In the back of the chassis under the power switch is an 8-bit switch, the hardware configuration register.

The hardware configuration register setting has priority, and will override software configuration register settings if a conflict arises. The 16-bit software configuration register resides in nonvolatile memory. The hardware configuration register is an 8-bit mechanical switch located on the IGS backpanel.
Appendix A describes the IGS hardware and software configuration registers, the factory default settings of each, and the procedures for changing those settings.
