Chips & Technologies, Inc. DR655xx Display Driver Package Release Notes for Windows 3.X ======================================================================= Revision: Version 1.3.5 , 6555X Release Date: July 18, 1997 ======================================================================= Sun July 13,1997 -by- Raluca Iovan(1), Mike Calyer(2) 1. Completed bug fix #410. The change described below actually fixed the problem / area beneath the cursor when cursor was forced to SW. However, when the cursor was dinamically changed from HW to SW (such as NTSC or interlaced modes), the cursor problem still exists. This fix is taking care of it. WGA.ASM - ResetHiResMode. 2. Fixed forced hardware/software cursor support with video BIOSs that return function 5F50h with DL[4] = 0 , drivers check for panning bit. CURSOR.ASM , CC_CHANGEDISPLAY. ======================================================================= Revision: Version 1.3.4 , 6555X Release Date: July 02, 1997 ======================================================================= 1. Bug fix #482 : 65555X , after booting windows from DOS with POPUP enabled , cursor disappears. The cause was the POPUP 55X cursor initialization code was not being called , instead 655545/548 POPUP cursor intailization code was called. 2. Bug fix #410 : Alt Tab in/from DOS FS corrupts area beneath the cursor when SW cursor modes (65555 and intermitent). WGA.ASM - In ResetHiResMode skip checking HW popup cursor and HW cursor in offscreen memory for SW cursor. The bug occured because the above code was redrawing the SW cursor when it was not needed. The area beneath the cursor was beeing messed up by the EraseTail_10 algorithm in that particular instance. ResetHiResMode is called when returining from DOS FS and is asyncronuous with the displayed screen. Sometimes, the EraseTail_10 (whithin DrawCursor) would not restore the proper save_screen for the SW cursor. ======================================================================= Revision: Version 1.3.3 , 6555X Release Date: June 27, 1997 ======================================================================= 1. Bug fix #447 : do a long dir (dir/s in the root directory) and switch FS<-> DOS box - Alt-Enter. The screen does not come back until the dir/s is finished.
