    When configuring an Irwin floppy tape backup in the AST Power Station and
    using Irwin EZTAPE Software version 2.X or above, be sure to complete the

                   1.  Under Power Station Options in the Power Exec System
                       Setup, set the "Floppy Drive B" field to "360 KB 5.25".

         Step B:   Enable the software to recognize the secondary floppy
                   I/O address:

                   1.  Add the line "SET ALTFDC=P:370" to the Power Exec's
                       AUTOEXEC.BAT file.
