- Description
- -----------
- These drivers provide OS/2 multimedia audio support for the Advanced Gravis
- UltraSound line of audio cards. The drivers support simultaneous playback of
- WAVE and MIDI audio streams through the UltraSound card.
-
- Installation instructions
- -------------------------
- To install the drivers, unzip this package onto a floppy disk and run the
- OS/2 MINSTALL utility. Select UltraSound from the list of installable
- drivers, and respond to the installation program's inquiries about your
- UltraSound. Once the install script has completed, reboot your machine.
-
- NOTE: If your UltraSound software is installed in a directory other than
- C:\ULTRASND, you will have to adjust your config.sys file. Change
- the line:
-
- RUN=C:\MMOS2\ULTRALDR.EXE C:\ULTRASND\ULTRASND.INI
-
- to point to the actual UltraSound directory. Eg, if your UltraSound
- software was installed in D:\SOUND\ULTRA, then change the line to:
-
- RUN=C:\MMOS2\ULTRALDR.EXE D:\SOUND\ULTRA\ULTRASND.INI
-
- Known limitations
- -----------------
- These drivers are ALPHA drivers and, as such, are unsupported by Advanced
- Gravis. The drivers have the following known limitations, which will be
- addressed in future releases:
-
- - 44KHz 16-bit stereo WAVE files may play with crackling and popping sounds
- on some machines.
-
- - MIDI patch loading is optimized for cards with at least 512K of GUS
- memory on board. UltraSounds with 256K of memory may experience
- performance and sound problems while playing MIDI files.
-
- - The driver provides no explicit support for DOS sessions. This means
- that if a DOS session tries to access the UltraSound card, it can, but
- it might corrupt the state of the UltraSound drivers. To restore the
- state of the drivers, after using DOS audio, try doing the following:
-
- 1) Run ULTRINIT in the DOS box and set up the mixer appropriately,
- 2) Run ULTRALDR (supplied with this package) in an OS/2 session with
- the parameter "<Flush>" (quotes required). This will instruct the
- driver to ignore any currently loaded MIDI patches and to reload
- them when necessary.
-
- Problem reporting
- -----------------
- As this is the first Alpha release of the drivers being distributed, it is
- likely that new difficulties ("bugs") with the drivers will be discovered.
- If you discover a problem that has not been addressed in this README, then
- please fill out the TECHINFO.DOC form and e-mail it via the InterNet to:
-
- os2.driver@gravis.com
-
- Goodbye
- -------
- Thanks for taking the time to try out these drivers. Look forward to future
- updated releases of these drivers to be released within a short time after
- this release.
-
- Have a Merry Christmas and/or Happy Holidays, and
- Enjoy using your UltraSound under OS/2...
