SECTION 1.0 Installation
=====================================================================
This section describes issues that are specific to the installation
of your Megahertz PCMCIA Ethernet Adapter.
*************************
1.1: The Install Program
*************************
To run install, at the DOS prompt type:
A:INSTALL
Follow the instructions...
The install program can set up your computer with the software that
is necessary to enable your PCMCIA Ethernet Adapter. Install will
also assist you with specific setup requirements of your Network
Operating System.
*******************************************
1.2: Overview Of PCMCIA Enabling Software
*******************************************
All PCMCIA input/output devices must be enabled by software before
they can be used. This enabling process must be repeated (that is,
the enabling process must be executed again) whenever the PCMCIA
adapter has been powered off. A PCMCIA adapter will be powered off
when the user removes it from the computer. It may also be powered
off when the computer goes into a "sleep" mode to conserve power.
There are two kinds of PCMCIA enabling software:
* point enablers
* Card and Socket Services
Point Enablers
--------------
Point enablers are programs that run, enable a specific device (such
as a PCMCIA modem or Ethernet adapter), and exit back to DOS without
remaining resident in RAM. Point enabler commands are typically
installed so that they will be executed once each time the computer
is turned on or re-booted.
The advantage of a point enabler is that it uses system memory only
while it runs and does not remain resident in memory after its
execution. The disadvantage is that if the PCMCIA device is
powered off, then the user must remember to execute the point enabler
command to re-enable the adapter. Another disadvantage of point
enablers is that you need a different one for each manufacturer's
PCMCIA device. One manufacturer's point enabler may conflict with
another point enabler.
Card and Socket Services
------------------------
Card and Socket Services is a set of programs which are installed so
that they are executed when the computer is turned on. The Card and
Socket Services programs then stay resident - they remain in memory
all of the time. Card and Socket Services are designed to detect
when a PCMCIA device has been removed and then automatically
re-enable the card when it is re-inserted. This allows "hot swapping"
you can pull a PCMCIA card out and put in a different one and the
new card is automatically enabled. Card and Socket Services are also
capable of enabling devices from different manufacturers and attempt to
prevent all conflicts between different PCMCIA cards.
The main disadvantage of Card and Socket Services is that they
permanently occupy a certain amount of computer memory which could be
used by other programs. However, because of the resource conflict
management capability, we recommend you use Card and Socket Services.
*****************************************
1.3 Installing Card and Socket Services
*****************************************
NOTE: If you are not familiar with PCMCIA enabling software such as
Card and Socket Services, it may be helpful to read section 1.2.
For all users:
--------------
If your computer comes with Card and Socket Services, it probably
already supports your PCMCIA Ethernet adapter. The install program
will check if there are any Card and Socket Services currently
installed on your computer and verify that they can enable your
Ethernet adapter. You can also choose to install the Card and
Socket Services that are included on the Megahertz installation
disk or you can install the Card and Socket Services that may have
come with your computer according to your computer's documentation.
If your computer does not come with Card and Socket Services, or if
your version of Card and Socket Services does not support this
PCMCIA Ethernet adapter, you can install enabling software which is
shipped with this product. For this purpose, there is setup utility
called INSTALL, a menu-driven installation program for non-technical
users or for users who are happy with a standard configuration.
NOTE: If you use INSTALL to configure the Card and Socket Services
which come with the Megahertz PCMCIA Ethernet adapter, it will
disable (comment out) any existing Card and Socket Services drivers
which it locates.
INSTALL automatically creates directories, copies files, and modifies
CONFIG.SYS, AUTOEXEC.BAT, and SYSTEM.INI (for Microsoft Windows).
For technical users:
--------------------
The instructions below are intended for technical users who prefer to
make their own configuration modifications.
You have the option of installing Card and Socket Services or a
point enabler.
How to Install Card and Socket Services
---------------------------------------
1. If you are using an expanded memory manager (e.g., EMM386.EXE),
make sure that you exclude the memory range D000-DFFF from control of
the memory manager. The Card and Socket Services use this memory
window.
2. Comment out any existing Card and Socket Services drivers from
your CONFIG.SYS file.
3. Create a directory (e.g. C:\MEGZENET ) on your hard disk. Copy
the following files from the diskette to that directory:
SS365SL.EXE
CS.EXE
CSALLOC.EXE
CARDID.EXE
CARDID.INI
CARDID.CLB
(If your computer has a Databook PCMCIA controller, copy SSDBOOK.EXE
instead of SS365SL.EXE; if you have a Cirrus Logic controller, copy
SSCIRRUS.EXE instead of SS365SL.EXE.)
To determine which type PCMCIA controller that is used in your
computer, please check your computer manufacturers manuals.
4. Create a second directory (e.g. C:\MEGZENET\WIN ) to hold the
Windows drivers. Copy the following files from the diskette to that
directory:
SSVCD.386
SSVRDD.386
SSCOMM.DRV
5. Add the following lines to CONFIG.SYS:
DEVICE=C:\MEGZENET\SS365SL.EXE /ADA=0
DEVICE=C:\MEGZENET\CS.EXE
DEVICE=C:\MEGZENET\CSALLOC.EXE C:\MEGZENET\CSALLOC.INI
DEVICE=C:\MEGZENET\CARDID.EXE
(If your computer has a Databook PCMCIA controller, use SSDBOOK.EXE
instead of SS365SL.EXE; if you have a Cirrus Logic controller, use
SSCIRRUS.EXE instead of SS365SL.EXE.)
