2.2 Software Driver Installation

2.21 DOS Driver Installation

Note : If you use both of the DOS and MS Windows 3.1, you should skip the installation of the DOS driver of the Sound Card. Instead, you only need to install the Sound Card Window 3.1 driver which will work for both the DOS and Windows environment simultaneously.

DMA - direct Memory Access (DMA) is the electronic channel for moving data directly between main storage and peripheral equipment without requiring processing of the data by the CPU.
IRQ - Interrupt request (IRQ) is the request for processing on a particular priority level. It is generated by the I/O device (the add-on cards).
Port address - is the address used to specify port connectivity parameters and to assign link addresses for the certain I/O device.

2.22 Windows 3.1 Driver Installation



2.23 WINNT 3.51 Driver Installation

2.24 Windows 95 Driver Installation

Note : Install the Sound Card into the motherboard only after the Windows '95 has already installed into the new HDD of the new system, then restart the system and follow the procedure below..


Section 3 ~ 3D technology explained

Everyone knows what stereo sound is. But how the brain perceives it, is important in order to better understand 3D sound. For example, if a piano sound is played through just the left speaker then we will perceive the sound as coming from the left side. If the same sound (and same level, or volume, of sound) is also passed through the right speaker then it will create the effect of the piano sound coming from the center of the two speakers - in essence from a "phantom" speaker. By manipulating the levels of the audio signals to the left & right speakers, and then adding 'effects' to them, it is possible to create up to two extra "phantom" speakers - thus giving us 3D Sound. Further to this we must then understand two more '3D terminologies' - Sum and Difference...

Sum describes the information of each monophonic audio signal sent to the left & right speakers (in other words - the sound, and to which speaker). Difference is the information we have when we look at the left & right signals in terms of level, timing/delay and frequency. By subtracting the Difference of the right signal from the Difference of the left signal we come out with the all-important 'spatial' information which characterizes stereo program material - and it is this which can be manipulated to produce 3D sound.

The type of 3D sound used on this sound card was developed by a company called "Binaura" . This 3D technology has been used extensively and successfully by Creative Labs on their range of Sound Blaster sound cards. This type of 3D is not dependent on a specific chipset and software drivers, but more a mixture of sound card layout (the specific design of the routings of the audio signals, which are made when designing the PCB) and some passive components such as resistors and capacitors. This technology 'delays' and 'effects' the audio signals just enough in order to create the 'spatial' information so crucial to achieving good 3D Sound. The ensuing results of the "Binaura" design are an excellent quality of 3D sound which does not require software drivers, and is cheaper through design (not requiring expensive R&D & production investment in to core logic production).

4. Troubleshooting

Problem :No Sound During Normal Usage.
Solution A: Audio accessories improperly connected. Check that all audio accessories are plugged into the proper connectors.
Solution B : Volume control adjustment. Make sure that the volume control is not set too low.

Problem :No Visual Activity on Volume Meter.
Solution A:DMA channel conflict. Check that no audio accessories are attempting to use the same DMA channels and change DMA channels.
Solution B :The Sound Card driver is removed. Run setup to reinstall the driver.

Problem :No Sound or Receive Error Messages During Windows Starts.
Solution A:Another sound card driver is installed. If you install more than one sound driver in Windows, a conflict may arise. To solve this problem, you should remove all unnecessary drivers, and reinstall the Sound Card driver.
Solution B :The Sound Card driver is removed. Run setup to reinstall the driver.

Problem :No Sound in Windows 95.
Solution A :Configuration problem, you should check the configuration, use the manual configuration to set the Sound Card's resource.
Solution B :Either the motherboard does not support PnP function or the PnP option of the motherboard's BIOS is not enabled. To clarify these, please contact your motherboard dealer.
