Disk Support Device for Diskless Personal Computers

      Described is a software implementation which allows a diskless
Personal Computer (PC) to be logically connected to external devices
utilizing an internal infrared receiver/transmitter.  The software
controls the infrared communications used to send disk Input/Output
(I/O) requests to a remote station.

      The technique is used primarily in environments which could
damage disks and disk drives by providing a means where the PC is
completely transparent.  It provides compatible operating system
application access to a remote station, as would a standard PC.

      In actual operation, the remote station receives and interprets
the request sent by the diskless PC and sends the requested data and
status information to the diskless PC by way of the infrared medium.
The technique allows the creation of unique PC operations which are
impervious to harsh environments, such as high humidity, exposure to
chemicals, excessive vibration, and others, such as where contact
corrosion is a problems when contacts that handle low currents are
used in communications adapters.

      The Fig. 1 shows a block diagram of how the concept is
implemented through appropriate algorithms.  The algorithms provide
the controls for the disk support device when interfacing the PC with
the application programs and with the basic input output system
(BIOS) and a remote disk.
