Module Name:
jnsetset.c
Abstract:
A firmware tool that allows the user to examine and
modify the Alpha/Jensen PROM data.
Author:
John DeRosa 31-July-1992.
This module, and the entire setup program, was based on the jzsetup
program written by David M. Robinson (davidro) of Microsoft, dated
9-Aug-1991.

Routine Description:
This routine gets a menu selection from the user.
Arguments:
Menu Supplies an array of pointers to menu character
strings.
Selections Supplies the number of menu selections.
DefaultChoice Supplies the current default choice.
MenuTitle Points to a string that is the name of this menu.
BottomExtraLine1, If non-NULL, points to strings that should be
BottomExtraLine2 printed out below the "use arrow keys to select" line.
AutobootValue If zero, do not do an autoboot countdown.
If nonzero, do an autoboot countdown with this value.
ShowTheTime If true, show the time.
Return Value:
Returns the value selected, -1 if the escape key was pressed.
