        Arco Product(s): AC-125

        Environment:     In PC's and PC XT machines

        Description:     When the customer runs FDISK, no drive present will
                         happen. The reason for this error is the system won't
                         let you excess port 170 - 17F.

        Solution:        To solve this problem you will have to use a different I/O
                         address from 320 - 327. Please contact Arco electronics
                         for a replacement.
