|
|

//
|
|
// Following are explanations for the diInfoFlags word in DISPLAYINFO:
|
|
//
|
|
// 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
