Displaying Planar-Defined Messages on Personal Computers

      Described is a software implementation that provides a method
of displaying planar Adapter Description Program (ADP) defined
messages during setup operations, as used in Personal Computers
(PCs).  The messages relate to the memory configuration process and
are intended to enhance the PC usability during the setup operations.

      In prior art, the use of planar ADP programs provided a means
of detecting memory errors and to provide the proper memory
configuration.  However, there was no method of notifying the user of
the details of the configuration errors.  Additionally, memory
configuring the ADP programs may not have enabled all the memory in
the system if the memory diagnostics had previously disabled a
particular memory.

      The concept described herein provides a means of displaying to
the user an error the first time it is detected.  A new Setup
Services (SS) sub-function is added to the current list of
sub-functions within the ADP which can call on the setup operation to
display a message as defined by the ADP itself.  The same text
structures, within the ADP, are used in the setup program so that
only the interface between the setup and the ADPs need be modified to
provide this new sub-function.

      The SS function is invoked by the ADP issuing a Resource Query
(RQ) call to the setup program with the RQ parameter block
initialized with an '08h' in the function byte.  Whenever SS is
invoked, the sub-function desired by the ADP is designated within the
'SS subfctn' byte.  The new sub-function, called ADP Message Display,
is designated by a 05h in the 'SS subfctn' byte of the parameter
block.  Table 1 shows the structure of the RQ parameter block as
defined with the SS support.

      Three types of message windows are made available to the ADP:
Informational; Warning; and Error.  To specify a particular window
type, the ADP initializes the 'SS_Res_Parm' byte of the RQ parameter
block with the type number corresponding to the window type desired.

The Informational window is designated with a value of 01, the
Warning window is designated...
