1. A process of configuring a computer system having an internal port, and at least one external port, said ports having internal control registers wherein said control registers store information indicative of the designation of the corresponding port as primary, secondary, or disabled, and a non-volatile memory for storing a user's designation of each of said ports as either primary, secondary, or disabled, comprising the steps of: a) disabling said internal port; b) determining whether any of said at least one external ports has been designated as primary in its corresponding control register; c) setting said internal port control register designation to be primary, if the determination of step (b) is negative; d) determining if said non-volatile memory contains information indicative of said internal port being designated as primary, said process being complete if the determination of step (d) is affirmative; e) setting said non-volatile memory to contain information indicative of said internal port being designated as primary if the determination of step (d) is negative, said process being complete after the setting of step (e); f) determining whether any of said at least one external ports has been designated as secondary in its corresponding control register if the determination of step (b) is affirmative; g) setting said internal port control register designation to be secondary, if the determination of step (f) is negative; h) determining if said non-volatile memory contains information indicative of said internal port being designated as secondary, said process being complete if the determination of step (h) is affirmative; i) setting said non-volatile memory to contain information indicative of said internal port being designated as secondary if the determination of step (h) is negative, said process being complete after the setting of step (i); j) disabling said internal port if the determination of step (f) is affirmative; k) determining if said non-volatile memory contains information indicative of said internal port being designated as disabled, said process being complete if the determination of step (k) is affirmative; and l) setting said non-volatile memory to contain information indicative of said internal port being designated as disabled if the determination of step (k) is negative, said process being complete after the setting of step (l).
