EISA Bus Computer Detects Display Adapter Incorrectly

ID: Q133726

The information in this article applies to:
  • Microsoft Windows 95

SYMPTOMS

After you set up Windows 95 on a computer with an EISA bus, the display adapter may not function correctly. You may receive the following error message:

There is a problem with your display adapter. The hardware settings are incorrect, or the current settings do not work with your hardware.
In Device Manager, there may be an exclamation point in a yellow circle next to the display adapter, with the following status in the adapter's properties:
Device Failure: Try changing the driver for this device. If that doesn't work, see your hardware documentation. (Code 27)"
You may also notice that the display adapter driver is not the correct type. For example, you may notice that Windows 95 has installed the Cirrus Logic 5422 display adapter even though you actually have an ATI Mach32 display adapter.


CAUSE

The EISA configuration in the EISA BIOS for the display adapter is configured for a device other than the one installed.


RESOLUTION

Use the computer's EISA configuration tool to reconfigure the slot for the correct display adapter type, and then run the Add New Hardware Wizard to redetect the display adapter. To redetect the display adapter, follow these steps:

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


  2. Double-click the System icon.


  3. On the Device Manager tab, click the incorrect display adapter, and then click Remove.


  4. When you are prompted to restart your computer, click No, and then click Close.


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


  6. Double-click the Add New Hardware icon, and then click Next.


  7. When you are prompted "Do you want Windows to search for your new hardware?" click Yes, and then click Next.


  8. Click Next.



MORE INFORMATION

Some computers with an EISA bus have a utility for configuring the expansion slots in the computer for a specific device. Replacing the device in a particular slot may lead to unexpected behavior from the computer and from Windows 95.
