10/100 Fast Ethernet CardBus PC Card
Windows 95 Driver Installation
Overview
--------
Windows 95 versions 950 and 950a (OSR1) do not have built-in support for
CardBus Cards. When you insert a CardBus card into a socket under these
systems, they do not recognize the card. In these systems you have to
install a CardBus card manually as a legacy (non-plug-and-play) card.
The Windows 95 version 950B (OSR2) and its successor, the operating
system with the code name Memphis, do recognize CardBus cards. These
systems also support the hot-swap capability. This means you can
insert or remove a CardBus card while the system is running without
disrupting the system's other services.
Before you install the Accton EN2220 CardBus PC Card for the Windows 95
OSR2 version, please make sure the driver for the CardBus socket
controller is installed correctly. This can be verified by carrying out
these steps:
1) Double click on the "Control Panel" icon. In the "Control Panel"
window, double click on the "System" icon.
2) In the "System Properties" window, click on the "Device Manager"
tab.
3) In the "Device manager" listed tree view box, look for the
"PCMCIA socket" item. If this item cannot be found, the CardBus
socket controller driver is not installed. You should install this
driver first. If the item is found, click on the "+" sign next to
the "PCMCIA socket" item, and the name of the CardBus controller is
displayed. Please make sure there is not a cross mark or an
exclamation mark on top of the CardBus socket controller name. If
there is, you have to reinstall the driver for the CardBus controller.
Two adapter names are provided in the installation information
file (ACC2220.INF):
1) "Accton EN2220 Fast Ethernet CardBus PC Card"
-- for Windows 95 OSR2 and Memphis. See item (A) in the
"Driver Installation Procedure" section below.
2) "Accton EN2220 Fast Ethernet CardBus PC Card (Manual Load)"
-- for Windows 95 and OSR1. See item (B) in the "Driver
Installation Procedure" section.
Driver Installation Procedure:
-----------------------------
A) Driver installation for Windows 95 OSR2 version
B) Driver installation for Windows 95 and OSR1
A) Driver installation for Windows 95 OSR2 version
1. Bring up an MS-DOS command window. Enter the following
DOS commands:
CD %windir%\INF
RENAME NETPCI.INF *.IN_
EXIT
2. Insert the Accton EN2220 card in one of the CardBus sockets. Attach
the coupler to the back of the card, and connect a cable from the
RJ-45 connector at the back of the coupler to a hub or switch.
Note if you are attaching to a 100 Mbps network, the cable has to
have the grading of CAT-5.
3. Windows 95 displays the "New Hardware Found" window, with "PCI
Ethernet Controller" as the device name.
4. Windows 95 displays the "Update Device Driver Wizard" window, with
the message "This wizard will complete the installation of:
PCI Ethernet Controller." Click the "Next>" button.
5. The "Update Device Driver Wizard" displays the message: "Windows
found the following updated driver for this device: Accton EN2220
Fast Ethernet CardBus PC Card." Click the "Finish" button.
6. Windows 95 displays the "Insert Disk" warning message box, with
the message: "Please insert the disk labeled 'Accton EN2220 Fast
Ethernet CardBus PC Card Driver Diskette,' and then click OK."
Click the OK button.
7. Windows 95 displays the "Copying files..." box. In the "Copy
files from:" edit box, enter the diskette path name, i.e.
A:\ (or B:\). Click the OK button.
8. Windows 95 copies the necessary files from the driver diskette and
the Windows 95 CD-ROM to the system directories on the hard disk.
If Windows 95 asks for the location of the Windows 95 CD-ROM,
please specify the location of it. Wait until the installation
process is completed.
9. Shutdown and restart the computer.
10. The driver is installed. Now each time when you insert an
EN2220 card in a CardBus socket in your notebook, Windows 95 will
load the EN2220 driver automatically and bring up the network
function. Please note EN2220 must be properly connected to a
hub or switch when you insert the card in the socket; otherwise the
card and driver would not come up correctly.
B) Driver installation for Windows 95 and OSR1
1. From the Windows 95 desktop, double click on "My Computer",
"Control Panel", and "Network" icons.
2. From the Network dialog box, Click "Add", "Adapter", "Add", and
"Have Disk." The "Install from diskette" dialog box appears.
3. Insert the Accton EN2220 Driver Diskette in the floppy drive.
4. Enter the diskette path name, i.e. A:\ (or B:\). Click the OK
button.
