Intel® PRO/100 ISA Adapter
Windows NT* 4.x Installation Notes

Location of Driver:   \NT\E100ISA.SYS
  \OEMSETNT.INF

General Installation:

  1. Open the "My Computer" icon.

  2. Open the "Control Panel" icon from the My Computer window.

  3. Open the "Network" icon from the Control Panel window.

  4. Select the "Adapter" tab

  5. <Optional> If you're replacing a previously installed LAN adapter, select the old adapter and click "Remove".

  6. From the "Adapter" tab, click "Add".

  7. From the Select Network Adapters window, click "Have Disk".

  8. From the Insert Disk window, insert the EtherExpress™ PRO/100 ISA LAN Driver disk into drive A: and specify the path as A:\, click "OK"

  9. From the Select OEM Option window, select "Intel PRO/100 ISA" from the list of models and click "OK".

  10. If more than one PRO/100 ISA is installed in your system, specify the Serial Number of the adapter you are installing. If there is only one PRO/100 ISA LAN adapter installed in your system just click "OK".

  11. The Network window then shows a list of the installed LAN adapters. Click "Close"

  12. From the Network Window, click the "Identification" tab, enter a unique computer name and the name of your new or existing workgroup, then click "OK"

  13. When Windows NT finishes copying files and updating the network configuration, and you are prompted to restart your computer for the changes to take effect, click "Yes".

Troubleshooting Tips:

At Least One Device Or Driver Failed During System Startup

If Windows NT fails to detect or initialize the PRO/100 ISA adapter, you will get this error message in the Event Viewer:

"At least one service or driver failed during system startup. Use Event
Viewer to examine the event log for details."

If this error is related to the PRO/100 ISA LAN Adapter, you should see an entry in the Event Viewer in the source column labeled "E100". Double click on that entry and view the error message.

  1. Verify that the I/O address and/or interrupt being used by the PRO/100 ISA are not being used by any other device in your workstation like a sound card, faxmodem, scanner, tape backup, serial ports, parallel ports, etc.

  2. Verify that the PRO/100 ISA passes all diagnostic tests by running CONFIG.EXE from DOS and selecting "DIAG". If the EtherExpress PRO/100 ISA adapter fails diagnostics it will not function correctly under Windows NT. If diagnostics fail, try setting the EtherExpress PRO/100 ISA to a different I/O address or a different interrupt.

Adapter Passes Diagnostics But Still Does Not Work With Windows NT

If the adapter passes diagnostics but still does not work with Windows NT, there could be a problem with the network setup configuration. If you've made several attempts to configure the network setup for Windows NT or had another adapter installed before the EtherExpress PRO/100 ISA adapter, it may be necessary to restore the Windows NT network configuration to default settings and then reconfigure the Windows NT network setup. Here's how:

  1. Open the "My Computer" icon.

  2. Open the "Control Panel" icon from the My Computer window.

  3. Open the "Network" icon from the Control Panel window.

  4. Select the "Adapter" tab

  5. Select the "Intel PRO/100 ISA" from the Network Components list, and click "Remove". This removes the adapter and all associated components from the Windows NT network configuration.

  6. From the Network Configuration window, click "OK".

  7. When Windows NT finishes copying files and updating the network configuration, you will be prompted to restart your computer for the changes to take effect, click "Yes".

  8. After the workstation reboots, continue at step 1 of the GENERAL INSTALLATION section of this document.

Using E100ISA Driver Keyword Options:

Use32BitIO
NO, YES
Selects whether 32 bit i/o instruction is to be used for the transfer of data from the adapter to memory. Some machines garble data when 32 bit i/o is performed. The default parameter is NO.

MEDIATYPE
AUTO, HALF10, FULL10, HALF100, FULL100
Selects the speed and duplex characteristics at which the adapter will attempt to connect to the LAN.

Serial
The last 6 digits of ethernet MAC address
Selects which adapter (when more than one adapter exists). "hhhhhh" is the last 6 digits of the IEEE address assigned to the adapter. This number can be obtained from the configuration program, or from the bar code sticker on the adapter.

TxQueue
1 - 16
The TXQUEUE keyword is used to adjust the size of the transmit queue. The default transmit queue is 3 entries.

RXBurstCount
0 - 15
Receive hysteresis is used to reduce the number of receive interrupts caused by an adapter. A receive interrupt occurs when either "n" packets are received or timer "t" expires (the time-out is measured in microseconds). RXBurstCount sets the "n" value in this example. Increasing this value will slow down the adapter, but it will also reduce the CPU utilization.

RxBurstTimeout
0 - 6550
Receive hysteresis is used to reduce the number of receive interrupts caused by an adapter. A receive interrupt occurs when either "n" packets are received or timer "t" expires (the time-out is measured in microseconds). RXBurstTimeout sets the "t" value in this example. Increasing this value will slow down the adapter, but it will also reduce the CPU utilization.

RxEarly
OFF, ON
The RXEARLY keyword is used to disable the pipelined processing of receive packets. By default, pipelined processing (Early Receives) is disabled. Pipelined processing improves your performance by reducing receive latency (the time it takes for a receive packet to get from the media to your PC's memory), but increases the CPU overhead incurred by the driver. Disabling pipelined processing INCREASES receive latency and hinders performance but adds greater compatibility.

LinkIntegrity
ON, OFF
Selects whether valid link information is to be transmitted by the adapter. Some older hubs do not support the transmission of valid link information. The default parameter is ON.

NetworkAddress
12 digit hexidecimal address (LAA)
Any legal Ethernet value that will override adapter's unique Ethernet hardware
address. This parameter is used by the NDIS3 drivers only
