Disabled Net Card on Compaq XL560 Is Detected By Plug and Play

• Microsoft Windows 95

SYMPTOMS

The Compaq XL560 EISA PCI-based and DeskPro 5100 computers have a built-in AMD Ethernet network interface card. When the internal network card is disabled through CMOS and a second network card is installed, Windows 95 detects both the internal and the secondary network cards during the Plug and Play detection portion of Setup.

CAUSE

The built-in network interface card is disabled from a system BIOS point of view only--Windows 95 recognizes it as an unconfigured device. Windows 95 treats unconfigured devices as PCMCIA devices and assigns them IRQ 9 and an I/O range. As a result, the device is recognized in the Plug and Play detection phase.

RESOLUTION

To correct this problem, disable the built-in network interface card through the Device Manager in Control Panel.

To disable the internal network card in Windows 95, perform the following steps:

1. Click the Start button, point to Settings, and then click Control Panel.

2. Double-click the System icon.

3. Click the Device Manager tab.

4. Click the plus sign next to Network Adapters.

5. Click the AMD network interface card, then click the Properties button.

6. Under Device Usage, change the status by clicking the option that reads "Original Configuration"

7. Click the OK button to accept the change, then close Device Manager and Control Panel.
