Sony's PCV-2xx systems do indeed use that motherboard...

Have access to any software or drivers by any chance? Do I need to do anything to get OPL4 working?

I'm just using the Intel-provided drivers (for Windows 95), which I've put in an archive here, if that's at all helpful:

The only Sony-specific software that I'm aware of would be the modified version of the "ATi Player" video application, which you won't need to worry about.

Nothing that you know of for the onboard OPL4?

Not with my setup at least. That is, the YMF721 behaves as an external/standalone MIDI synthesizer (like a Wave Blaster on an SB16), and responds to any playback directed at the YMF715E/OPL3-SA's MPU port.

Good to know. I will try to mess around with it more tonight after work.

So I finally got a chance to work more with the system. Does detect and use both OPL4 chips in windows. However the MIDI playback will slow down and change tempo if you move the mouse or around on the keyboard.

Presume there is some kind of IRQ or DMA conflict??? Happens inside Win98 and outside in DOS.

Just a standard Intel 440LX board, my Micron has one identical to this. I believe the yamaha chips were an option from intel on those boards for the manufactures to decide on.

I have seen that board with the yamaha chips from Micron, Dell and Gateway (Not 100% positive on Gateway) machines as well. Sometimes you would find the 715 chip and not the 721 and other times with both (most the time with neither). I didnt not know they had those in Sony machines but does not surprise me.

I think I'm just using the drivers that came on the Micron disks

I haven't experienced this myself, but one reference suggests disabling "Legacy USB Support" in the BIOS as a possible solution, if currently enabled.

Superb news. That was definitely it. Working well within system. Now I just need to figure out why certain games are not saving their music settings. Raptor for example will not see any music device and keep resetting to GUS after exit saving and re entering the setup.

Hi Vanessaira. Here it is the board you own, AL440LX. You will find manual and other info in the downloads tab.
Because your variant also has YMF we kindly ask you to contribute with a photo (see bottom of the page). In the meantime we'll put the Sony OEM information there.

Absolutely!

My friend retrobee has already submitted a few boards on my behalf there on The Retro Web discord. I will upload it when I can.
