Audio Support Under Real Mode DOS
[Systems with Win95/DOS Setup] To enable support for DOS Games or
multimedia applications under a REAL MODE DOS environment, please
follow the Step 12 of INSTALL PROCESS. If you decide not to do DOS
setup now, it’s OK to skip it. Type C:\SND4DOS at real mode DOS prompt
at any time will bring up the DOS Installer.
[Systems with Dual Boot Win95/Win31 Setup] Please run OPTi’s Win31/
DOS Install package at Real Mode DOS prompt. When prompted during
the installation for the path to your Windows directory, specify the path if
you have Windows 3.1 installed on your system (under a separate direc-
tory from Windows 95). Select None if you do not have Windows 3.1
installed.
Audio Support Under Windows 95 DOS Box
DOS Game support has been added for this release and is fully functional.
During the setup for your DOS games, you must ensure that the current
resources assigned to the sound card matches with the current settings
requested by your DOS game. To find out what resources are currently
assigned to the sound card, proceed to open the properties box associated
with the “OPTi .. Sound System” (Device Manager) and select the Re-
source tab. From the Resources box, you should see the current I/O Ad-
dress range for Input/Output Range Number 1. We recommend the 220
Hex address range as opposed to the 240 Hex be selected as most games
support 220 Hex by default. We also recommend the Interrupt and Direct
Memory Access settings of 7 and 1 respectively. Reconfigure these re-
sources as appropriate and select OK for Device Manager to dynamically
change and update your current resources and configure the hardware. At
this point, you may setup your DOS game with the settings which you
have just configured.
Also, if you have a Wave Table Device on board or attached to your sound
card, you should also follow the recommended steps above but this time
check on the “OPTi .. MPU-401” device settings instead. You will need
it’s current settings if you wish to enable General MIDI support in your
DOS games.
