Next, the installation program will probe your system and try to find a mouse. Some mice may be detected automatically; in this case, a dialog box is displayed showing the port on which the mouse was found. Press [Space] to continue. You may then be asked to give additional information, such as whether you have a two-button mouse, and would like it to emulate a three-button mouse. Make the appropriate selections, and continue to the next section.
If your mouse was not detected automatically, you will be asked to identify the type of mouse you have, and whether or not you have a two-button mouse and would like it to emulate a three-button model. Following this screen, you will be asked to identify the serial port to which your mouse is connected. Select the appropriate serial port, and press [Enter]. You can then continue to the next section.
If you wish to change your mouse configuration after you have booted your Red Hat Linux system, you may use the /usr/sbin/mouseconfig command.
