Operating System Change Utility for Remote IPL Workstations

       Users at Remote Initial Program Load (IPL) workstations
occasionally have a need to change the operating system sent to their
workstation.  For instance, a user at such a workstation that is
currently running OS/2* Operating System, may need to temporarily
switch to DOS.

      This utility allows a user at an OS/2 or DOS Remote IPL
workstation to change the programs that are sent to the workstation
the next time it is IPLed, including the operating system itself.  As
currently designed, the utility allows the user to select between two
operating systems, OS/2 and DOS.  Within the two operating systems,
the user can select various IPL records that determine specifically
the programs sent to the workstation the next time it is IPLed.  Once
the user re-IPLs the workstation after making a selection using the
utility, the new system configuration is sent to the workstation from
the server.  Once the user is done using the configuration, the
workstation is again re-IPLed and the original workstation programs
are downloaded to the workstation.  This allows the user to maintain
a 'normal' boot scenario, while the selections made through this
utility are secondary or 'alternate' scenarios. The utility is
logically comprised of two parts: server and workstation.  The server
and workstation portions of the program communicate through remote
named-pipes using the Netbios protocol.  The flow of the program is
documented below.
