What type of Dos machine?

More information would be ever so helpful. Know cpu type, ram type/size and other "stuff".

We are not mind readers.

Most CD drivers look into "standard" IDE addresses (0x1F0, 0x170) and they won't find controllers placed at other addresses unless told so. Maybe you'll have to put some parameters on the CD-ROM config.sys line.

CDrom is connected to soundcard with CS4237b chip.

Why? Not enough IDE connectors on the motherboard?

I'm sorry. I'm using 486DX2, 8 MB 30 pin simm, and some unnamed motherboard with ami bios and UMC82C491F chipset.

This unnanmed motherboard does not have any ide connectors

Will try this. Also the driver allows me to set following adresses : 320, 340, 350, 360. Maybe I'm stupid but I don't see these 'standrad' adresses here.

You mentioned you've been using oakcdrom.sys etc, I suggest to try the .sys file that comes with the sound card drivers/software.
Also there are cases where the ide connector must be "enabled" either from the card's configuration utility or some initialization utility.

In the only drivers I've found there is no .sys file, sadly. In the configuration utility I set ide to enable. Although the IDE is set to enable the initialization software during booting does not mention any ide related thing. Also on the card itself there is no ide related jumper or anything.

What's the card manufacturer and model exactly? There is a chance that you might need to use your soundcard's software with the cdrom driver to detect it. Are the drivers you're using an exact match to your card, or are they for some other card with the same chip (and probably no IDE connector since there is no .sys file)

All I have found is 'KENTECH COMPUTER KJD-MUSIC16'. But haven't founs any drivers for that model and I'm using drivers for a bundle of simillar sound chips. All of them support IDE.

Since we always love to see colour images here, please post a picture of your soundcard. Thanks!

Here you go

Try to google for

Well, most of the stuff I found are malware and/or for other operating systems.

I'm not familiar with the stock drivers for that card. However UNISOUND should support it. UNISOUND - Universal ISA PnP Sound Card Driver for DOS v0.81b
Note that the readme says

Anyway as this
tool is launched after config.sys, if you want CD-ROM support you'll
have to load CD driver (like vide-cdd.sys) with device driver loaders
like DEVLOAD after Unisound IDE port activation.

Maybe that's the issue you're having wit hthe stock drivers as well? That they initialize the card after the cd driver tries to do its thing?

Thanks, will try that. Also the initializator runs before cd driver, so that's not the thing

So combining these two, I assume that you've tried exactly 1 driver from vogondrivers which is for another card with same chip, and it's still a mystery which one.

Try this as an other option, if you haven't already
(I got this from another vogons thread in the past, maybe even a member here assembled this, sorry but not giving proper credit but I don't remember the details)

cwd_dos.zip

I have found some other drivers, but if I want to download them I need to give my phone number or it's starting to download single .exe file with random name, so it smells like a scam, at least for me. Also I have already tried that driver : http://vogonsdrivers.com/getfile.php?fileid=9 … menustate=46,38 . The driver You have linked is a part of the drivers bundle I've tried.

U4 is missing from the soundcard. Does anybody know if the IDE/ATAPI port requires it?
