3. RELEASE NOTES
A. General information
This release provides Windows NT 4.0 and NT 3.51 drivers for
1815/1816/1816A products. These drivers are in process of
certification by Microsoft for the "Designed for Windows NT".
In addition, provisions are made to customize the Win NT Mixer initial
settings to desired initial conditions. This applies to visible names,
default volume levels, mute state, and presence of any selected mixer
lines.
We recommend that you decide on the initial Mixer settings, and define
the adisound.ini file BEFORE you install the drivers. This is an
important first step.
B. CHANGES IN THIS RELEASE
3.1 Hardware volume control offset corrected (for boards with hardware volume control).
3.2 20dB Gain Control in microphone added on the mixer.
3.3 XC0,1 Control added on the mixer.
3.4 HELP screens provided for settings page in Multimedia Panel (AD18xx.HLP).
3.5 Fixed problem with playing MIDI under 3.51 without setting MIDI MAPPER.
3.6 Remove code for Mute DAC when there is no DMA activity.
3.7 Fixed problem with recognizing Vendor ID in INI file.
3.8 Fixed problem with lines that could not be disabled from INI.
3.9 Change default values for hardware volume control in INI file (for boards with
hardware volume control).
3.10 Added code to support extra logical device specified in INI file (1 extra device-
1 tuple, no DMAs, no IRQs).
3.11 Disable of options on settings page that are not configurable at installation time
(20dB Boost, I2S0 format, I2S1 format and clock multiplier).
3.12 Midimap.cfg initializes the MIDIMAPPER for Windows NT 3.51.
3.13 Fixed problem where physical connection at XCTL1 was controlled by both XCTL0
and XCTL1.
Limitations of this release
Win NT 4.0 is not a Plug and Play operating system in the extent featured in Windows 95.
This single fact is the cause for much confusion with OEM's who are most familiar with Win 95.
Drivers must be removed by the USER, and new drivers must be installed by the USER.
The operating system will not perform this automatically.
The driver is provided with an ADI PnP algorithm, and as such, the NT PnP file provided
with the NT 4.0 release CD ROM should NOT be used. This file is called PNPISA.SYS.

4. INSTALLATION INSTRUCTIONS
System preparation:
4.0: Removing Previous driver revisions
The first essential step is to remove previous Analog Devices driver revisions
using Windows NT supplied tools.
*Make a backup directory on your hard disk, and copy all the files
from the driver diskette and unzip the files
*Verify that you have an AD1815 or AD1816 or 1816A SoundPort Controller
soundcard in your system
4.0.1 Open the Control Panel/Multimedia folder.
Click "Devices" to view the list of installed devices
Open "Audio Devices" , click once on the Analog Devices driver
Click "Remove"
A warning dialog box will ask you to confirm, Click Yes.
A System Setting Change dialog box will confirm the driver removed, and ask for a restart.
Click "restart now"
4.1: Configuring the Mixer settings BEFORE installation.
The file ADISOUND.INI allows an OEM to configure the initial settings
for the WIn NT 4.0 mixer. You can set the 'presence' of any particular
input, the initial value, name the input or output, and set the mute
status of the signal.
4.2.1: The first line allows an OEM to specify a VendorID , to associate with the
design and uniquely identify it.
For the case of using the 1816/1816A internal EEProm, these values are
provided in the file. You do not need to change anything.
For the case where an OEM has used the external EEProm and has specified
their own VendorID, the value in the adisound.ini file MUST correspond to
the value in the EEPRom.. This is essential, as the driver compares the two
values to identify a correct part. The driver will load if the values match,
The driver will report an error message if the values do not match.
The top of the file looks like this:
[OEM_PARMS]
VendorID="ADS7180/FFFFFFFF,OEM7181" (this is a sample format)
These values identify the 1816 and 1816A Vendor IDs.
4.2.2 Adding an OEM specified value:
The 3 alphanumeric characters are the OEM's registered manufacturers ID code.
For example, ADS is the code assigned by the EISA committee for Analog Devices Inc.
The values 7181, 7182 identify a 1816 and 1816A code, programmed internally.
The values 7150 identify the 1815 part.
The card ID code must be unique in the manufacturers product line and can be
4 hexadecimal characters maximum.
For example, assume a registered company ABC, with product 123F. The first line would be:
[OEM_PARMS]
VendorID="ADS7180/FFFFFFFF,OEM7182,ABC123F"
Note: Do not insert any spaces. The "/FFFFFFFF" is not required.
4.2.3 Burning the EEPRom with a matching VendorID code.
Please contact ADI customer support to convert the OEM string ABC123F, into a
binary value to burn into your EEProm.
ADI also supplies tools for users to build their own EEPRom and
to load it into the EEPRom.
Use on the External EEProm assumes the user has full and up-to-date knowledge
of the PnP ISA specification originated on MAy 5, 1994 Version 1.0A
Refer to page 30, section 6.2.2.2 for critical information regarding
programming resources on your own. This is a very complex topic.
The format of the first word of the vendor ID (e.g. ADS) is "ASCII compressed EISA ID".
4.3 Setting Default and initial Mixer settings:
The ADISOUND.INI file provides control over each input to the Win NT mixer.
This file is stored in the C:/WInNT/system32 directory after installation.
The file is organized for each input, as follows;
[LD_SpeakersOut] " LD refers to Line Destination, and is the main line output"
LineNameShort= " This is used for the Win NT 3.51 Mixer"
LineNameLong= " Is used to define a visible label that appears on teh WIn NT mixer"
LinePresence=1 " This is the enable flag. IF set true, (logic 1) the unit is displayed.
" IF reset (Logic 0) the unit is not visible."
" The LD_SpeakersOut is programmed not to respond to presence = 0"
Volume=32767 " This is the initial level of the SpeakersOut on boot up. This control responds to"
" values in the range 0 to 65535 (minimum to maximum) "
Mute=0 " This is the state of the mute control, 1 means On, 0 means Off"
Hardware Volume " This is reserved for future use"
The remaining signals follow the same format. Refer to the ADISOUND.INI file for
the complete format and listing. Complete the desired initial settings for the remaining controls.
They are:
[PB_LineIn] " PB refers to Playback controls "
[PB_WaveOut]
[PB_MidiOut]
[PB_CDRomIn]
[PB_MicrophoneIn]
[PB_MonoIn]
[PB_VideoIn]
[PB_SynthesizerIn]
[PB_I2S0]
[PB_I2S1]
[PB_PhoneIn]
[PB_PhoneOut]
[PB_3DSurround] "Refers to ADI Phat stereo'
[RC_LineIn]
[RC_MicrophoneIn]
[RC_CDRomIn] "RC refers to Record controls"
[RC_SynthesizerIn] "Refers to the OPL3 on-chip FM synthesizer"
[RC_VideoIn] " Refers to the input labeled Aux3 on the datasheet"
[RC_MonoIn]
[RC_LineOut]
[RC_ModemIn]
[RC_PhoneIn]
When you have completed your selections, save the ADISOUND.INI to your installation disk.
You are now prepared to install the NT drivers.
4.4 Installing NT drivers
4.4.1 Open the Control Panel/Multimedia folder.
Click "Devices" to view the list of installed devices
Click "Audio Devices" and the "Add" button
Select the "Unlisted or Updated Driver" entry, click the OK.
the "Install Driver pop-up requests to insert the driver disk, click OK.
the "Add Unlisted or updated driver pop-up appears, click OK.
the "Configure Analog Devices Soundcomm" pop-up presents the default settings,
Click OK and the driver is installed. Win NT will restart the target system.
You have now successfully completed the installation.
