SUMMARY
If you receive the message &quot;Drive not installed; Microsoft Mouse not found&quot; each time you start your computer, and your Microsoft Mouse does not work in any MS-DOS application, this indicates that when the Microsoft Mouse Driver searched your computer system for a Microsoft Mouse, it could not detect a Microsoft Mouse.

This problem could be caused by incorrect serial port configuration, interrupt conflicts or a defective mouse.



MORE INFORMATION
The following is a brief description of the configurations the Microsoft Mouse Driver requires to install. This information applies to all versions of the Microsoft Mouse for MS-DOS systems.

The industry standards for the configuration of serial ports are as follows:   Port    Address    Interrupt ---   -

COM1   03F8h      IRQ4 COM2   02F8h      IRQ3 COM3   03E8h      IRQ4 COM4   02E8h      IRQ3 NOTE: COM1 and COM3 share an interrupt, as do COM2 and COM4. Because of this, if there are two devices on COM ports that share an interrupt, there will be a conflict between the two. A typical example of this is having a modem on COM3 and trying to install a Microsoft Mouse on COM1. To resolve such a situation, keep the modem on COM1, IRQ4 and put the Microsoft Mouse on COM2, IRQ3, or vice versa.

The addresses of the COM ports are important to the Microsoft Mouse driver. For more information about finding these addresses, query on the following words in the Microsoft Knowledge Base:   mouse and com and port and address and debug To verify the interrupt used by each port, check the documentation for the computer (if the port is on the motherboard), the I/O card documentation (if the port is on a card), or run a diagnostic program. Most I/O cards will have jumpers or switches that allow you to change the configuration of the card. You will need to contact your machine manufacturer or your vendor for further information on how to change your port switch settings.

If your ports are configured correctly, take your Microsoft Mouse to another machine that has a working Microsoft Mouse on it. Turn off the machine, plug the first Microsoft Mouse in, turn the machine on, and see if the suspect Microsoft Mouse works. If it does, then there may be something wrong with the port on your machine. If it does not work, then there is probably something wrong with your Microsoft Mouse. If this is the case, you should call Microsoft Sales Information Center (MSIC) at (800) 426-9400 for information about how to get your Microsoft Mouse repaired.

NOTE: COM3 and COM4 are not supported by the Microsoft Mouse.
