Hi Guys,

I'm having some strange issues with my build. I have a Compaq Portable 386, with a TI486 SXL-40 running windows 95.

At first I had added a Compaq slimline CD-ROMs using a Sound Blaster ISA card and I got no problems, worked perfectly.

I'm now toying around with a ReelMagic ISA card from Sigma Designs (the same one as this one https://www.ebay.com/itm/Sigma-Designs-ET-700 … rwAAOSwSk5ciAul) - it's basically a soundblaster compatible + IDE CDROM adapter + MPEG-1 decoder card all in one. I've gotten the soundcard part to work, and I also thought I got the CDROM working, but when I try to load images from the CDROM the images are a little distorted (it almost looks like the image is a bit "streaky" with one or two of the lines of the image not lined up with the rest of the image. Video files load the first frame then I get a windows 95 illegal operation error and the video player shuts down.

Text files off the CDROM load up fine both in dos and in windows. EXE's don't seem to work however. In windows I get these messages: A device attached to the system is not functioning, or this program has performed an illegal operation and will be shut down.

Here's the CDROM I'm using, just a generic slimline:

The driver I'm using is one I found on CDGOD ver 5.5 (https://web.archive.org/web/20061102233436/ht … dld/cdgod55.exe) which makes it super easy to test out drivers. The driver that seems to work best so far is CPQIDECD.SYS (My Atapi_CD.sys also worked but it seemed to load images even more corrupted). Originally, with the soundblaster, this CDROM worked flawlessly with SBIDE.SYS.

Does anyone have any idea to why my CDROM won't play nice with the Sigma Designs ISA card? Is there something I'm missing? Are there any switches that I need to set in my config.sys ? 😕

Should I keep trying different drivers?
