If there is a diskette in the drive, verify that:
– There is nothing wrong with the diskette. Try a backup copy if you have
one.
– The diskette is inserted correctly (label up and metal-shutter end first) in
the diskette drive.
– The diskette contains the necessary files to start the system.
– There is nothing wrong with your application program (see page 215).
If the preceding items are correct, have the computer serviced.
If there is no diskette in the drive, have the computer serviced.
It is probably because Mwave is being used for other functions, such as the
modem. Try disabling another function; then type MWGAMES ON MIN. The
MIN option will enable Sound Blaster support using the minimum possible
amount of Mwave resources.
Some DOS games run slower in a Windows DOS session than in native DOS.
Check the documentation of your game for special instructions about improving
performance. Configure Windows to use the VGA display driver rather than a
higher resolution or less efficient driver. Determine if your game allows you to
turn off "background music" and only play special effects.
Verify that:
The modem/fax port is securely installed.
The modem is correctly identified in your communication program.
This is often caused by a conflict of the communication port address or
interrupt assignments or both.
This is often because of the DSP resources have been used up. Try stopping
some application that is using the DSP, and retrying the failing function.

Refer to the command reference in the Mwave ThinkPad window.
Verify that you have started your modem. Make sure you did not close it
instead of minimizing it. Verify that it was set to support the speed you are
trying to use.
Verify that you disabled the Audio button in the Audio Control.
