What drivers exactly are you looking for?

Audio driver for example (for Analog Devices 1881A): https://web.archive.org/web/20060222102003/ht … nd/ad18819x.zip

For chipset drivers for the Intel 845 chipset, you might want to head over to Phils Computer Lab: https://www.philscomputerlab.com/intel-chipset-drivers.html

Thank you. I was looking for Windows 98 SE drivers

I've installed the chipset drivers and audio drivers from the links you posted.

All seemed to install to be OK but when I boot into windows I get a message to say the audio hardware i not responding correctly. If you click it three times then windows continues to load but I don't have any sound.

In the device manager the sound card seems to be installed OK. Possibly the driver link was not the right one?

Saw a post on another forum of a user with same board but different OS - WIn 2K SP4. They tried the AD1881 drivers with same effect - SoundMax device manager entries but no sound. Someone suggested to try other sound codecs so having had no luck with ALC201, they tried Crystal 4299, and success! 😀

OK thanks
I'll give that a go, looks like they are here

http://www.soundcard-drivers.com/companies/263.htm?o=8

You could also try the QDI drivers link already posted by @gex85 above, as both ALC201 and Crystal 4299 drivers are listed there.

So I have the same problem - I can't download from soundcard-drivers.com (I flat out just don't know how) but I got the files from here:

https://www.driverguide.com/driver/detail.php … driverid=228954

Installed them. There is sound, but it sounds like a modem. That someone stepped on. And put underwater. The computer is in pain! Wretched sounds.

I have WinXP installed on this machine as well, and the card there works just fine. It is listed as:

Intel 82801BA/BAM AC'97 Audio Controller.

This site has a few more options, but so far, nothing has worked.

https://web.archive.org/web/20051128015848/ht … _downloadcd.htm

So I downloaded a file called INF2K that claims compatibility with 98 and when I go to the General tab (in 98's system properties) I get NTKERN.VXD, MMDEVLDR.VXD device loaders for this device could not load the device driver (code2)

It does see the device as the 82801BA/BAM controller though.

I replied in your other thread, but I've no idea if that download will help or not.

None of those drivers worked. After installing the SoundMax and the Cirrus ones Windows 98 kept autofinding them and installing those over anything else upon OS start / when I asked it to find more hardware. After a few ghost sessions (I have two of these systems, I had an image stored) to restore the baseline, and spending far too many hours on this, I threw a CT4810 at it, disabled the onboard sound (which worked fine in XP) and called it a day.

Strange, as this board came out in 2001 - I don't see why the OEM didn't provide Windows 98SE drivers, as the OS was only 2 years old at the time of the motherboard release. Maybe they did, but as of writing this in 2020, I can't find them.

OK so this is weird - I just picked up 4 more of these systems, same config as far as I can tell (it was almost a year ago to this date) and I had long repurposed the drive with the XP/Win98 partition, however, I took a copy off a random NEC Celeron machine that had XP/98 (guess what - XP had to be reinstalled 🤣) but whatever drivers were on Win 98 for the sound actually took! I mean, there's no FM synthesis, NSSI tells me it's the same card as in the computers I picked up last year, but the drivers loaded on the image outgoing the NEC are Vinyl AC'97 Codec Combo Driver (WDM)

C:\WINDOWS\SYSTEM32\DRIVERS\vinyl97.sys
C:\WINDOWS\SYSTEM32\VMM32.VXD (ntkern.vxd)
C:\WINDOWS\SYSTEM32\MMDEVLDR.VXD

VIA technologies
File version 6.14.01.4150 built by WinDDK

I'm not sure what to say here - complete fluke?

No direct DOS compatibility though.

*edit - yep all four work.

man, put jumpers on FPAA and you will have sound

According to the website the sound chip is as follows:

Onboard Audio(available on PlatiniX 2-A/-AL, PlatiniX 2I-A/-AL)
AC’97 2.1 Specification Compliant
16bit stereo codec
Multiple stereo input mixer
Mono and stereo volume control
Provides onboard Line-in Jack, Microphone-in Jack, Speaker-out Jack with onboard amplifier and MIDI/Joystick Connector
Upgradable to 6 channels audio with CNR card

Notice the 6-channel upgrade option. Also notice what it says on this site:
http://ixbtlabs.com/articles2/roundupmobo/qdi … e-6a-i845e.html

audio controller based on the ALC650 AC'97 codec supporting 5.1 audio systems and having an SPDIF connector.

Did you try the ALC650 driver?

Also did anyone really look on the motherboard to identify the audio chip? I can't tell by the picture, need closeup.

Thanks for the pointer - haven't had a chance yet.

Here's a pic of the DSP:

What jumper are you referring to?

**EDIT** - Scrub this as I think we've been down this rabbit hole already 🙁

OK, based on your IC pic and this page link

maybe give these a blast 😀
