Verify that the host computer contains at least a 135 watt power
supply. There are no jumpers to select.
If you are using a standard 20 megabyte drive, you may refer to the
Simplified Formatting Instructions after completing the hardware
installation procedures. If your drive is a non-standard drive (i.e.
20 megabyte drives with other than 4 heads/615 cylinders, or hard
disk drives with a formatted capacity greater than 20 megabytes) you
will need to refer to the Dynamic Formatting instructions after
completing the hardware installation procedure.
If you do not know your drive parameters, return to the Storage
Controller menu to access a listing of the most common drives and
their parameters which we have provided for your convenience. If
your drive is not listed, refer to your drive manual or contact the
manufacturer.
Now that you have verified BIOS and determined the drive parameters,
you are ready to install the controller and drive into your host
computer.
