Release Information
Product: AudioDrive ES688 OS/2 Device Driver,
Version 2.01
Drivers: ES688 (with OPL3)
OS: OS/2 Warp 3.0
Part Number:
Release Date: October 24, 1995
Release Description
The AudioDrive ES688 OS/2 Driver Software Release incorporates
new changes done to the previous release, Version 2.0.
Version 2.01 Changes
The following changes have been incorporated:
1. The OS/2 driver fixes the problem that I/O base addresses 230
and 250 were not allowed.
2. The driver correctly resets the MIDI controllers after the
MIDI file is stopped.
3. The driver now can play fast tempo MIDI files.
4. The driver can play 8Khz wave files again.
New Features in Version 2.01
APM support
The OS/2 driver supports Advanced Power Management (APM). It is
recommended that users stop audio applications before putting
the system into suspend mode.
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.
2. Tempo in MIDI files is not 100% accurate due to timing delay.
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. There is a popping noise at the beginning of wave file play
when the PCM format has been changed.
Installation Notes
To install the new drivers successfully the following steps must
be taken:
1. Open an OS/2 Window and run the ESUNINST.EXE program on the
installation disk by typing "A:ESUNINST". This 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 ESS driver information in COMPLIST.INI.
2. Run the MINSTALL.EXE program on the installation disk by
typing "A:MINSTALL". Select AudioDrive ES688 by clicking
the mouse on that item. A checkmark means it is selected.
If WinOS2 is installed in the system, you can select ES688
WinOS2/Windows Audio support too. If not, make sure that
item is not selected. Click the Install button to start the
installation. Once the drivers are installed, shutdown and
restart OS/2 for the new ES688 drivers to take effect.
