; Notes
|
||
;---------------------------------------------------------------------
|
||
; In an effort to keep things simple (yet eliminate the use of BoxFlag),
|
||
; the VideoInfo data structure has been modified to contain two new
|
||
; fields. One of these fields contains the particular sRsrc directory
|
||
; directory (or Super sRsrc directory) to select. However, some CPUs
|
||
; don’t have built-in video (e.g., the IIfx), so, by definition, those
|
||
; CPUs should be placed into the BoxFlag-based sRsrc directory. The other
|
||
; field is a “way out” in cases where BoxFlag is necessary -- i.e., it
|
||
; contains the BoardSRsrcID. For CPUs that fall into the BoxFlag-based
|
||
; sRsrc directory, this field is just zero, indicating that the
|
||
; board sRsrc is a derivative of BoxFlag. Where the BoardSRsrcID
|
||
; field of VideoInfo is non-zero, this is the board sRsrc ID of
|
||
; particular family of CPUs using the same video controller.
