Mouse device requirements

If you need to add or change the mouse, you must use mouseadmin(1) to configure the mouse before it can be used.

Certain system requirements must be met for successful installation of the mouse driver package:

• The driver package is configured automatically to use an I/O (input/output) address range of 23c through 23f if the bus mouse is selected for installation. Installation will fail if this I/O address range is not free and available. Check your mouse manual to determine I/O range.

• The bus mouse controller board must be set for I/O addresses 23c through 23f and these addresses must not conflict with any other expansion boards present in your system. You can display the current device attributes for your system with the Device Configuration Utility, /sbin/dcu. This command enables you to read and write configuration parameters such as I/O addresses.

• To use a PS2-compatible/Keyboard mouse, your hardware needs a PS2/Keyboard mouse port. Check your hardware reference manual to be sure you have the necessary hardware support if you plan to use a PS2-compatible/Keyboard mouse. The driver package is configured automatically to use interrupt vector 12 if the PS2-compatible/Keyboard mouse is selected for installation. Installation will fail if this interrupt vector is not available.

• Have you installed a mouse with your computer? What type?

  If you install a mouse on your computer, it can be a serial mouse, a bus mouse or a PS2/Keyboard mouse. Please refer to the documentation supplied with your mouse to determine your mouse type.

• If a mouse is installed, how many buttons does it have?

  Check to see if your mouse has two buttons, or three buttons. The default is two buttons.

• If a bus mouse is installed, for which interrupt vector is it configured?

  An interrupt vector may also be referred to as an ``IRQ''. The default provided by the installation process will usually suffice, but you should refer to your mouse manual to check this value and change it from the default if necessary.

• If a serial mouse is installed, which port will it be plugged into?

  Many computers have two ports, which are typically labeled COM1 and COM2 or ``Serial A'' and ``Serial B''. On UnixWare systems these ports are referred to as tty00 and tty01, respectively. Be careful not to confuse a printer port, which is also included on most computers, with COM2.
