Note: You may need to edit WIN.INI, and remove the [DrawDib] section to allow Video for Windows to retest the new driver and optimize itself.

These drivers support 640x480, 800x600, 1024x768, 1152x900, and 1280x1024 256 32k 16M ==================== 640x480 1MB 1MB 2MB 800x600 1MB 1MB 2MB 1024x768 1MB 2MB -na- 1152x900 2MB -na- -na- 1280x1024 2MB -na- -na- This is a very unofficial release! These drivers have not yet receieved thorough application testing. They _have_ been 'smoke tested' w/ the DCT. Install using Win95 Display Properties/Settings/Change Driver/Have Disk... You still need a VIPER.INI file (created by VPRMODE) stored in c:\viper or another path pointed to by SET VIPERPATH= Test Matrix: (these tests were all done w/ the 5Apr version, later versions are just being tested on PCI versions, unless another VLB specific problem crops up)... board/mem/version Bios tested 256 32k 16M =========================================================== Viper PCI 2MB A7 3.10 x x x Viper PCI 2MB B2 3.10 x x x Viper VLB 2MB E4 3.13 x x x Viper VLB 2MB D3 2.04 x x x Viper VLB 2MB A7 1.12 x x x Known Problems: * At 16bpp (32k colors) or 32bpp (16M colors), stretched .AVI files are rather slow (many frames dropped). Also, at 32k and 16M colors, AVI files in "MS Video One" format perform poorly. * Color/Animated cursors are NOT supported. Sorry! * These drivers have not undergone much application compatibility testing yet. * Bitblt performance is only optimized for 256 color modes. * DO NOT TRY TO RUN THE OLD DIAMOND VIPER CONTROL PANEL! IT WILL GPF! it will be automatically removed by the installation once I figure out how to do this... * Do not try to use the DPMI Diamond power management application either, it won't work right. * 32k color color mode has some drawing problems (noteably, the copying files status display has a magenta background...) email bug reports to pierce@diamondmm.com Please check the above list before reporting problems, I know about these already... please specify the Viper board revision, bios version, color depth, win95 build and anything else that might be important.
