Windows' DOS session.
---------------------------------------------------------------------
0.) What's NEW in this release
- When Intel's CM (Configure Manager) isn't present, the
program will check whether the sound card has been
configured by the PnP BIOS and if the configuration is
good. It may try to get system resource information from
the PnP BIOS and assign conflict-free resources to the
sound card if it is necessary. In most of the cases the
program detects no error during the configuration, so user
don't need to do the resource selection. However, if your
system doesn't have PnP BIOS, or on your system there is a
legacy device, (that is, the PnP BIOS doesn't know what kind
of resource it may use) whose resource conflicts with the
resource assigned to the sound card, it is necessary that
the user involves in choosing the resource for the sound card.
- The users can always select the resource (Hardware Settings)
they prefer by using /S option when there is no Intel's DOS
CM loaded. But it is suggested that the user use this option
only when the sound card cannot work correctly if running
SNDINIT without /S. That may cause by inacurate information
from the PnP BIOS, that is, the system has some legacy cards
whose resources conflict with the sound card's.
- When Intel's CM (Config Manager) isn't present,
the WSS uses dual-DMA as default (that is, when the codec
supports dual-DMA and the system has two DMA channels
available, the WSS will always use dual-DMA). But by using
/S option and choosing single DMA channel can overrule
this default.
- Windows 3.1x driver gets sound card resource assignment by
reading the sound card PnP resources in stead of reading
the system.ini file. Should the users make any resource
changes, they need to go back to DOS and run SNDINIT (/S).
- SNDINIT program will try the best to make sure all hardware
settings are good for existing DOS games or applications
even if they are not assigned to proper ones by the PNP BIOS
or CM at first. The SNDINIT will give the warning messages
on DOS games/applications compatibility if no way to get the
right hardware resource.
- During the sound card installation (run INSTALL from a floppy
drive), or configuration (run SNDINIT from any DOS prompt),
if any warning occurs, the program will display the message
on the screen and save the message in the SOUND16.LOG file.
- Add EXT_OPL3_CONTROL=NO at the system.ini. If the FM OPL3 is
conflicted by other device, the user can set this option to YES.

2.) DOS/WINDOWS 3.1 DRIVER INSTALLATION PROCESS
!!! Note: For Windows users, please exit from Windows and run
the installation from DOS. !!!
The installation program, INSTALL.EXE, will copy the necessary
files from PHILIPS Installation disk into your hard
disk. Follow the following procedure to install the software:
(Assuming you are using floppy drive A, and you wish to install
to hard disk drive C)
1. Place disk 1 in Drive A.
2. Type a: and press ENTER to change to Drive A.
3. Type "install" and press ENTER to begin the installation.
INSTALL.EXE will do the followings for you:
a.) Create the directory \PCA721AF in your hard disk drive.
b.) Prompt you for sound card options so that after you
have finished the installation and have rebooted your
machine, you will be ready to use the sound card.
c.) Copy the files in your floppy disk to the PCA721AF directory
and Windows directory respectively.
d.) Update your CONFIG.SYS, AUTOEXEC.BAT and SYSTEM.INI files
In CONFIG.SYS
DEVICE=C:\PCA721AF\CDSETUP.SYS /T:X
In AUTOEXEC.BAT:
PATH=C:\PCA721AF (appended)
SET SOUND16=C:\PCA721AF
C:\PCA721AF\SNDINIT /B
SET BLASTER=A220 I5 D1 T4
^
|
+------- IO: 0x220, IRQ: 5, DMA: 1
In SYSTEM.INI:
- [drivers]
WAVE=SND924.DRV
AUX=SND924.DRV
MIDI=SND924.DRV
MIXER=SND924.DRV
- [386Enh]
DEVICE=VSND924D.386
- [snd16.drv]
SingleModeDMA=YES
CodecType=CS4231
* SND924.DRV is the Base driver comprising WAVE,
MIDI, MIXER and AUXILIARY audio services.
3.) Run DOS games in Windows 3.1
a.) Sometimes, the Setup of the PIF file of a DOS game is crucial.
To make a game work effectively under Windows, you probably
have to try a few alternative options through PIF editor.
b.) Not all the DOS games can run in Windows' DOS BOX. Some of
them just don't run because of system restrictions.
Download Driver Pack
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.
