DESCRIPTION
This reference page provides detailed instructions on adding PCMCIA card
support to certain processors.
Supported Configurations
PCMCIA (PC Card) support is limited to the following capabilities:
· Support of selected ISA to PCMCIA bridge adapters
· Support on the following platforms:
-- AlphaStation 255
-- AlphaStation 200
-- AlphaStation 400
-- AlphaStation 600
-- AlphaServer 1000
· One modem card, specifically Megahertz XJ2288 (28.8kpbs)
· Hot swap capability of PC Cards.
Configuring a PCMCIA Adapter Board from the Console
Before inserting the PCMCIA adapter board into your system, make sure to
read the manual that came with the adapter from the adapter vendor and
follow the instructions on how to connect the cables and install the board.
Check your system documentation to find out what kind of bus is available
in your system and use the appropriate ISA or EISA instructions.
Configuring a PCMCIA on an ISA Bus System
If your system has an ISA (Industry Standard Architecture) bus, use the
following procedure to configure a card:
1. If the system is an ISA bus system, the isacfg utility from the
console must be used to configure the PCMCIA adapter.
2. Insert the PCMCIA adapter board in an ISA slot in the system and turn
on the system.
3. To add a PCMCIA option to the platforms with an ISA bus, issue the
following ISA option card configuration command at the console. The
following example uses an AlphaStation 200 platform, but the commands
should be the same in all three ISA bus platforms.
>>> isacfg -slot 1 -etyp 1 -dev 0 -mk -iobase0 3e0 /
-irq0 14 -enadev 1 -handle PCIC-PCMCIA
If the system is already using slot 1, select an unused slot number.
4. The IRQ (interrupt) number must not conflict with interrupt numbers
assigned to other default devices on the system. The system hardware
manual usually indicates which IRQ numbers are already assigned.
5. The recommended IRQ number for the PCMCIA adapter is 14 (decimal). If
IRQ 14 is already used, the next best choice is IRQ 10 (if 10 is not
already used by other devices).
6. When you issue the above isacfg command, the console should print out
the following line or something similar:
type >>>init to use these changes
After reinitializing the console, you can verify that you configured
the PCMCIA adapter correctly by issuing the following command:
>>>isacfg -slot 1
7. You should see the following screen display:

Configuring a PCMCIA on an EISA Bus System
If you are installing the PCMCIA adapter on a computer with an EISA
(Extended Industry Standard Architecture) bus, use the EISA Configuration
Utility (ECU) to configure it. Invoke the EISA Configuration Utility (ECU),
and specify that the PCMCIA adapter is present. Next, provide a pointer to
the aisa3000.cfg configuration file.
Refer to your system hardware documentation for complete instructions on
how to run the ECU program.
Setting up a PCMCIA Modem PC Card for Use
A PCMCIA Card is a dynamic device, not a static device that is present all
the time in the system hardware). The serial-line device driver is a
static device driver. Therefore, there will not be a corresponding acex
entry created automatically when the first custom kernel is configured.
This is because the system has no knowledge of the PCMCIA device at this
time.
To automatically create the acex entry for your PCMCIA fax/modem card:
· Ensure that you have the PCMCIA adapter configured in the console.
· Insert the PCMCIA fax/modem card into the slot.
For example, if you insert a fax/modem card in the slot 0 before
automatically building the initial target kernel, the resulting kernel
configuration file will contain the following line item:
controller ace2 at pcmcia0 slot 0 vector aceintr
The installation will also create the device special file for this
fax/modem card in the directory named /dev. Using the ls command, you can
display the file as follows:
# ls -gl /dev/tty02
crw-rw-rw- 1 root system 35, 2 Oct 16 13:22 tty02
If you did not have the PCMCIA fax/modem card inserted in the slot during
System installation, add the following line to your system kernel
configuration file (/sys/conf/HOSTNAME where HOSTNAME is the name of your
system):
controller ace2 at * slot ? vector aceintr
If you plan to use two modem cards simultaneously, add the following lines
to your system configuration file:
controller ace2 at * slot ? vector aceintr
controller ace3 at * slot ? vector aceintr
After modifying the system configuration file, use the following command to
rebuild the new kernel and reboot the system:
# doconfig -c
Creating a Device Special File for the Modem Card
Normally the system installation creates the following default tty0x device
special files in the directory /dev:
crw-rw-rw- 1 root system 35, 0 Oct 16 13:22 tty00
crw-rw-rw- 1 root system 35, 1 Oct 16 13:22 tty01
Two lines are present because most systems have two embedded serial lines.
A system with a single embedded serial line creates only one tty00 entry in
the /dev directory.
