Windows 95 Driver Installation
*******************************************************************
The following step should be taken in order to use the
Digital Fast EtherWORKS PCI 10/100 in a system running
Windows 95:
1. Before inserting the card into your system boot Windows 95.
*******************************************************************
If the adapter was inserted in the system and Windows 95 was
booted after the DE500 adapter was installed in the system,
please do the following:
- From within Windows 95 double click on "My Computer",
followed by "Control Panel", then "Network".
- Under the heading "The following network components are
installed", check to see if there is a line which says
"PCI Fast Ethernet DECChip 21140 based adapter." If this
line exist, click on it and then click on "Remove".
- Select "OK" to exit from the network setup window.
- Proceed with steps 2 through 8.
*******************************************************************
2. Insert this driver disk into the floppy drive. From the
"Start" menu of Windows 95 select "Run". Next to where it
"Open:" appears in the dialog box, type "A:\SETUP". Click
on "OK" and the EZWORKS installation program will start.
3. Under "Select a Network Operating System" click on the
"Windows 95" line.
4. Click on the "Install" button in order to copy all the
necessary files onto the system.
5. Exit EZWORKS by clicking on "File" in the menu bar and then
"Exit".
6. Shutdown Windows 95 and power off the computer.
7. Insert the network adapter into the system and connect the
network cable to it.
8. Power the system back on and boot Windows 95. Windows 95
will automatically detect the card and start the drivers.
Follow any instructions that Windows 95 displays to complete
the installation process. Reboot if requested to do so by
Windows 95.
******************************************************************
User Configurable Parameters
******************************************************************
The Fast EtherWORKS PCI 10/100 NDIS 3 driver has three user
configurable parameters. To view or modify these double click on
"My Computer", then double click "Control Panel", and then double
click on "Network". A list should appear containing all the
installed network components. Included in this list should be the
Fast EtherWORKS PCI 10/100 adapter. Double click on the entry
for the PCI adapter and its properties will be displayed.
There are three pages in the properties box: Driver Type,
Bindings, and Advanced. Click on "Advanced" to see the user
configurable parameters for the adapter. All of the parameters
have a label before them specifying if the parameter applies
to the NDIS 2 or NDIS 3 driver. By default, the system will use
the NDIS 3 driver. The following is a list of these parameters
and what each does. *** Please note, under most conditions,
these parameter should not need to be modified. ***
Media Type:
This parameter is used to select which type of media is
connected to the adapter. There are 5 valid settings for
Media Type:
"AutoSense" - In this mode, the adapter attempts to automatically
determine which type of media is connected. This includes
both Speed (10 Mbps/100 Mbps) and Duplex Setting (Full/Half).
If the driver is unable to determine the Duplex Setting, it
will default to Half Duplex. This mode is not valid for
DE500-FA.
"10 Mbps-Full Duplex" - The driver will force the adapter to run
at 10 Mbps Full Duplex. This mode is not valid for DE500-FA.
"10 Mbps-Half Duplex" - The driver will force the adapter to run
at 10 Mbps Half Duplex. This mode is not valid for DE500-FA.
"100 Mbps-Full Duplex" - The driver will force the adapter to run
at 100 Mbps Full Duplex.
"100 Mbps-Half Duplex" - The driver will force the adapter to run
at 100 Mbps Half Duplex.
** Please note that the adapter should not be forced to Full
Duplex unless the equipment at the other end of the wire is
also set to Full Duplex **
Store and Forward:
This parameter is used to enable/disable the adapters ability to
start transmitting data onto the network before it has been
completely copied from system memory to the adapter card. Setting
this paramter to "Off" may cause transmit errors if PCI bus
latencies are high. There are 2 valid settings for this parameter:
"Enable" - The adapter will wait for all of a packet to be copied
from system memory to adapter memory before transmitting.
"Disable" - The adapter will start transmitting packets onto the
network before all data has been copied onto it from system
memory. It will begin transmitting once the number of bytes
copied equals the number set through the Transmit Threshold
parameter.
Transmit Threshold:
If the Store and Forward parameter is set to Disable, this parameter
indicates the number of bytes that must be copied from system
memory to adapter memory before the adapter starts transmitting
it. The first number of each selection is the value used when
running at 10 Mbps, the second is the value used when at 100 Mbps.
The lower the number, the greter the likelyhood is that transmit
error may occur when PCI bus latencies are high. The following
are the valid settings:
"72/128"
"96/256"
"128/512"
"160/1024"
** Please note, the Fast EtherWORKS PCI 10/100 driver
implements an algorithm which automatically increments the
Transmit Threshold if transmit errors occur due to high
PCI bus latencies. **

Troubleshooting
******************************************************************
If the adapter is not detected after running EZWORKS, installing
the adapter, and rebooting Windows 95, check the following:
1. Double click on My Computer/Control Panel/System to display
the System Properties Page.
2. Select the Device Manager tab from the System properties page
in order to view the list of devices in the PC.
3. Check in the list of devices for an entry labeled Other Devices.
If an Other Devices entry exists, double click on it to display
the list of devices under it.
4. Check the list for an entry labeled PCI Ethernet Controller.
If this exists, select/highlight it by clicking on it and
then click on the Remove button at the bottom of the page to
delete it.
5. Reboot the PC and the adapter should now be detected.
Should the Windows 95 driver detect an error while loading, an
error message will be generated and placed in the file called
NDISLOG.TXT in the Windows directory. Using any text editor,
look at the message. Any messages generated by the adapter driver
will begin with:
"Fast EtherWORKS PCI 10/100 Adapter (000X). Error Code="
This will be followed by three numbers all beginning with "0x".
The following is a table summarizing the meaning of the last of
the three numbers. If you are unable to rectify the problem,
please have the numbers available when contacting technical
support.
