Thank you for purchasing the Sounding Board (tm) adapter. The printed
manual enclosed with your adapter describes software and hardware
installation in detail.
Four executable programs have been included on the distribution disk
which are not described in the manual. HTEST, LTEST, RECORD, and SAY
are primarily for diagnostic purposes and their operation is described in
ASBTEST.DOC. SOUNDBD.EXE is the only file which you must copy for
the sound adapter to function. You may find SAY and RECORD to be useful
as well.
Remember to make a backup of your distribution diskette before you begin
installation. Also, fill out and return your registration form, so that
you will be notified of upgrades, etc.
ADDENDUM TO USER'S MANUAL:
One compatibility problem has been noted that occurs when the sound
drivers are used on certain '386 machines with '286 BIOS (specifically,
Everex 386 machines). When these computers are used with background
software (specifically, disk-caching programs) which use extended
memory, the DMA channel page register values are overwritten during
the extended memory move operations. Since the sound adapter uses
DMA concurrently with the caching mechanism, Sound DMA is redirected
to incorrect memory addresses, resulting in random noise at the
earpiece during playback, and in system crashes during record operations.
The DMA page register appears to be stepped on during the switch into
protected mode, which in '286 BIOS is accomplished by resetting the
processor.
There is no real fix to this problem, other than correcting the
Everex motherboard implementation, using a '386 BIOS to avoid
the RESET, or replacing the BIOS "Move Extended Memory" function
with a TSR that implements it correctly.
Until such a fix is available, a switch has been added to the SOUNDBD
driver program which partially overcomes the problem. Simply install
with the keyword "FIX_DMA_PAGE" switch on the command line, as in:
SOUNDBD VERBOSE FIX_DMA_PAGE
This will cause sound activity to be temporarily suspended during
extended memory moves. The result will be noticable "glitches" in
playback and recording, but no noise or system crashes. You should
NOT use this switch unless you have the problem, as unnecessary
glitches will be introduced.
USING MC-SOUND FROM A DOS VIRTUAL MACHINE
=========================================
The SAY.EXE and RECORD.EXE programs cannot be run from a DOS virtual
machine. The low level driver is disabled when Windows starts. Upon
exit from Windows, the driver is re-enabled and can be used from DOS.
Use ArtiSound to play and record voice files when in Windows.
ADDITIONAL INFORMATION FOR PROGRAMMERS
======================================
Artisoft's device identification number has changed. It is reflected in
the ASNBRD.H file.
ArtiSound now supports the extended wave format structure. This new
structure is defined as follows:
typedef struct extended_waveformat_tag {
WAVEFORMAT wf;
WORD wBitPerSample;
WORD cbExtraSize;
} EXTWAVEFORMAT;
Additional information on the new RIFF format is available from Compuserve
WINSDK forum or the Microsoft Multimedia BBS.
