The above is very roughly translated from German but it's obvious what must be done, download the 2 files and add the line illustrated to the autoexec.bat

Does anyone agree it is cool news?

I didn't realize AC'97 was a problem in DOS. Any machine I've used with AC'97 sound onboard has worked fine in DOS with no need for a specific driver file as far as I can remember. But then, I've been using AdvMame in my DOS cabs which has a built in AC97 driver. Hmmm...

I didn't realise that AdvMAME had a built in sound driver, I will have to use that ASAP.

...still, we'll pretend that I was the first to discover something potentially usefull... like Vantage and Raine might not have AC'97 drivers built in.

Thank you,

That's excellent news. I've been after an AC97 DOS driver for a long time.

It appears you also have to change some BIOS settings. If you put the text through Babelfish you get the following:

VIA AC97-Chip With the AC97-Chip VIA an unparalleled Schlamperei afforded. On some driver CDs the important driver file was directly forgotten viafmtsr.com! For the sake of the completeness it gives here also viaudio.com to the Download. With these drivers the chip in the MSDOS mode makes however no problems. In auto+EXEC-ASKED the following instructions must be added and adapted if necessary:

LOADHIGH C:\DOS\VIA\VIAUDIO.COM
LOADHIGH C:\DOS\VIA\VIAFMTSR.COM
SET BLASTER=A220 I5 D1 P330

In addition the option must be activated "Onboard Legacy audio DEVICE" in the BIOS Setup of the computer. The values for storage address, IRQ and DMA (direct memory access), registered in the BIOS, must agree naturally with those in auto+EXEC-ASKED.

Here's a link to the thread where I told you where to get this driver (only from the manufacturer, rather than from some German site):

And here's the thread where I mentioned it under my old alias back in 2004:
