OS/2 2.1 Power 9100 Display Drivers Version 1.10.10 BETA 11/11/94 Driver Features: ---------------- This driver supports the following features: 1) PCI/VL-Bus Auto Detection. 2) 8, 16 and 32 Bits Per Pixel. 3) IBM 525 RAMDAC support. 4) Brooktree 485 RAMDAC support. 5) Auto-Resolution correction based on display mode being requested and amount of VRAM available. 6) Auto Display Refresh Rate correction based on the capabilities of the RAMDAC on the installed adapter. For example, if 1600x1200 8 Bpp mode is selected on an adapter which uses a Bt485 RAMDAC 135MHz, the driver will not allow this mode to be set since the DAC does not support this mode. Instead, it will display a warning message. DO NOT try to install for this mode. It may damage your adapter. 7) OS/2 Windowed Sessions. 8) DOS Windowed Sessions. 9) Full screen OS/2 sessions. 10) Full screen Dos sessions. 11) Power 9100 Full screen Windows sessions. 12) Power 9100 Seamless Windows sessions. 13) Resolution and color depth switching without having to reinstall the drivers. 14) Configurable display refresh rates. 15) After the drivers have been installed and enabled by restarting the system, the configuration utility will display only the color depths and resolution modes supported by the installed adapter. 16) 1, 2 and 4 Megabyte VRAM support. Mode Support ------------ The following display resolution modes are supported by this driver: NOTE: Take into consideration the amount of memory on your video card. Some of the modes supplied are NOT supported if the card has only 2MB of video memory. 8bpp/256 col 16bpp/65k col 24bpp,32bpp/16.7M col 640x480 2/4MB 2/4MB 2/4MB 800x600 2/4MB 2/4MB 2/4MB 1024x768 2/4MB 2/4MB 4MB ONLY 1280x1024 2/4MB 4MB ONLY 4MB ONLY *1600x1200 2/4MB 4MB ONLY * - IBM DAC ONLY Driver Installation Procedures: ------------------------------ The diskette must have the correct volume label in order for the install program to function correctly. The correct volume label is: P91DRV 1 The space is required. You can apply the volume label to the disk by typing the following from an OS/2 command prompt: label x: [Enter] P91DRV 1 [Enter] Where x is the drive letter of the floppy drive containing the Power 9100 driver disk. For example, if the floppy drive with the Power 9100 driver disk was drive A, you would type: label a: [Enter] P91DRV 1 [Enter] Driver installation is initiated by running the INSTALL.CMD batch file from the installation diskette. This batch file copies installation files to the OS/2 installation directory and executes the OS/2 DSPINSTL program from the hard drive. The OS/2 driver installation program installs both the OS/2 drivers and the Windows drivers. Do not perform a separate installation of the Windows drivers as described in the Windows drivers release notes. To do so can cause problems; for example, Seamless Windows support may no longer work, and the version of Full Screen Windows drivers may not be compatible with Full Screen WIN-OS2. 1) Bring up OS/2 as you would normally. (VGA driver should be installed.) 2) Make sure you have closed any Windows Full Screen and Seamless Windows sessions. 3) Insert the Power 9100 OS/2 distribution diskette into either drive A: or drive B:. 4) Select either an OS/2 Window or OS/2 Full Screen session from the "Command Prompts" folder. 5) Select the diskette drive you are using by typing either A: or B: and [Enter]. 6) To start the installation, type install : Where is the letter of the drive where OS/2 is installed and started from. For example, if you have installed OS/2 on drive C: then you would issue the command install c: 7) In the "Display Driver Install" dialog box, select Primary Display and click on the OK button. 8) In the "Display Adapter Type" dialog box, select Power 9100 Display Driver and click on the OK button. 9) In the "Source Directory" dialog box, ensure that the drive indicated is the drive the installation diskette is in. Change it if necessary. Click on the Install button. The installation utility copies files into the appropriate directories and modifies the CONFIG.SYS, SYSTEM.INI, and OS2.INI files. 10) When the file have been copied, the Power 9100 Configuration Utility dialog box will be displayed. You may now select the specific driver configuration that you would like to run. You do this by making selections in the Monitor, Color Depth, Resolution, Refresh Rate and Resource Size list boxes. After you have specified the desired configuration, click on the Save button. The Power 9100 Configuration Utility saves the configuration information in the OS2.INI file. It also creates a "Weitek Display Driver Utilities" folder on the OS/2 desktop. This folder contains utilities for configuring the Power 9100 OS/2 display driver as well as the Power 9100 Full Screen Windows display driver. The Full Screen Windows drivers are installed using the default configuration of 640x480 8 bits per pixel configuration. Upon restarting OS/2 you may change this configuration by running the Power 9100 Full Screen Windows display driver configuration utility from the "Weitek Display Driver Utilities" folder. Note: Your hardware may not support all of the displayed color depths and resolutions. If you are unsure of whether a specific configuration is supported by your hardware, select cancel and the proceed to step 11. This will install the default configuration of 640x480 8 bits per pixel. Upon restarting OS/2, follow the procedures in the "Changing Power 9100 OS/2 Driver Configuration" section. 11) The "Display Driver Install" dialog box informs you that changes have been made to your system configuration and you must shut down your system. Click on the OK button. 12) Remove the distribution diskette from the diskette drive. 13) Shut down the system by selecting Shut Down from the OS/2 desktop menu. 14) Press Ctrl/Alt/Delete. 15) Restart OS/2. The selected driver configuration is now installed and running.

