A BIOS-based program that allows you to configure your system's hardware and customize the system's operation by setting such features as password
protection and energy management. Some options in the System Setup program require that you reboot the system (or the system may reboot automatically)
in order to make a hardware configuration change. Because the System Setup program is stored in NVRAM, any settings remain in effect until you change them
again.
system.ini file
A start-up file for the Windows operating system. When you start Windows, it consults the system.ini file to determine a variety of options for the Windows
operating environment. Among other things, the system.ini file records which video, mouse, and keyboard drivers are installed for Windows.
Running the Control Panel or Windows Setup program may change options in the system.ini file. On other occasions, you may need to change or add options
to the system.ini file manually with a text editor, such as Notepad.

devices are connected in a series, you may need to enable or disable the termination on these devices by changing jumper or switch settings on the devices
or by changing settings in the configuration software for the devices.
