Adapters and Modes Supported ============================ The ATI drivers will run on the following boards: Graphics Ultra Graphics Vantage 8514 Ultra Graphics Ultra Pro Graphics Ultra Plus Supported resolutions are: {640x480, 800x600, 1024x768 [256 colors]} Graphics Ultra Graphics Vantage 8514 Ultra Supported resolutions are: {640x480, 800x600, 1024x768, 1280x1024 [256 colors]} Graphics Ultra Pro Graphics Ultra Plus IF you have 2M video mem and the aperture enabled: 640x480 32 bpp [16,777,216 colors] 640x480, 800x600, 1024x768 16 bpp [65,536 colors] The supported resolutions and pixel depths are conditional on there being enough memory on the card. The pixel depth is conditional on the DAC type on the display adapter (see misc tips below). If you choose a resolution that is not supported or your card has not been installed for, the miniport will substitute one that is. Installing the Driver ===================== Installing a Driver ------------------- + UnZIP the files provided and copy them to a blank, formatted floppy disk, or path on your hard disk. + Boot Win NT, Logon as Administrator and run Windows NT Setup. + Select (O)ptions, (C)hange System Settings, (D)isplay and scroll down to "Other (Requires a disk from a hardware manufacturer)" + Select desired resolution. + (Interim solution) Exit Setup and bring up a Command Window. + CD into %SYSTEMROOT%\system32\drivers + Rename vga.sys to vga.sav + Copy from floppy disk (or disk path) vga.sys + Reboot into desired mode ! Reporting Problems ================== + Check under Misc Tips before filing a bug. + Send in a bug just like you would for any other Win NT bug encountered. Include in this report which card, monitor, video mode, computer system (w/speed, ram) and setup option you are using. E.G : Card : ATI Ultra Monitor : NEC 4D Video Mode : 800x600x256 Computer System : Compaq Deskpro 386/20 (20MHz, 16M ram) Setup Option : ATI Ultra Accellerator 800x600, 256 colors Known Problems to be solved in a future release =============================================== + DOS/Brief 3.1 in EGA/VGA mode only works with 25 lines when in started in from a Command Window. It works in full screen. This problem is known and will be fixed in the following release of Win NT. + I/O Port conflict w/ UltraStor 24f driver. This will be fixed in the next release of Win NT. An interim solution is to use the VESA SVGA driver for those with this configuration. Misc Tips ========= ATI boards require a hardware install program (run under DOS via a floppy) that sets the monitor selections, refresh rate, etc. You should only have to use this if you are installing the card for the first time. Hardware setup is necessary for enabling the aperture for the 32bpp and 16bpp modes. ISA cards require 4M of aperture space below 16M. Local bus, EISA, and MicroChannel cards can have the aperture anywhere below 127M. Other special boxes can have their apertures above 127M. These special boxes usually have the chip on the mother board rather than a graphics adapter card. The hardware install program guides the user through the hardware configuration process and will only allow the user to configure the aperture to memory address supported. If it doesn't initialize properly for the selected mode ------------------------------------------------------- Please report this as a bug and include the following "blue screen" message displayed : "ATI : accelerator not found" "ATI video driver: Determining adapter configuration" "Unsupported video mode" or " x by y , n bits per pixel configured" ; "x by y, n bits per pixel substituted" "DAC does not support this mode" If you run setup and install for a high resolution mode, and upon booting Win NT, get 640x480 graphics - boot DOS and run the ATI DOS card install program to set the monitor parameters for a monitor that can handle high resolution graphics. Check the event log to see if the ati driver failed to load. It won't initialize properly on a machine w/ certain ---------------------------------------------------- SCSI adapters, fax and modem cards. ----------------------------------- We're looking into 3 cases of I/O port conflicts which cause the ATi NT driver to unload and result in booting in Standard VGA. If you run into this, file a bug and let us know. Be certain to include which adapters you have in your system and their configuration. Noticed blue screen changed to black with streaks while booting Win NT ---------------------------------------------------------------------- This is normal behavior while the Win NT ATI driver is querying the adapter.
