Known Issues ------------ Viper VLB: When starting Windows 95, a corrupted band is displayed. Viper VLB 2MB & Viper SE 2MB with BrookTree 485 DAC: Windows displays black screen when using 800x600x32bpp. Viper VLB 2MB & Viper SE 2MB with BrookTree 485 DAC: Random screen corruption in Adobe Illustrator 4.10. Viper VLB: When a driver option is selected under Weitek Power tab, the screen changes correctly, but when you select the screen does not change back to the previous settings. Viper VLB: Select Shutdown and restart. System hangs at the "Please Wait For System To Shut Down" screen. Windows 95 VDD bug: On VLB and some early PCI systems the BIOS setup needs to have Shadow BIOS for the VGA Adapter region (C0000~C7FFF) set to Write Protect, if available. This problem is noticeable if you open a DOS session Full-Screen then press to return to Windows and again to return to DOS Full-Screen. If the system then locks-up or gives a blue screen fatal-error message this means that the card's VGA BIOS has been overwritten and you must either enable Shadow Write Protect, or altogether disable Video ROM-BIOS Shadowing. This problem is caused by the Windows95 VDD and cannot be corrected in future drivers. ALL PCI: Color palette shift in Mech Warrior 2 (Pentium Processor Edition) when game starts. Known Limitations ----------------- Viper SE 2mb with BrookTree 485 DAC: No 24 bit color option. This is a limitation of the hardware. Issues Addressed and Features Added ----------------------------------- DirectDraw: The driver now provides hardware acceleration and support for Microsoft's Direct Draw API. Acceleration: Screen to Screen BitBlt's, Memory to Screen, Solid Brushs, Patterned Brushes, Quads and TextBlts are now supported and accelerated wherever possible. WeitekCPLX: The control panel has been extended to work with the new Microsoft DisplayCard Driver interface method.
