No.

The basics of the drives differ too much.
IDE (atapi to be more specific) uses a different pinout and signals than say Panasonic or mitsumi.

Only Really old drives do support these protocols, and you'll probably only get 1x or 2x speed drives. Most 4x and up are atapi with regular IDE pinout.

(Interesting thought: a converter to connect a 32x atapi CD-ROM drive to an ancient Panasonic header would be nice)

I need connect a CDROM Drive in a 386SX but i don’t know how 😭

Guessing you have and IDE hard drive in your 386SX set as master.
You can connect the IDE CDROM as slave.

But where?? In the sound card not work. I don’t know where connect it.

The same cable as your hard drive. If you're using a cable with connectors at both ends but not in the middle, get a new cable.

Can i connect other controller card in the motherboard?? I have two hdd

yes, that is possible IF other controller card can be set to secondary IDE port, and other devices on other controller card can either be disabled or set to alternate ports so it does not conflict with your current ports, like floppy, serial, game or parallel.

So primary master and slave are occupied. That leaves some options.

1. Get another IDE channel. Probably the easiest and cheapest route. This does need some understanding about irqs.

Usually a primary IDE channel users irq14. Your BIOS searches this channel for ide channels, if it find one it sets as primary.

If you have a secondary Is DE channel, it most likely uses irq15. This has to be set on the controller card, probably by jumpers.

Lots of controllers won't allow anything other than that irq14, so adding two controllers to irq14 confuses your BIOS and won't allow you to use either one. If the controller supports to set any other (free) irq, you're in luck: these can coexist.

Lots of sounds cards (mostly newer than yours) do support atapi (IDE) as tertiary IDE channel. These not than often out themselves on irq10 so it won't conflict with the primary or secondary IDE channel.

If you don't have a secondary IDE on irq 15 but you do on -say- 10 it's ok. Your favourite driver should be detecting a master drive on this channel.

2. Get a mitsumi, Sony, Panasonic drive that does talk to your sound card. Probably the most expensive and slowest experience.

3. Get SCSI stuff. Not too cheap probably and a bit harder to set up with terminators and I'd numbers.

4. Go parallel. I'm going to set one up some time soon to get a CD-ROM drive connected to my IBM ps/2 machines.

5. Decouple one of your hard drives to make room for the CD-ROM. Definitely ready but probably not your choice.

waterbeesje, FYI, the IRQs are to allow the controllers to signal the CPU, not the other way round. The cpu/system can not use the irqs to detect anything. Primary IDE is on port 0x1F0, secondary normally 0x170. tertiary... whatever the card is configured at and the drivers been told to look at. They even have a dma channel assigned to them on some boards, though that's a whole other rats nest.

I have two hdd and i have another controller to install, they are the same, when i install it, it gives problems. The computer is a 386SX 25Mhz.

Did you read what I wrote in an earlier comment ?

You have to be able to either disable or set to an alternate address the ports on the other controller and you will have to set the IDE controller on the other controller to the secondary IO channel.

From a quick glance at the photo, it does not seem possible with that card. Do you have a manual for it ?

edit: found what looks like the manual https://www.elhvb.com/iocard/tdnservices/m5105.gif
It is not possible to use this card as a secondary IDE controller.

Wooo thx ☺️
I only can connect two IDE. Ok.