No files are deleted by the removal utility. 8) The "Display Driver Install" dialog box informs you that changes have been made to your system configuration and you must shut down your system. Click on the OK button. 9) Exit the OS/2 Window or Full Screen command prompt by typing, exit [Enter] 13) Remove the distribution diskette from the diskette drive. 14) Shut down the system by selecting Shut Down from the OS/2 desktop menu. 15) Press Ctrl/Alt/Delete. 16) Restart OS/2. OS/2 should now come up in VGA. Known Limitations ----------------- There are issues with OS/2 2.11 (OS/2 2.1 with OS/2 Corrective Services Diskettes XR06200), and 32-bits-per-pixel (32 bpp) modes. These issues will appear in OS/2 applications that display bitmaps, such as OS/2 Chess. In 32 bpp mode, the chess pieces will appear clear. You may also see black icons on the OS/2 desktop. These are issues with OS/2 2.11, as the problems do not appear with the retail copy of OS/2 2.1. Any issues in 32 bpp mode with OS/2 2.11 should be verified on OS/2 2.1 to determine if the problem is caused by OS/2 2.11 or the Power 9100 drivers. Multimedia Presentation Manager/2 (MMPM/2) has issues with 16 bpp modes that are corrected in the OS/2 Corrective Services Diskettes XR06200. It is recommended that the Corrective Services Diskettes for MMPM/2 be applied to resolve this problem. Multimedia Presentation Manager/2 (MMPM/2) currently does not support 32 bpp modes. During program load from the desktop, the colors of the icons on the desktop may change colors, or the entire screen may change colors. Some programs supply their own color palette which overrides OS/2's color palette. The desktop should return to normal when the application is closed, or by performing an action (such as opening or closing a folder) that refreshes the screen. Special Note to VL-Bus Users ---------------------------- The Power 9100 chip requires a 4MB address space to function correctly. The start location of this 4MB range is controlled by the wBase= line in the P9X00RES.DAT file, which is normally located in the \OS2\POWER_9K (for OS/2 support) and \OS2\MDOS\WINOS2 (for WinOS2 support) directories, and by the MemAddr= line in the P9X00RES.INI file in \OS2\MDOS\WINOS2 directory. The default memory base address is 80000000h. Not all VL-Bus motherboards support this default memory base address. If you get a black screen after installing these drivers and rebooting, follow the instructions on page 338 of the "Using the Operating System" manual for "Recovering from an Incorrect Display Type Selection" to return to VGA. Remove the Power 9100 drivers as outlined in the section above. Shut down OS/2, restart, then reinstall the Power 9100 drivers. However, before shutting down after the install, edit the P9X00RES.DAT files in the \OS2\POWER_9K and \OS2\MDOS\WINOS2 directories. Look for the line that reads: wBase = 80 Change this to one of the following options: wBase = 20 wBase = 40 wBase = 60 wBase = 90 wBase = A0 wBase = B0 wBase = C0 wBase = D0 Try each until you find one that brings up OS/2. Then, look for the following line in the P9X00RES.INI file in \OS2\MDOS\WINOS2: MemAddr=8000 If you selected wBase = 20 in P9X00RES.DAT, change the line to read: MemAddr=2000 If you selected wBase = 40 in P9X00RES.DAT, change the line to read: MemAddr=4000 If you selected wBase = 60 in P9X00RES.DAT, change the line to read: MemAddr=6000 If you selected wBase = 90 in P9X00RES.DAT, change the line to read: MemAddr=9000 If you selected wBase = A0 in P9X00RES.DAT, change the line to read: MemAddr=A000 If you selected wBase = B0 in P9X00RES.DAT, change the line to read: MemAddr=B000 If you selected wBase = C0 in P9X00RES.DAT, change the line to read: MemAddr=C000 If you selected wBase = D0 in P9X00RES.DAT, change the line to read: MemAddr=D000 Contacting DIAMOND ------------------ Diamond can be reached through a number of ways: Postal Service : Diamond Multimedia Systems, Inc. 1130 East Arques Avenue Sunnyvale, CA 94086 Voice (Main) : (408) 736-2000 Voice (TechSppt): (408) 736-2000 [M-F 6-7; Sat 8-4 Pacific] [plus 24hr automated help] FAX (Main) : (408) 730-5750 FAX (Support) : (408) 773-8000 BBS (to 2400) : (408) 730-1100 BBS (9600+) : (408) 524-9301 CompuServe : GO DMNDONLINE America Online : GO DIAMOND All product names listed are trademarks or copyrights of their respective owners. ======================================================================= Diamond Multimedia Systems, Inc.
