7, 10, 11, 12, 15 and none (polled mode)
  37
  38
  39The ACT2000 driver may either be built into the kernel or as a module.
  40Initialization depends on how the driver is built:
  41
  42Driver built into the kernel:
  43
  44  The ACT2000 driver can be configured using the commandline-feature while
  45  loading the kernel with LILO or LOADLIN. It accepts the following syntax:
  46
  47  act2000=b,p,i[,idstring]
  48
  49  where
  50
  51    b = Bus-Type      (1=ISA, 2=MCA, 3=PCMCIA)
  52    p = portbase      (-1 means autoprobe)
  53    i = Interrupt     (-1 means use next free IRQ, 0 means polled mode)
  54
  55  The idstring is an arbitrary string used for referencing the card
  56  by the actctrl tool later.
  57
  58  Defaults used, when no parameters given at all:
  59
  60    1,-1,-1,""
  61
  62  which means: Autoprobe for an ISA card, use next free IRQ, let the
  63  ISDN linklevel fill the IdString (usually "line0" for the first card).
  64 
  65  If you like to use more than one card, you can use the program
  66  "actctrl" from the utility-package to configure additional cards.
  67
  68  Using the "actctrl"-utility, portbase and irq can also be changed
  69  during runtime. The D-channel protocol is configured by the "dproto"
  70  option of the "actctrl"-utility after loading the firmware into the
  71  card's memory using the "actctrl"-utility.
  72
  73Driver built as module:
  74
  75  The module act2000.o can be configured during modprobe (insmod) by
  76  appending its parameters to the modprobe resp. insmod commandline.
  77  The following syntax is accepted:
  78
  79    act_bus=b act_port=p act_irq=i act_id=idstring
  80
  81  where b, p, i and idstring have the same meanings as the parameters
  82  described for the builtin version above.
  83
  84  Using the "actctrl"-utility, the same features apply to the modularized
  85  version as to the kernel-builtin one. (i.e. loading of firmware and
  86  configuring the D-channel protocol)
  87
  88Loading the firmware into the card:
  89
  90  The firmware is supplied together with the isdn4k-utils package. It
  91  can be found in the subdirectory act2000/firmware/
  92
  93  Assuming you have installed the utility-package correctly, the firmware
  94  will be downloaded into the card using the following command:
  95
  96    actctrl -d idstring load /etc/isdn/bip11.btl
  97
  98  where idstring is the Name of the card, given during insmod-time or
  99  (for kernel-builtin driver) on the kernel commandline. If only one
 100  ISDN card is used, the -d isdstrin may be omitted.
 101
 102  For further documentation (adding more IBM Active 2000 cards), refer to
 103  the manpage actctrl.8 which is included in the isdn4k-utils package.
