1. What if the card is not found?
2. What if the driver is not found?
3. What if there is an IRQ Conflict?
4. What if files are not found?
5. What if windows Protection Error (95A/ 950)?
6. What if PC Locks Up?

This is normally caused by a resource (IRQ) conflict.

1. Verify that the card is firmly in the slot and seated properly.
2. Verify that the PCI slot is working properly.
3. Run the diagnostic to verify the card is working properly. Refer to IRQ Conflict steps 2 through 4 and choose Adapter Diagnostics.
4. Check in the Device Manager under Network Adapters to see if the card installed itself. If it did, write down the IRQ and I/O address the card is using.
5. Remove the driver and turn the computer off.
6. Physically remove the adapter from the motherboard and restart the computer.
7. Go to Device Manager and click on Computer.
8. If another device is using the same IRQ, you have an IRQ conflict. Refer to the IRQ conflict section for instructions on what to do.

When loading the driver, type in the path A:\ or A:\Win95 with the driver disk in Drive A. If neither of these directories work you may be having an IRQ conflict.

Relocate the DFE-530TX card to a different PCI slot, thereby, providing Windows with an opportunity to reassign the network adapter card a different IRQ.

Note: The BIOS in some computers allows you to disable the Plug-and Play feature for a particular PCI slot. This, in turn, allows you to select the IRQ and I/O address for the network adapter card. Please contact your PC's hardware manufacturer for directions on how to do this.

Point to:
C:\windows
C:\windows\system
C:\windows\help
Check Window 95/98 CD and look under \Win95 or \Win98 directory.

This is caused by an older driver problem.

Unfortunately, the DFE-530TX cannot work under the NDIS 4.0 driver in Win95 (950 and 95A)

Based on the Microsoft specification, the Win95 (950 and (95A) requires the NDIS 3.0 driver. Windows 95 OSR2 and Windows 98 require the NDIS 4.0 driver.

Follow the following steps to fix this bug:

1. Remove the DFE-530TX adapter in Network Configuration.
2. Delete the NETDLFET.INF file in the \WINDOWS\INF directory.
3. Delete the DLDFET.SYS fiel in the \WINDOWS\SYSTEM directory.
4. Restart the computer and allow Windows 95 to autdetect the DFE-530TX. If using Win950 or Win95A, poin to the Netdlfet.inf file inside the Win95 folder on the driver diskette. If using Win95B or Win98, point to the Netdlfet.inf file on the root of the driver diskette.
5. Provide the Win95 or Win98 CD and make sure that all files are found on the CD or driver diskette.
6. Before restarting, check in Device Manager under Network Adapters that the DFE-530TX is using the available resources and check that the Network Configuration has the corrrect clients, protocols, and file and printer sharing.

This is caused by an IRQ conflict.

Follow these steps to resolve the conflict:

1. Change slots. Different slots use different IRQs.
2. Verify there is a free IRQ in Device Manager.
3. If there are no free IRQs it is necessary to free up an IRQ by removing something. You must find a device that is not needed or is no longer in use. For example, an extra or unused LPT port or USB Controller. In either case you must get into the BIOS and disable the device. These two can usually be found in the Integrated Peripherals selection. Find the device and set it to DISABLE. Once this has been done Save and Exit. Once you have booted back up into Windows be sure the disabled device has been removed. If not, remove it. This should give you a free IRQ.

Step 1: Select Adapter Menu
Verify the adapter is using a free IRQ. Verify the NODE ID starts with 00 80 C* ** ** ** and press Enter.

Step 2: Choose Adapter Basic Diagnostic
In the Items Setup Menu, make sure there is an 'X' in: NIC Register Test, MII Register Test and EEPROM Test.

Step 3: Press Enter and verify it passes all tests
If the adapter fails any portion it is considered a bad adapter and should be replaced. If the adapter passes, there may be a problem with the Windows Operating system. Reinstall Windows or Install a DE-220PCT adapter and restart the computer.
