I went into Device Manager, and manually configured the IRQ to 7, Address to 220, and DMAs to 1 and 5, respectively (generally considered the 'default' settings, IIRC).

I'm not clear on why you felt the need to do that..? IRQ 7 actually tends to be problematic as it is often already taken by the parallel port. I know in some contexts it's described as the "default" but I don't think I ever encountered anything that forced you to use IRQ 7 and nothing else.

On that note, if you're not using the serial ports and parallel ports on your motherboard, you should probably disable them in your BIOS.

I'm a bit fuzzy on which versions of CTCM work with Windows and so on, but if no one else chimes in there should be ample documentation supplied with the drivers themselves.

(Also, it's probably a bad idea to refer to the "MS-DOS Prompt" in Windows 95 as DOSBox. That just confuses people.)

Thanks for the reply.

As for why I made the manual changes:
A) I have indeed removed my printer port and disabled it in BIOS, so there is no conflict issues there.
B) I started reading some documentation indicating what the default values were, particularly in the early days of SB cards. Since I wanted compatibility with any games which might be hard coded to IRQ 7, I changed it. Also, when I first installed the card, Windows/the SB installer set the IRQ to 10- a value that doesn't even exist as an option in the Doom sound setup. So it seemed to me that it was safer to set them down at the 5 or 7 neighborhood, for game compatibility.

I will re-read the README texts in the driver files, but they are mostly geared towards DOS/3.11 installation, and seem to just say "hey, 95 supports PnP, so do what you do and have fun"- not much else, but I'll re-read anyway.

And I shall stick with DOS prompt from now, thank you. I only called it DOSbox because, well.. Windows 95 actually refers to it as "DOS Box" when shooting back errors regarding shell integration. Pretty sure that's where DOS Box got the name from, but you're right, it avoids confusion.

Where did you get your drivers from? I think you might need sbw9xup.exe .

I reckon you shouldn't worry about that until you actually encounter such games, as they'll probably have all sorts of other compatibility problems.

I will load up the disc after I return from finals this afternoon, but I know for a fact I used this SB16 ISO from the Vogons library (http://www.vogonsdrivers.com/getfile.php?file … menustate=42,35) It has drivers for 6.2, 3.11, and 95, but I don't recall an exe by the name of sbw9xup, that's true.

LIke I said, I ran into a proximally relevant issue with Doom- in the sound setup, it gave me a list of IRQ options to choose from, but the list only went up to 7. If I'd stayed with the IRQ of 10 that windows defaulted to, I'm not sure it would have worked. Then again, it only sort of works as it is...

UPDATE: After running into a HIMEM issues related to my latest attempt to install a COAST module on the mobo, I was forced to restart Windows in safe mode and then restart the system. On a wild hunch, I attempted to run DIAGNOSE again...

...total success! All IRQ, DMA, and Address settings passed (using auto, which chose all the settings I'd manually picked in Windows anyway) and it successfully wrote to the SB16 drivers and SYSTEM.INI file. On a restart, I suddenly got the classic 95 boot sound, and DOOM, DOOM II, and Wolf3D all operate with normal music as well as FX. I don't know why what happened happened, but there you go..

Next question, if anyone could be so kind- what is the purpose of these jumpers?

The first has two rows- an on/of (JP11) for RSPK_EN (Don't know what this function is) and a 4 position gang (JP14) for AUDIO_PWB (not sure what this is either).

Does this have to do with the audio pre/post amplification? And if so, how, and on what outputs?

The second pick is a mystery 3 pin jumper simply listed as JP15. Any ideas?

I don't believe so. Creative cards either have four jacks where two are the line and speaker (amplified) outputs, they have a standard jumper block for enabling or bypassing the amp (as in CT41xx Vibras), or (like my CT2770) they omit the output amp entirely and just ship a line output.

Some info on AUDIO_PWB (the diagnostic pins).
