Module Name:

    config.c

Abstract:

    This file implements the windows 9x side configuration functionality of the upgrade project.
    This includes unattend behavior and command line options in addition to the normal set of
    configuration duties.

Author:

    Marc R. Whitten (marcw)

Revision History:

    ovidiut     14-Mar-2000 Added encrypted passwords support
    marcw       15-Oct-1998 Cleaned up unattend options.
    jimschm     23-Sep-1998 Removed operation code
    jimschm     01-May-1998 Removed MikeCo plugtemp.inf crap
    marcw       10-Dec-1997 Added UserPassword unattend setting.
    calinn      19-Nov-1997 Added g_Boot16, enables 16 bit environment boot option
    marcw       13-Nov-1997 Unattend settings changed to get closer to a final state.
    marcw       12-Aug-1997 We now respect setup's unattend flag.
    marcw       21-Jul-1997 Added FAIR flag.
    marcw       26-May-1997 Added lots and lots of comments.

BOOL
Cfg_InitializeUserOptions (
    VOID
    )

/*++

Routine Description:

    This routine is responsible for Initializing user configurable options for the win9xupg project.
    These options can come from either the command line or an unattend file.  This routine also saves
    the user options into the Win9xUpg.UserOptions section of the answer file.

    The heirarchy of user options is:
        (1) Command line parameters.
        (2) Unattend file parameters.
        (3) Default parameters.

    In other words, command line parameters have precedence above unattend file parameters which in
    turn have precedence over the default parameters.

    Since this function relies on the winnt32 supplied Unattend File and Command Line parameters,
    it must not be called until after winnt32 has filled in the necessary variables. In practice,
    this means that this function cannot be called until after the first time one of win9xupg's
    wizard pages is activated.

Arguments:

    None.

Return Value:

    TRUE if user options were successfully configured, FALSE otherwise.
