Whilst digging through some old parts I came upon my old SB pro 2 which has the onboard ide controller and included matsushita 2x cd-rom drive. Well I install the card into a free ISA slot, plug in the cd-rom drive into the cards on-board controller and install the drivers. But whilst mscdex seems to detect the drive and load the drivers, and cd to drive D: does not result in an immediate I/O failure, upon trying to DIR the drive it fails with the a/f/r error. I go into the setupcd program and insert a music cd as instructed. I hear the drive spin up for a few seconds then the test fails. Im wondering if I have a DMA or IRQ conflict, or both. Can someone point me to the default jumper settings for a sound blaster pro 2? Model 1600 I think. Once I set the jumpers correctly on the card, and if that does not solve it, then what should I do next? Thanks in advance.

If your Sound Blaster Pro 2.0 a CT-1600 card, it does not have an IDE interface. It has the Panasonic interface, and it doesn't use IRQs or DMAs. It is either set to use I/O ports in the 220-23F or 240-25F range, depending on the SB Pro 2 jumper. Make sure your drive is meant for that interface, look up the model number to figure it out.

If the drive uses the interface that the card supports, then make sure you have loaded the drive's device driver correctly.

I'm using an ide cable, and I believe the drivers are installed correctly. MSCDEX.exe loads the driver. Sbcd.sys the device is cd1001 I think. I'm worried the drive itself may be damaged but I'm not giving up. Also the drive has jumper positions 0,1,2,3 on the back.

What Great Hierophant is trying to say, is that although the pinout on the SB Pro2 is similar to IDE, it isn't actually IDE. It's a proprietary interface for Panasonic CD-ROM drives. If your device is an IDE unit, it isn't going to work on that interface. Back in those days, most CD-ROM drives used one of several proprietary interfaces, and neither of those were IDE, although they used the same 40-pin connector.

I am not sure an IDE cable works. You should also check which SYS you are using to enable the CD-ROM.

I think the cable is mounted on the wrong direction.

On the card the red pin 1 needs to connecting on pin 40 (last pin). So the cables ends on the back of the card.

In the drive in needs pin 1 on pin 1 on the driver..

The IDE looks the same as the drive cable, but it works different.

A standard 40-pin IDE ribbon cable will work to connect drive to card, but as Robin4 said, make sure pin 1 is connected to pin 1. Use the red-colored wire to make sure. If you have a cable with notched connectors, you may need to cut or file away the notch.

Now its not noticing the card. 🙁 says cd-rom or controller card failed to initialize.

Ok so now the sound card isn't recognized.

Fixed the sound card. Now, for pin one, the red tracer on the cable goes tiwards the power plug (molex) on the cd-rom drive and on the card its on the last pin. Correct?

I dont know if its tiwards the power plug, but every pin is clearly marked which is pin 1 and which is pin 40.. on the drive and on the card. If it was the IDE standard, you just need connect the cable both on pin 1 with that red stripe.

As i said IDE cable works different then that proprietary type of cable.. Best is to take a cable with only the two connectors on both ends.
Ill try to upload some photos.

This is the way to connecting the drive:

And this on the soundcard (the soundcard iam using is a SB AWE32 CT3900)

Tip on the CT3900 soundcard there is no plastic bracket around these cd-rom connector, but the SBPRO2 CT1600 actually have one, so you can twist the cable from pin 1 (red stripe) to pin 40 on the card)
Then you have to remove the notch on the connector from the cable that goes on the soundcard.

So pin 1 on the card is near the ram simm. Pin 40 is on the downside of the sound card.. So you need to connect pin 1 on the cable to pin 40 on the soundcard.. Otherwise the interface wont regonize the cd-rom drive..

If you know how it works, then the best it to make a right cable for your soundcard / cd-rom kit.

Can you tell me which brand / type cd-rom you want to use..

You can only attach panasonic drives to that connector, mitsumi ect dont work.

Ok so I took apart the drive and turned out that the raid motor for the laser has siezed. I oiled and unstuck the motor with the worm drive, but it seems as if the actual motor that spins the disc is siezed also. Ill have to fix that.
