The NEC Prospeed 386 Laptop may stop responding (hang) during Microsoft Windows setup if a math coprocessor is installed and the jumper to the left of the math coprocessor is set incorrectly.
The jumper has three pins. The default settings are pins 2 and 3. Windows requires that the jumper be set to pins 1 and 2. This has been confirmed by NEC technical support.
NEC Prospeed users should contact NEC technical support or their dealer for correct installation instructions.
If you are using the NEC Docking Station, then the regular AUTOEXEC.BAT and CONFIG.SYS files are ignored and files named AUTOEXEC.DS and CONFIG.DS are used. You also need to add /M:7 to the HIMEM.SYS line:
