SYMPTOMS
========

After you install Windows 95, you may see the following error message on a blue
screen the first time the computer restarts:

  Windows: A fatal error 0D has occurred at 0028:xxxxxxxx in VXD VMCPD(01) +
  000026B. The current application will be terminated.

If you press any key, you see the same error message. If you press CTRL+ALT+DEL
to restart the computer, the same error message occurs.

You can start Windows 95 using Safe mode.

CAUSE
=====

This problem can occur on computers using a Cyrix 486DLC processor and a Cyrix
FastMath coprocessor. Some computers with this processor and coprocessor are not
compatible with Windows 95.

RESOLUTION
==========

To work around this problem, disable support for the coprocessor in Windows 95.
To do so, follow these steps:

1. Restart your computer. When you see the "Starting Windows 95" message, press
  the F8 key, and then choose Safe Mode from the Startup menu.

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

3. Double-click the System icon.

4. On the Device Manager tab, double-click the System Devices branch.

5. Click Numeric Data Processor, and then click Properties.

6. On the Settings tab, click the "Never use the numeric data processor" check
  box to select it, and then click OK.

7. When you are prompted to restart your computer, do so.