To create additional device special files for the PCMCIA modem cards, use
the MAKEDEV utility in the /dev directory. For example:
# ./MAKEDEV ace2
MAKEDEV: special file(s) for ace2:
tty02
The generated special file should look as follows:
crw-rw-rw- 1 root system 35, 2 Oct 27 14:02 tty02
If you intend to have two PCMCIA modem cards working simultaneously, create
device special files for each card. For example:
# ./MAKEDEV ace2 ace3
MAKEDEV: special file(s) for ace2:
tty02
MAKEDEV: special file(s) for ace3:
tty03
The generated special files should look as follows:
crw-rw-rw- 1 root system 35, 2 Oct 27 14:02 tty02
crw-rw-rw- 1 root system 35, 3 Oct 27 14:02 tty03
Updating the /etc/remote File
You must edit the /etc/remote file to add new access line definitions for
the PCMCIA modem cards. If you have a 28.8kpb modem card and will be using
the full speed, set the baud rate (br) to 38400 in the /etc/remote file as
follows:
line2:dv=/dev/tty02:br#38400:pa=none
Note that line2 can be any name you determine to be used with the tip
command to establish a connection.
Once you insert a PCMCIA modem card and the system configures the card, the
card can be used as for any other modem devices.
Inserting a PCMCIA Modem Card
To use a PCMCIA modem card, insert the card to one of the PC Card slots in
the PCMCIA adapter. Depending on the adapter type, there may be two front
access card slots or one front access and one rear access card slot. When
you insert the card into the slot 0, you should see the following message
on the console terminal (or the Console Log window if using X11):
# PCMCIA socket 0: card manufacturer: MEGAHERTZ
product name: XJ2288
Configured: serial unit 2, type=16550A
ace2 at pcmcia0
This example used the MEGAHERTZ XJ2288 fax/modem card.
When you insert a modem card, an error message such as the following may
appear on the Console Log window:
socket 0: card manufacturer: MEGAHERTZ, unknown modem card inserted
Using generic modem driver for this PC Card.
PCMCIA socket 0: card manufacturer: MEGAHERTZ
product name: XJ1144
socket 0: Couldn't find usable config. for this card.
Please eject this PC Card.
This error occurs if the card requires I/O resources that are already in
use by other components in the system. If you see this error message, eject
the card because it is not configured correctly. A possible solution is to
remove some other ISA/EISA devices in the system and reboot the system,
freeing I/O resources that may be required.
Removing a PCMCIA Modem Card
Once you are finished using the modem card, push the button next to the
card slot to eject it. You should see the following message on the console
terminal or console Log window:
# stray interrupt on unit=2, intr_id=0
PCMCIA socket 0: PC Card removed
This message is not always displayed when you eject the card. It only
happens if the serial line driver generates an interrupt when the card
ejected.
RESTRICTIONS
The following restrictions apply in this release:
· No support is provided for loadable device drivers for PC Cards.
· If the system does not have any available IRQ (interrupt) numbers to
assign to the PCMCIA devices, you cannot configure PCMCIA devices. To
support one PCMCIA adapter the system must have at least three unused
IRQ numbers available. One IRQ is for the adapter and the other two
are for each PCMCIA socket.
· Tru64 UNIX can support two PCMCIA adapters in a system provided that
the necessary resources are available. In some systems, availability
of interrupt lines will prohibit the use of multiple adapters. If you
have sufficient resources and are going to support two adapters,
configure the second adapter should to use the I/O address 3E2.
· To use fax functions in a fax/modem PC card, a commercial UNIX fax
application software program is required.
· The Megahertz XJ2288 is the only modem card fully qualified on Tru64
UNIX. However, other modem cards of similar type (both 14.4kpbs and
28.8kpbs) may work. The following is the list of modem cards that are
known to work:
-- Model XJ2288, from MEGAHERTZ
-- Model XJ1144, from MEGAHERTZ
-- KeepInTouch Cardcard from ATT Paradyne
-- PCMCIA V.32bis 14,400 Fax
· The selected ISA to PCMCIA bridge adapters are from SCM Microsystems.
The SWAPBOX CLASSIC X2 Model MMCD-D2, which has the following
features:
-- 3.5 inch front access
-- Two slots (type II + type III) PC card socket
-- Standard PC-AT 16-bit ISA bus interface
-- PCMCIA Revision 2.X and ExCA compliant
· The SWAPBOX PREMIUM COMBO Model MMCD-FC2 has the following features:
-- 3.5 inch, 1.44 Mbyte Floppy Drive Support.
-- One Type I, II, or III front-access PC card socket
-- One Type I, II, or III rear-access PC card socket
-- Standard PC-AT 16-bit ISA bus interface
-- PCMCIA Revision 2.X and ExCA compliant
Other ISA to PCMCIA bridge adapters using the Intel i82365SL or a
compatible device may also work.
