Notes ----- - The drivers are designed to function only with an Obsidian 100SB. They will not work with with any other Voodoo Graphics based adapter, including the Obsidian 100DB. - When running RunMeFirst.bat you will receive a warning message if the version of Windows 95 installed is not OSR 2 or later. Windows 95 OSR 2 is a minimum system requirement for the Obsidian 100SB. You may proceed with the installation of the Obsidian 100SB, however operation may not be reliable. You may increase the chance of the Obsidian 100SB operating reliably by verifying that you have the latest system BIOS for your motherboard from the motherboard manuafacturer. Also, make sure that Windows is using the PCI bus defaults. To do this: 1. Double click on the System icon of Control Panel. 2. Select the Device Manager tab. 3. Double click on "System devices". 4. Double click on "PCI bus". The PCI bus Properties dialog will appear. 5. Select the Settings tab. 6. Click the "Set Defaults" button. 7. Click the OK button and restart if necessary. - On some computers, you may notice in the "Conflicting device list" on the Resources tab of the Device Manager property sheet for the Obsidian 100SB a message of the form: Memory Range: xx000000-xxFFFFFF used by: PCI standard PCI-to-PCI bridge and a complementary message on the property sheet for the PCI Standard PCI-to-PCI Bridge device: Memory Range: xx000000-xxFFFFFF used by: Quantum3D Obsidian 100SB These messages are benign and can be ignored. - Although multiple Obsidian 100SBs are supported in a single computer, XXX multiple Obsidian 50 Series and Obsidian 100DBs are not supported in the same system as Obsidian 100SBs. - All environment variables and WIN.INI settings that control behavior of the drivers are commented out by the driver installation. - If you have installed the Obsidian 100SB and now want to remove it and replace it with another Voodoo Graphics based adapter (including another model of the Obsidian family), you must remove the Obsidian 100SB drivers using Add/Remove Programs from Control Panel before installing the other adapter. Base Drivers Feature Set 1 Notes -------------------------------- The Glide 2.43.1 and Direct3D 2.14.1 drivers included in this release implement Base Drivers Feature Set 1, whose features for the Obsidian 100SB are: - Obsidian 100SBs and Obsidian 50/100DBs can not be mixed in the same machine. - Multiple Obsidian 100s (of the same type) can now be used in a single computer. - The Obsidian 100SB must be initialized by software before it is FCC Class B and CE Mark compliant. A service is run at Windows boot time that does this. - Gamma correction on the Obsidian 100SB now functions at 800x600. - The reliability of the Obsidian 100s have been vastly improved. - The Obsidian 100SB can operate at these video timings: Resolution Refresh Rate 512 x 384 72,75,85 640 x 400 70,75,85 640 x 480 60,75,85 800 x 600 60,75 - TV Out operates only when Voodoo Graphics is running and at these video timings: Resolution Refresh Rate Format Scan Option 640 x 480 60 NTSC Overscan and Underscan 640 x 480 50 PAL Overscan and Underscan 800 x 600 60 NTSC Underscan 800 x 600 50 PAL Overscan and Underscan - The default gamma for Direct3D is now the same as that for Glide (1.7). - Gamma correction and refresh rates can now be set via the Obsidian tab on the Display Property Sheet. - The SST_GAMMA, SST_RGAMMA, SST_GGAMMA, and SST_BGAMMA environment variables now control the gamma correction used by the Direct3D driver as well as overriding that set by Glide applications. - The Direct3D driver no longer uses the settings under the registry key: HKEY_LOCAL_MACHINE\Software\3Dfx Interactive\Voodoo Graphics . Frequently Asked Questions -------------------------- Q: Why is the Override Application Setting option in the Obsidian tab of the Display Properties dialog checked and not available (grayed out)? A: In order to maintain backward compatibility, environment variables set in C:\AUTOEXEC.BAT will take precedence over configuration options in the Obsidian tab of the Display Properties dialog. Therefore, if you have set environment variables in the C:\AUTOEXEC.BAT file, the corresponding configuration option in Obsidian tab of the Display Properties dialog will not be available. Removing these environment variables and restarting the computer will restore the previously unavailable configuration options. --------------------------------------------------------------------- Q: When TV output is enable the options for refresh rates for Glide and Direct3D are restricted to either 60 HZ for NTSC or 50 Hz for PAL Tv output. A: Enabling TV output restricts the refresh rate for the Obsidian 100SB to 60 Hz for NTSC