           POWER STATION FLOPPY DISK AND NON-DOS OPERATING SYSTEMS


When the Power Exec is connected to the Power Station and running under
certain non-DOS operating systems, the second drive option will not function.

The Power Station uses secondary  I/O addresses for the floppy controller
that supports the second floppy drive.  Non-DOS operating systems such as,
IBM OS/2.1 and SCO ODT r2.0.0 do not have support for secondary I/O addresses
for the floppy controller and will not support the Power Exec's second floppy
drive option
