The ND-755xA will be distributed configured as "primary Master".
If your notebook`s device slot needs to be configured as “secondary“ master,
may errors occur as wrong identification (slave), slow speed (IDE1/ pio)
or finally no detection.

>The flashed jumpersetting is irreversible!

>You can update from Notebook if drive will be recognized or from a
desktop pc by using an "IDE“ to “JAE KX15-50ELD1L“ Adapter

>The updates are only via DOS possible, other operating systems won`t be supported.

>The updates change only device`s jumperconfiguration.