and 50 Hz for PAL TV output in order to display the image correctly on the TV monitor. --------------------------------------------------------------------- Q: Why do some applications have corrupted display when the Wait for Vertical Retrace option in the Obsidian tab of the Display Properties dialog is not checked? A: Disabling Wait for Vertical Retrace may increase the performance of some applications because the hardware is not waiting for Vysnc to the display monitor however this may cause the tearing of images with the applications. For benchmarking purposes it is recommended that you disable Wait for Vertical Retrace for maximum performance. --------------------------------------------------------------------- Q: When attempting to run one of the Obsidian utilities by double clicking on the file in Windows Explore, a windows flashes and nothing appears to happen. A: You must run the software utilities from the MS-DOS prompt. From the Start menu select Programs then MS-DOS Prompt. --------------------------------------------------------------------- Q: When attempting to run an older Glide base application, an error message "missing DLL file 'GLIDE.DLL' not found" appears. A: The application is attempting to specifically access an older version of a Glide file GLIDE.DLL which has been replaced by the current GLIDE2X.DLL file. Contact the manufacturer for an updated version of the application. --------------------------------------------------------------------- Q: Why is the display corrupted to the TV monitor? A: Occasionally the output to the TV monitor may display incorrectly. Simply exit the application and restart it. --------------------------------------------------------------------- Q: Can the Obsidian 100SB be overclocked? A: Quantum3D doesn't endorse or support overclocking the Obsidian 100SB. The Obsidian 100SB is designed operate at 50MHz clock speed. --------------------------------------------------------------------- Q: Why is the Obsidian 100SB listed twice in the Device Manager tab of the System Properties dialog? A: The Obsidian 100SB is a single slot solution that contains two PCI devices connected to the PCI bus via a PCI bridge chip. The listings represent each device incorporated in the Obsidian 100SB. --------------------------------------------------------------------- Q: When attempting to run an application, an error message "Expected VXD version V1.2 got V1.1" appears. A: The drivers for the Obsidian 100SB have been overwritten or are the incorrect version or have been corrupted. Run RunMeFirst.bat, restart the system and reinstall the Obsidian 100SB drivers. --------------------------------------------------------------------- Q: On the Obsidian tab of the Display Properties dialog, the individual RGB ("Red", "Green" and "Blue") values configured are changed when the RGB option is selected. A: When RGB is selected, highest value configured for red, green or blue will be shown by the slider. However, changes in the setting are applied separately to the value of each component. --------------------------------------------------------------------- Q: A Direct3D application does not operate properly, locks up the system or has corrupted display. A: Some Direct3D applications were not written to operate correctly with SLI mode enabled. For these applications you may need to disable SLI mode. In addition to halfing the texture fill rate, disabling SLI mode reduces the effective frame buffer memory size to 2MB. This limitation only applies to Direct3D and does not effect Glide applications. Therefore, if you click on the Adapter Info button with SLI mode disabled, 4MB will still be listed for the frame buffer memory. In addition, when you disable SLI mode and select 800 x 600 resolution in the Resolution option, the Direct3D Test button will not be available. The Direct3D Test applet performs Z-buffering and requires 4MB of frame buffer memory (or SLI mode enabled) to operate at 800 x 600 resolution. Known Issues ------------ These will be fixed in a future release: - As mentioned above, the drivers are designed only function with an Obsidian 100SB. When used with any other Voodoo Graphics based adapter, they cause the computer to hang. The failure is intentional; however, it should be more graceful. - The Glide test applet currently only displays a static image unlike the Direct3D applet which has a spinning 3D model of the Quantum3D logo. - If you Alt-Tab to the desktop with the Direct3D test applet active and minimized and run another Direct3D application, an error will occur. - If you Alt-Tab to the desktop with a Glide or Direct3D application active and have enabled TV Out, the output to the TV is not shut off.
