AudioDrive ES1868 OS/2 Driver Version 1.04 Software Release Notes April 23, 1996 About This Release ESS Technology is providing updated OS/2 drivers for the AudioDrive ES1868 chip in this Software Release. These drivers are complete updates to prior ESS releases for OS/2 Warp 3.0. 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: AudioDrive ES1868 OS/2 Device Driver, Version 1.04 Drivers: ES1868 (with ESFM) OS: OS/2 Warp 3.0 Part Number: Release Date: April 23, 1996 Release Description The AudioDrive ES1868 OS/2 Driver Software Release incorporates new changes done to the previous release, Version 1.03. Version 1.04 Changes Better hardware volume control support A /H:# parameter can be added to the device driver line in CONFIG.SYS to specify the number of additional steps generated by one hardware volume control interrupt. The default number is zero. The maximum is 3. Wave files contention handling The driver can handle some wave files contention if it is not already handled by MMPM/2. Known Problems 1. 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. 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. 2. When Multimedia Application Install program brings up, a check mark beside AudioDrive ES1868 means that item is already selected. To toggle selection, click the mouse on the item. If WinOS2 is installed in the system, you can select WinOS2/Windows Audio support also. If not, make sure that item is not checked. Click the Install button to start the installation. Once the drivers are installed, shutdown OS/2 and reset the computer for the new ES1868 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. Since this version of 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. 5. If the MIDI plays are not smooth in WinOS2, 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. Since ES1868 is a plug and play board, in a system with plug and play support the optimal settings will be used instead of the settings specified in CONFIG.SYS. If you change the ES1868 settings in a system with no plug and play support, be sure to reset the computer for ES1868 to forget its previous settings.

After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
