Enhanced Reference Diskette for Personal Computers

      Described is a hardware implementation for enhancing the
reference diskette as used in PS/2* Systems.  A four phase
enhancement plan is outlined so that a single reference diskette (RD)
package will provide all the required configuration and test
functions required for PS/2 systems.

      Typically, RDs contain the software required to configure and
to test a family of PC products.  The RDs may also contain the
initial microcode load (IML) files that are shipped on systems that
have a system partition.  In prior art, this required many RDs to
support all PS/2 Systems.

      The concept described herein is designed to follow a phased
implementation to achieve the goal of a single RD package that will
support all PS/2 Systems.  The plan involves splitting the current RD
into two separate diskettes, promoting common code and to re-use the
common code within the software and to provide multiple system
support with each package until the goal is met.  The four phases of
implementation are as follows:

o   First phase - Restructure to multiple diskettes - This phase
    involves splitting the RD into two separate diskettes in order to
    regain space.  The first diskette is called the base RD (BRD);
    the second diskette is a diagnostic diskette (DD).  The two
    diskettes are referred to as the reference package.  The BRD is
    bootable and contains a) disk operating system (DOS) hidden
    files; b) tag file hidden, c) COMMAND.COM module; and d) all
    utilities except diagnostic related utilities; and e) IML
    image(s).  The DD is a non-bootable diskette.  The tag file on
    this diskette will indicate to the BRD that these two diskettes
    are part of one package, i.e., this DD will be used in
    conjunction with the BRD.  The DD contains a tag file (hidden); a
    diagnostic control program (DCP); all diagnostic modules and
    diagnostic utilities.

    Support for extra diskettes outside of the reference package.  -
    The RD multiple diskette support allows a servicer to use extra
    diskettes that contain configuration and diagnostic modules.
    This phase is provided to address servicer space on the RD.  The
    configuration program on the BRD asks the user to insert the
    diskette which contains the configuration file for any installed
    adapter that does not have a corresponding option file on the
    BRD.  The program will then read that file from that diskette.
    The DCP provides a similar hook in the advanced service mode of
    operation.  This phase allows the servicer to group multiple
    option files onto one diskette to be used in conjunction with the
    reference package.

o   Second Phase - Support split RD over the network - This phase
    provides for rudimentary networking support.  The goal is to
    eventually satisfy supporting all...
