// RETURNED_DATA_IS_STALE, if set, means that this call to VDD_GET_DISPLAY_CONFIG
// or VDD_GetDisplayInfo (which are the Ring 3 and Ring 0 methods by which a
// program would get the DISPLAYINFO structure returned to him) caused the VDD
// to return data that was read in a previous call to VDD_GET_DISPLAY_CONFIG
// insted of actually going out and reading "fresh" data from the Registry.
//
// This flag brings to light the fact that there are some circumstances when the
// VDD cannot go out and read the registry in response to the call to
// VDD_GET_DISPLAY_CONFIG or VDD_GetDisplayInfo (due to system multi-tasking
// considerations). In this case, this flag will be set to a 1 to indicate that
// the information being returned isn't "fresh" -- that is -- it may be
// incorrect and obsolete. The caller should respond accordingly if this flag
// is set.
//
//
// MINIVDD_FAILED_TO_LOAD if set, indicates that for some reason (typically
// that the MiniVDD didn't match the chipset installed in the machine), the
// MiniVDD didn't load. Callers can examine this flag and act accordingly.
//
//
// MINIVDD_CHIP_ID_DIDNT_MATCH means that although the MiniVDD did load
// successfully, when the ChipID that the MiniVDD calculated was compared
// against the value saved in the registry, they didn't match. An example of
// when this would happen is when the user is happily using an S3-911 card
// and then decides to upgrade his display card to an S3-864. Since both
// cards use S3.VXD, the MiniVDD will load, however, since the card model
// is different, the VDD will return a defect to configuration manager and
// set this flag. Callers of the GET_DISPLAY_CONFIG functions can use this
// flag to take appropriate actions to make sure that the user gets his
// configuration correct.
//
//
// REGISTRY_BPP_NOT_VALID if set, means that we failed to obtain the BPP value
// from the registry when the VDD tried to read it.
//
//
// REGISTRY_RESOLUTION_NOT_VALID if set, means that we failed to obtain the
// resolution value from the registry when the VDD tried to read it.
//
//
// REGISTRY_DPI_NOT_VALID if set, means that we failed to obtain the
// DPI value from the registry when the VDD tried to read it.
//
//
// MONITOR_DEVNODE_NOT_ACTIVE is set if someone tries to make a call to the
// GET_DISPLAY_CONFIG function before the monitor DevNode has been created.
// This is certainly not fatal by any means. It simply means that the
// monitor refresh rate info in the DISPLAYINFO data structure is totally
// invalid!
//
//
// MONITOR_INFO_NOT_VALID indicates that something within the code which
// retrieves and calculates the refresh rate data has failed. This indicates
// that the values in diRefreshRateMax through diVertSyncPolarity are not
// valid and could contain random data.
//
//
// MONITOR_INFO_DISABLED_BY_USER indicates that the either the RefreshRate=
// string in SYSTEM.INI had a negative number in it or that the string in
// the display's software key RefreshRate = string was 0 or a negative number.
//
//
// REFRESH_RATE_MAX_ONLY indicates that there was no diLowHorz, diHighHorz,
// diLowVert, diHighVert, or sync polarity data in the registry. The
// value returned in diRefreshRateMax is the only refresh rate data that
// we have available. This was derived either from RefreshRate= in SYSTEM.INI
// or the display software key RefreshRate = string in the registry.
//
//
// CARD_VDD_LOADED_OK indicates that a second MiniVDD (which is useful for
// display card manufacturers wishing to extend the capabilities of the chip level
// MiniVDD's ) has successfully been loaded and initialized.
//
// DEVICE_IS_NOT_VGA indicates that this device is not the primary vga
