Windows Err Msg: Problem With Disk Drive C (with Bus Mouse) (68806)


The information in this article applies to:

  • Microsoft Windows 3.0
  • Microsoft Windows 3.0a
This article was previously published under Q68806

SYMPTOMS

When you install Microsoft Windows version 3.0 on a system with a bus mouse, you may get the following message:
Problem with disk drive C: Please check that the diskette is properly inserted in the disk drive and the door is closed.

CAUSE

A hardware interrupt conflict with the hard disk controller and a bus mouse set to IRQ2 can cause this message. Many AT and 386 computers use interrupt 2 (IRQ2) to communicate with the hard disk drive. If your mouse hardware is also on this interrupt, you may have interrupt conflicts. Some examples of mouse hardware that can cause interrupt conflicts are as follows:
  • A bus mouse card set for IRQ2
  • A built-in mouse port on the motherboard that is configured for IRQ2
  • A video card with a built-in mouse port that is configured for IRQ2 such as the ATI VIP VGA

RESOLUTION

The solution is to reassign the mouse to an unused interrupt. Do this by resetting the jumpers on the bus card, or by using the software setup program for the mouse. The owner's manual of the hardware causing the problem should list the proper steps to change the IRQ.
