 2.5 (19-Mar-96)	Fixed a VESA mode scanning bug introduced in 2.4.
 2.6 (25-Mar-96)	Some VESA BIOS errors not reported -- it fixes error reports on
 		several cards with broken VESA code (e.g., ATI VGA).

+		- Hardware testing order slightly changed, tests based on ROM
+		  contents done as first.
+		- Added support for special Video7 mode switching functions
