+
+This document describes the ACT2000 driver for the
+IBM Active 2000 ISDN card.
+
+There are 3 Types of this card available. A ISA-, MCA-, and PCMCIA-Bus
+Version. Currently, only the ISA-Bus version of the card is supported.
+However MCA and PCMCIA will follow soon.
+
+The ISA-Bus Version uses 8 IO-ports. The base port address has to be set
+manually using the DIP switches.
+
+Setting up the DIP switches for the IBM Active 2000 ISDN card:
+
+ Note: S5 and S6 always set off!
+
+ S1 S2 S3 S4 Base-port
+ on on on on 0x0200 (Factory default)
+ off on on on 0x0240
+ on off on on 0x0280
+ off off on on 0x02c0
+ on on off on 0x0300
+ off on off on 0x0340
+ on off off on 0x0380
+ on on on off 0xcfe0
+ off on on off 0xcfa0
+ on off on off 0xcf60
+ off off on off 0xcf20
+ on on off off 0xcee0
+ off on off off 0xcea0
+ on off off off 0xce60
+ off off off off Card disabled
+
+IRQ is configured by software. Possible values are:
+
+ 3, 5, 7, 10, 11, 12, 15 and none (polled mode)
+
+
+The ACT2000 driver may either be built into the kernel or as a module.
+Initialization depends on how the driver is built:
+
+Driver built into the kernel:
+
+ The ACT2000 driver can be configured using the commandline-feature while
+ loading the kernel with LILO or LOADLIN. It accepts the following syntax:
+
+ act2000=b,p,i[,idstring]
+
+ where
+
+ b = Bus-Type (1=ISA, 2=MCA, 3=PCMCIA)
+ p = portbase (-1 means autoprobe)
+ i = Interrupt (-1 means use next free IRQ, 0 means polled mode)
+
+ The idstring is an arbitrary string used for referencing the card
+ by the actctrl tool later.
+
+ Defaults used, when no parameters given at all:
+
+ 1,-1,-1,""
+
+ which means: Autoprobe for an ISA card, use next free IRQ, let the
+ ISDN linklevel fill the IdString (usually "line0" for the first card).
+
+ If you like to use more than one card, you can use the program
+ "actctrl" from the utility-package to configure additional cards.
+
+ Using the "actctrl"-utility, portbase and irq can also be changed
+ during runtime. The D-channel protocol is configured by the "dproto"
+ option of the "actctrl"-utility after loading the firmware into the
+ card's memory using the "actctrl"-utility.
+
+Driver built as module:
+
+ The module act2000.o can be configured during modprobe (insmod) by
+ appending its parameters to the modprobe resp. insmod commandline.
+ The following syntax is accepted:
+
+ act_bus=b act_port=p act_irq=i act_id=idstring
+
+ where b, p, i and idstring have the same meanings as the parameters
+ described for the builtin version above.
+
+ Using the "actctrl"-utility, the same features apply to the modularized
+ version as to the kernel-builtin one. (i.e. loading of firmware and
+ configuring the D-channel protocol)
+
+Loading the firmware into the card:
+
+ The firmware is supplied together with the isdn4k-utils package. It
+ can be found in the subdirectory act2000/firmware/
+
+ Assuming you have installed the utility-package correctly, the firmware
+ will be downloaded into the card using the following command:
+
+ actctrl -d idstring load /etc/isdn/bip11.btl
+
+ where idstring is the Name of the card, given during insmod-time or
+ (for kernel-builtin driver) on the kernel commandline. If only one
+ ISDN card is used, the -d isdstrin may be omitted.
+
+ For further documentation (adding more IBM Active 2000 cards), refer to
+ the manpage actctrl.8 which is included in the isdn4k-utils package.
