Remote Software Installation Protocol

       A method for performing remote installation of microcode
and operating system programming is disclosed.  The method uses an
intelligent input/output processor to install microcode and operating
system microcode from an arbitrary source using a simple install
instruction followed by an optional install script.

                            (Image Omitted)

      The install process operates as follows:
1.  The source system (containing the microcode and operating system
to be installed) contacts the target system according to the protocol
(dial up, etc.).  This protocol may be a remote communications
method, direct attachment of storage media, or a combination of
these.
2.  The IOP on the target system establishes a communication link and
answers back with its unique identifier.  This identifier may be
encrypted.
3.  The source sends the target a request record containing the
following:
      a.  Function to perform:
           1)  Install to permanent storage on the target system
replacing the code resident on the system.
           2)  Install to temporary storage on the target system
(volatile execution memory).
           3)  IPL the target system without performing an
installation of code.  The IPL source may be either disk or removable
media attached to the target system.
      b.  Data records containing the initial loader program for
performing the installation.
4.  The IOP then transfers the data sent from the source system and
the install identifier to executable memory in the main processor.
5.  When the data transfer is complete, the IOP initiates an IPL of
the target system.  The IOP ca...