5. Select "Accton EN2220 Fast Ethernet CardBus PC Card (Manual Load)"
from the list. Click the OK button.
6. This step assigns resources to the EN2220 card. In the Network
window, select "Accton EN2220 Fast Ethernet CardBus PC Card
(Manual Load)" from the list. Click the Property button, and
then click the Resource tab.
You then have to assign non-conflicting values for three types of
resources: I/O port, IRQ, and memory mapped address. In the
resource value edit box, if an '*' appears next to the resource
value, it indicates this resource is in use by another device in the
system, and EN2220 should not attempt to use it. You can use the
up and down arrows to the right of the edit box to select another
value of the resource until the '*' goes away.
When you are done, click the OK button.
7. In most cases, the default values assigned to the EN2220
configuration parameters work just fine. However, If you need to
fine-tune the driver, please carry out the steps listed in the
"Driver Configuration Procedure" below.
8. In the Network window, click the OK button. Windows 95 then copies
files from the driver diskette and the Windows 95 CD-ROM to
system directories on the hard disk. If Windows 95 asks for the
Windows 95 CD-ROM, please specify the location of it. Wait until
the installation process is completed.
9. Insert the Accton EN2220 card in one of the CardBus sockets. Attach
the coupler to the back of the card, and connect a cable from the
RJ-45 connector at the back of the coupler to a hub or switch.
Note if you are attaching to a 100 Mbps network, the cable has to
have the grading of CAT-5.
You can now shutdown and restart the computer. It is always advised
to do a cold-boot (turn the power off and on) when you restart
Windows 95. Please also note at Windows 95 initialization, the Fast
Ethernet CardBus PC Card must be properly connected to a hub or
switch; otherwise the card and driver would not come up correctly.
Driver Configuration Procedure:
------------------------------
1. Click the "My Computer" icon.
2. Click the "Control Panel" icon in the "My Computer" window.
3. Click the "Network" icon from the "Control Panel" window.
4. Select "Accton EN2220 Fast Ethernet CardBus PC Card" from Network
Components list box. Click the "Properties" button.
5. Click the "Advanced" tab. From the "Property" selection list,
you can configure the following properties:
Common parameters for Windows 95, OSR1, and OSR2
------------------------------------------------
<1> 100Mbps Transmit Threshold:
Set the NIC Transmit FIFO threshold for
100Mbps line speed. The default value is 128 bytes.
<2> 10Mbps Transmit Threshold:
Set the NIC Transmit FIFO threshold for
10Mbps line speed. The default value is 96 bytes.
<3> Burst Length:
Set the PCI bus memory read/write burst
length. The default value is 16 Dwords.
(1 Dword = 4 bytes.)
<4> Connection Type:
Set the medium attached. Default is AutoSense.
<5> Map Registers:
This parameter is machine dependent.
The Default value is 8.
<6> Memory Read Multiple:
Enable the PCI bus Memory Read Multiple feature.
Default is "Disable."
<7> Receive Buffers:
Set the number of NIC receive buffers.
The default value is 16.
<8> Snooze Mode:
Enable the snooze mode can force the NIC to low power
state. Default is "Disable."
<9> Store And Forward:
Enable this parameter will cause NIC to disable the
transmit data pipeline operation. Default is "Enable."
<10> Underrun Max Retries:
Set the maximum retry count after transmit FIFO underrun.
Machine dependent parameters for Windows 95 and OSR1.
-----------------------------------------------------
<1> Socket Number:
Specify in which socket a EN2220 is inserted.
Default is "Auto detect."
<2> Interrupt Style:
Specify the CardBus bridge interrupt routing strategy.
Default is "PCI-IRQ-Routed."
<3> PCI Interrupt Routing:
Specify which interrupt pin is used while the CardBus
bridge is using "PCI-IRQ-Routed." Default is "INT A."
It is extremely important to assign correct values to the IRQ
value and the "Interrupt_Style" parameter. If the system uses the
"PCI-IRQ-Routed" interrupt style, it is also important to assign the
correct PCI "Interrupt_Routing" value (i.e. INT A or INT B.)
If in doubt about the values to assign to these parameters, you are
advised to execute the CBOPEN.EXE card enabling program in a native
MS-DOS system first. CBOPEN.EXE displays the IRQ value used, as
well as the system's interrupt style. For the Windows 95 driver,
you should assign the same values to the above parameters as those
displayed by CBOPEN.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
