 Welcome to sysinst, the NetBSD-4.99.59 system installation tool.  This
 menu-driven tool is designed to help you install NetBSD to a hard disk, or
 upgrade an existing NetBSD system, with a minimum of work.
 In the following menus type the reference letter (a, b, c, ...) to select an
 item, or type CTRL+N/CTRL+P to select the next/previous item.
 The arrow keys and Page-up/Page-down may also work.
 Activate the current selection from the menu by typing the enter key.
