"Windows Protection Error" After Upgrading to Windows 98

ID: Q187212

The information in this article applies to:

Microsoft Windows 98

SYMPTOMS

After you upgrade Microsoft Windows 95 to Windows 98 and restart your computer, you may receive the following error message:

Windows Protection Error
You must restart your computer

Your computer may then turn off automatically.

CAUSE

This behavior can occur when all of the following conditions exist:

You have installed Windows 98 on a Toshiba Libretto 50CT, 70CT or 100CT computer.

Your computer has a standard port replicator.

You have a serial mouse attached to the standard port replicator.

The Windows 98 serial port driver (Serial.vxd) conflicts with Toshiba's power management driver (Pwrsave.vxd).

RESOLUTION

To resolve this issue, obtain the latest power management drivers for your computer from Toshiba's Web site. These drivers are available as L50pwsave.exe, L70pwsave.exe, and L100pwsave.exe.

To work around this issue, follow these steps:

Restart your computer, press and hold the CTRL key until you see the Windows 98 Startup menu, and then choose Safe Mode Command Prompt Only.

Use any text editor (such as Edit.com) to open the System.ini file in the Windows folder.

Locate the "device=pwrsave.vxd" line in the [386enh] section of the System.ini file, and then disable it by placing a semicolon (;) at the beginning of the line.

Save and then close the System.ini file.

Restart your computer.