6. Change to the MEGZENET directory. Remove all PC cards from all
PCMCIA slots on your computer. Then type the following command:
CSALLOC /G
This takes a "snapshot" of your system configuration and will create
the CSALLOC.INI initialization file.
7. Edit your SYSTEM.INI file.
In the [boot] section, replace the line
comm.drv=comm.drv
with
comm.drv=C:\MEGZENET\WIN\SSCOM.DRV
In the [386Enh] section, replace the line
device=*vcd
with
;device=*vcd
If you have other custom virtual communications drivers in your
SYSTEM.INI file, you may need to comment them out as well. (The
symptom that indicates this needs to be done is that you get
"duplicate driver" messages when you try to run Windows after step 8,
below.) For example, if you do not have the line
device=*vcd
but you do have a line which reads
device=xyzvcd
you may need to comment it out:
;device=xyzvcd
Most virtual communications drivers will have "vcd" somewhere in the
name but unfortunately this is not guaranteed.
In the [386Enh] section, add the following lines:
device=C:\MEGZENET\WIN\SSVRDD.386
device=C:\MEGZENET\WIN\SSVCD.386
COM1Base=3F8
COM1Irq=4
COM2Base=2F8
COM2Irq=3
COM3Base=3E8
COM3Irq=4
COM4Base=2E8
COM4Irq=3
8. Reboot your computer.
************************************
1.4. Installing Point Enablers
************************************
1. First determine which type of PCMCIA controller that is used in
your computer by checking your computer manufacturer's documentation.
2. There are three different point enablers on the Megahertz
Installation Diskette:
INTEL.EXE Intel SS365SL or Cirrus Logic CL-PD6710/6712
DATABOOK.EXE Databook TCIC-2N
TOSHIBA.EXE Proprietary Toshiba T3300
3. The point enablers can be executed from your AUTOEXEC.BAT or
CONFIG.SYS. Some NDIS-based Network Operating Systems require that
the NDIS Ethernet Driver (SMC9000.DOS) be loaded in the CONFIG.SYS.
Since commands that reside in CONFIG.SYS are executed before those
in the AUTOEXEC.BAT, you must execute the proper ENABLER for your
machine from the CONFIG.SYS for these NDIS systems. If you have
problems you may want to call your Network Operating Systems
technical support.
4. To enable your PCMCIA Ethernet adapter from the CONFIG.SYS each
time your machine boots, use a text editor to add the proper ENABLER
for your computer to your CONFIG.SYS. This line must follow any
expanded memory managers and be before the loading of any network
drivers.
o
o
o
DEVICE=C:\MEGZENET\ENABLER.EXE /S:0 /PORT:300 /IRQ:5 /ATTR:D000
o
o
o
5. To enable your PCMCIA Ethernet adapter from the AUTOEXEC.BAT each
time your machine boots, use a text editor to add the proper
ENABLER for your computer to your AUTOEXEC.BAT. This line must
proceed any network drivers.
o
o
o
C:\MEGZENET\ENABLER /S:0 /PORT:300 /IRQ:5 /ATTR:D000
o
o
o
6. IMPORTANT: Be sure that the point enabler options that you
specify match those specified in the parameter file for your Network
Operating System (NET.CFG for ODI and PROTOCOL.INI for NDIS).
The default values are:
PORT 300 (I/O port address)
IRQ 5 (Hardware interrupt)
S 0 (Slot 1 or A)
7. The "/S" switch indicates which PCMCIA slot contains your Ethernet
adapter. Most manufacturers refer to their first slot as slot 1 or
slot B but this parameter is 0 based. Slot 1 = 0 and Slot 2 = 1.
On computers with more than one slot, there is no standard about
which one will be slot 0 and which is slot 1. Usually they are not
labeled. You may need to find out through trial and error.
8. The "/PORT" switch indicates the I/O base address in hexadecimal
that is used by the adapter. Values can range from 200 to 3E0 and
must be on a 20 byte boundary (i.e. 300, 320, 340, etc.)
9. The "/IRQ" switch indicates the hardware interrupt in hexadecimal
that is used by the adapter. The following values can be used on
most computers: 3, 4, 5, 7, 9, A, B, C, F.
10. The "/ATTR" switch indicates what memory window the ENABLER
program will use for communication with your Ethernet adapter. The
four-character number following the /ATTR is a hexadecimal address.
If you have a memory conflict at the default D000 range, you could
change it to something else like D800.
11. If you are not using an expanded memory manager such as
EMM386.SYS, skip this step.
If you are using an expanded memory manager such as EMM386.SYS, you
must exclude the memory range you specified in step 2. (Each expanded
memory manager has a command line switch which allows you to exclude
a range of memory addresses from the memory manager's control. See
your memory manager documentation for the exact form of the command
line switch.) If you used the default D000 in step 2, you must
exclude the range D000-D1FF; if you used D800, you must exclude
D800-D9FF, etc.
If you are using an expanded memory manager before you run Microsoft
Windows, you must also add an "EMMExclude" line to the [386Enh]
section of your SYSTEM.INI file to inform Windows of the excluded
range:
o
o
o
[386Enh]
o
o
EMMExclude=D000-D1FF
o
o
o
12. Insert your Ethernet adapter in the slot you specified and reboot.
Your Ethernet adapter should be recognized. Note that since this is a
point enabler, you will need to re-run the enabler command line with
the appropriate switches each time your computer goes to sleep or each
time you remove and re-insert the adapter.
