System switches
Various system function options are selected with Switch 2.
The “S” switch selects whether the card boots from user defined parameters
(defined in the Setup Programs chapter), or the BIOS defaults. Setting this switch
Off allows the user to return to factory programmed defaults.
The “X” switch is reserved for future use.
The “V” switch enables or disables the on-card video, allowing an external video
card, or the serial console to be used.
The “U” switches are user defined and can be used for program control.

System switch
The system switch is position 1. When this switch is On the system boots using the
parameters stored in Setup. When this switch is Off the system boots using the
factory defaults for all parameters in Setup. Note that if you must set the system
switch Off to recover your system, the user-defined parameters in Setup will not be
changed unless you enter Setup, make the changes, and exit saving changes.
Video switch
The video switch is position 3. When this switch is On the on-card video is enabled.
To use a serial console, or an extension-card video only without using the onboard
video controller (such as a PC/104), set this switch Off.
