module of code and performs a presence test for the device supported by
each device module.

fixed disk drive.
Note:
Some devices have their own stand-alone diagnostic diskette.
The device must be installed or attached.
The device must return a 'ready' acknowledgment value to the DCP.
If these conditions are met, the DCP loads that module into memory, adds
the device name to the Installed Devices list, and continues with the next
module.
These steps are repeated until the DCP has performed a presence
test for each module on the fixed disk drive..
tests have been performed, the DCP displays the Installed Devices list.
