ES1869 AudioDrive OS/2 Driver Version 2.10 Software Release Notes March 19, 1997 About This Release ESS Technology is providing new OS/2 drivers for the ES1869 AudioDrive chip in this Software Release. This document provides: - a description of the changes to the drivers - installation notes Please read this document completely before you upgrade your system, and follow the instructions carefully. Release Information Product: ES1869 AudioDrive OS/2 Device Driver, Version 2.10 Drivers: ES1869 (with ESFM and wavetable) OS: OS/2 Warp 4.0 and OS/2 Warp 3.0 Release Date: March 19, 1997 Release Description The ES1869 AudioDrive OS/2 Driver Software Release incorporates new features such as 3D Spatializer available in ES1869 AudioDrive chip. Known Problems 1. For OS/2 Warp 3.0, opening too many MIDI files makes the OS/2 system unstable. This problem is related to MMPM/2 and depends on system resource. On systems with 8 Mbs memory, the limit is 3; 16 Mbs, 6. 2. Tempo in MIDI files may not be 100% accurate due to timing delay and MMPM/2 architecture. 3. For OS/2 Warp 3.0, running MCI commands "seek wave to #" and then "play wave" to a 16-bit wave file sometimes generates very loud static noise. Likewise using "record wave from #" to record a 16-bit wave file may generate wrong file. It all depends on the seek position. 4. To be able to play and record wave files at the same time, the enforcement of only one active wave file by MMPM/2 is relaxed. Therefore, some problems or erratic behaviors may pop up if two wave files are played. 5. The OS/2 driver allows sharing of audio and MPU-401 interrupts, but it is not recommended. If both are shared, occasionally too much MIDI in data will lock up AudioDrive's interrupt processing when a wave file is played or recorded. To get out of this situation, stop the wave file, stop the MIDI in source, close all MIDI files, and restart the wave file to re-initialize AudioDrive's interrupt processing. 6. Due to the nature of MIDI music, turning MIDI in on while the MIDI in data are coming may not generate the right sounds. It is recommended to stop the MIDI in source first before enable MIDI in. Installation Notes To install the new drivers successfully the following steps must be taken: 1. Open an OS/2 Window and run the EINSTALL.EXE program on the installation disk by typing "A:\EINSTALL." The program first runs ESDETECT.EXE to auto-detect the chip, then calls ESUNINST.EXE to remove old drivers. That program will create a backup of CONFIG.SYS named CONFIG.ESS and remove the audio device lines from CONFIG.SYS. It also creates a backup of MMPM2.INI named MMPM2.ESS and removes the audio drivers information from MMPM2.INI. In addition, it removes any other ESS driver information in COMPLIST.INI. After then, the installation program calls Multimedia Application Install program, MINSTALL.EXE. After it finishes, another program, ESCONFIG.EXE, will be called to update CONFIG.SYS if necessary. 2. When Multimedia Application Install program brings up, a check mark beside ES1869 AudioDrive means that item is already selected. To toggle selection, click the mouse on the item. Click the Install button to start the installation. Once the drivers are installed, shutdown OS/2 and reset the computer for the new ES1869 drivers to take effect. 3. If the installation cannot be completed, read the logs EINSTALL.LOG in \MMOS2\INSTALL subdirectory and MINSTALL.LOG in \MMOS2\INSTALL subdirectory or root directory to find out the problem. 4. If during the installation an error saying the audio device is already in use by another application comes up, make sure all applications that utilize audio have been closed. If this is caused by system sounds not closing the audio device, you have three options to remedy this situation: A. Remove the audio driver by running ESUNINST.EXE. B. Go to Sounds object in System Setup folder and uncheck Enable system sounds option. After the driver is installed properly, check the option to enable system sounds. C. Run DINSTSND.CMD in d:\MMOS2\INSTALL subdirectory. After the driver is installed properly, run INSTSND.CMD d: to enable system sounds. Perform one of these operations and reboot to disable system sounds. Install the drivers again. 5. If WIN-OS/2 is installed in the system, start WIN-OS/2 and run "A:\SETUP" to install WIN-OS/2 drivers. Change the WIN-OS/2 settings to the following if necessary: AUDIO_ADAPTER_SHARING = Required INT_DURING_IO = On 6. Since OS/2 Warp 3.0 MINSTALL.EXE changes the icons of MIDI player and Digital Video player to that of Digital Audio player in the Multimedia folder, you may want to change them back to the originals. To change the icon of MIDI player, right click MIDI player to bring up the menu. Select Settings, select General, and click the Find... button. In the Start Folder window, enter \MMOS2\INSTALL. Click the Find button and a window of all found icons appears. Select MIDIPLAY.ICO and click OK. Close the MIDI player Settings notebook. For Digital Video player, repeat the above steps but select VIDPLAY.ICO instead. 8. If the MIDI plays are not smooth in WIN-OS/2, you need to change the timer resolution. Edit SYSTEM.INI in your Windows directory. Under [timer.drv] are TIMERMax386Res and TIMERMax286Res. You need to change the values to less than 8 from the default of 10.
