As a specific example, suppose the system we re using has SWTPc's S-BUG installed and we wish to run FLEX. The first step is to power on all equipment and make sure the S-BUG prompt is present (>). Next insert the system diskette into drive 0 (the boot must be performed with the disk in drive 0) and close the door on the drive. Type "D" on the terminal if using a full size floppy system or "U" if a minifloppy system. The disk motors should start, and after about 2 seconds, the following should be displayed on the terminal:
FLEX X.XThe name FLEX identifies the operating system and the X.X will be the version number of the operating system. At this time the current date should be entered, such as 7,3,79. The FLEX prompt is the three plus signs (+++), and will always be present when the system is ready to accept an operator command. The '+++' should become a familiar sight and signifies that FLEX is ready to work for you!
