I have this intel DX250, with a heatsink attached with a latch on opposing sides of the CPU. How would you safely remove this? I am planning on using it on a different CPU. Do i try to get some sort of tool in between the latches and the CPU? Do I just try to pull it off? Filename _DSC1977.jpg File …

It seems i have the same one. It is a Socket 3 board, i'm using an i486DX4-100. I noticed you are running with S1, S2, S3 and S4 open, which according to the print on the board would give 5 Volts. Aren't all DX4 in the 3.5 V range? Is your DX4 fine with the higher voltage? I have a DX2-50 on mine, …

Wanted to post an update since I have somewhat figured out the cause of the audio problems (6 months later). This was not a problem with the audio card, but rather an issue with the motherboard or how the motherboard interacts with the CPU. The CPU I use is an Intel 486 DX2 66, specifically the …

Not sure how to set Low/High DMA, I can only set the single value. 1 and 3 produces sound, but with the distortion, 5 doesn't work at all for some reason. I know sound blasters have the ability to set Low and High, but not sure I can do that. Also tried various port and irq settings again with the …

I have tried DMA 1, but not the others, so I'll give that a shot tonight. Do you know how to disable the wavetable? The installer just asks what port I want it on. Is there a port that disables it?

Thanks for the suggestions. I changed the jumpers as suggested and it didn't solve the issue. I think the change worked as intended, as sound is a lot more quiet now at the same master volume setting. I also tried closing the three jumpers in the middle of the board, to no avail. It definitely seems …

I have an ESS AudioDrive with an ES1868F chip that I am using in a 486 dx2 66 build, with dos 6.22. This is a great card overall and works really well in most games However, I am experiencing severe glitchy noise in some games, to the point of them being unplayable. To be clear, the audio works, it …

I have a es1868f in the 6.22 486 dx2 66 I'm building. It works fine in most cases, but I'm having an issue with terrible loud glitchy noise in a few games. For instance x-com/ufo and psycho pinball are unplayable because of this. I made a short video showing this in action: https://youtu.be/ …

So this is interesting. I just won an auction on eBay with the same motherboard, and exactly the same description and images. I found this thread trying to figure out what this board is. I wonder if I have been duped. Maybe the seller just has a bunch of these around and is using the same pictures. …
