The FreeBSD-3.0 binary distribution is ELF only. The display manager makes your PC look like an X terminal. The XF86Config file tells the X server what kind of monitor, video card and mouse you have. You must create it to tell the server what specific hardware you have. The interface type can be determined by looking at the connector of the mouse.
Some mice come with adapters with which the connector can be converted to another.
There may be more than one serial port to which the serial mouse can be attached. Error messages are lost unless you redirect them because the server takes over the screen. You can cus- tomize your X by creating .xinitrc, .xserverrc, and .twmrc files in your home directory as described in the xinit and startx man pages. For a general description of BSD kernel configuration get smm.02.config.ps.Z . The generic FreeBSD kernels are configured by default with the syscons driver.
