Symptoms

If your computer has more than 1.5 gigabytes (GB) of memory (RAM), the computer may reboot continuously when you try to start Windows Millennium Edition (Me) or Windows 98.

Or, when you try to install Windows Me or Windows 98 with more than 1.5 GB of RAM installed, Setup may stop responding (hang) or reboot continuously.

Cause

Windows Me and Windows 98 are not designed to handle more than 1 GB of RAM. More than 1 GB can lead to potential system instability.

Workaround

To work around this issue, add the following line to the [386enh] section of the System.ini file:
MaxPhysPage=40000
This limits the amount of physical RAM that Windows can access to 1 GB. To add this line, use the following steps:
  1. Use any text editor (such as Notepad) to open the System.ini file in the Windows folder.
  2. Add the following line in the [386Enh] section of the file:
    MaxPhysPage=40000
  3. Save the file, and then restart your computer.
