1.Remove any NT SNDSYS/SNDSYS32 Devices Boot your computer into windows NT 4.0, delete sndsys.sys and sndsys32.dll and remove any devices from the machine or Windows using these files. (I doubt there are any but we don't want conflicts)
TOM - Deletion is not necessary because OS asks if so-far-file is to be overwritten. Also if you haven't added multimedia NT components you can add some by using your NT CD.
2.Add the ADF "@DFE5.adf"-file to your machine's Reference Diskette
NOTE: If system supports "Copy an Options Diskette", copy ADF to system / convenience partition BEFORE adding card. Quite frustrating dropping in a new adapter, then finding out that the ADF can't be read from the floppy. [ed.]
3.Shut Down System, Install Ultimedia Shut down your system and add your DFE5 IBM Ultimedia Card. NOTE: IBM would suggest that you also unplug your system [ed].
4.System Programs Adapter Settings - Boot, go into system programs, and set adapter to the following: CRITICAL!
Slot x - "IBM Ultimedia Audio Adapter"
"Adapter Record DMA Level Select - "DMA Level 3".
"Adapter Enable / Disable Channel Burst" - "Disable Channel Burst " (? See ADF section)
"Adapter I/O Address Range" - your choice! "I/O Ports 500-50F"
"Adapter Interrupt Level" - "IRQ 9 " (TOM other IRQs not supported yet!!)
"Adapter Playback DMA Level Select" - "DMA Level 1"
"Adapter Fairness Select" - "Disabled"
"Adapter Enable / Disable" - "Ultimedia Adapter Enabled "
For upcoming use NOTE DOWN your choice of playback-DMA and I/O-address, precisely: its starting address (e.g. "500")!
TOM - No problem if wrong because OS checks, changes, and informs you in case of necessity.
NOTE: Though system programs will identify any conflict in adapter settings, there is hell to pay if you set up the resources differently under NT4! [ed].
5. ALWAYS CHECK For Resource Conflicts! Look for an asterix in system programs next to the resource to detect any conflicts. Manually adjust all conflicting device settings properly!
NOTE: As of this time, the Ultimedia does not have much flexibility in resources, so if there is a conflict, try adjusting the settings for the other adapter / device that has the conflict [ed].
6. Reboot - if you can and login to your windows NT machine you are half way there.
7. Add NT Ultimedia Drivers Go to Start > Settings > Control Panel > Multimedia > Devices > Add > Unlisted ... Driver > Browse > [path to files] > Ultimedia... >
8. Windows Control Panel > Multimedia Devices -Click on the radio buttons to match the resources you chose (and noted) in Reference Disk Setup: Choose playback-DMA, I/O-start-address and interrupt 9
I/O Address - same as in System Programs
Interrupt - Interrupt 9Record DMA Level is not in the Properties. You didn't miss it.
9. "Advanced Settings" - max buffer to 64k. Checking the "Use Single DMA" is up to you, the driver doesn't support duplex transfers so it really doesn't have much effect - if at all.
WARNING! Do not mix up the DMA Levels between the System Programs and NT Control Panel! I wanted to reverse the DMA levels inside system programs, then do the same under NT4. NT black screened. Had to power cycle to get into system programs and reset. [ed.]
10. Click OK twice.
11. Under Windows NT drivers are dynamically loaded so you don't have to restart if you don't want to - although the text popping up alleges so. TOM's remark: true!
12. If it doesn't work and you are SURE you didn't do anything wrong, email me with your system specs. E-mail with questions or bugs: HERE

ADF Sections for @DFE5.ADF IBM Ultimedia Audio Adapter ver 3.3
Adapter Record DMA Level Select DMA level used for audio
recording MUST be different from other adapters AND
MUST be different from Adapter Playback
Adapter Enable / Disable
Channel Burst This
enables or disables channel burst mode.
Recommended setting is enabled. Allows the adapter to
use a burst-mode where it can have complete control of
the DMA channel for up to 12mSec
Adapter I/O Address Range selects I/O address used by the
adapter. No default as long as the range does not
conflict with another adapter.
Adapter Interrupt Level Enables the IRQ that will be
used by the adapter. IRQ9 is default.
Adapter Playback DMA Level Select selects DMA level used for
audio playback MUST be different from other adapters AND
MUST be different from Adapter Record DMA
Adapter Fairness Select Enables or disables
MicroChannel Fairness feature. Recommended setting is
disabled. If 'Fairness' is enabled, the Ultimedia
Adapter will not compete for the channel during the
next arbitration phase if it is currently in control
of the channel.
Adapter Enable / Disable This option enables or disables the
Struggles for an ADF
Ryan Alswede managed to beat this out of the card:
Ultimedia Sound Card
request buffer 50
connection address 4
(The card is in slot 4 in the machine which is the last MCA slot)

The Ultimedia is a codec only based adapter that offers the advantage of quick, cost effective software upgrades to enhance function and performance versus hardware modifications or additional cards. The Ultimedia design eliminates extraneous audio hardware support requirements beyond the codec chip. The codec chip provides for data conversion between the analog audio signals and standard digital audio formats.
