Got my 386SX laptop out for the first time in ages. I noticed some of the paint on the bottom bubbling, so I scraped it away and saw green corrosion/acid underneath. Turns out it had a CMOS battery made from 4x AAA NiCD cells that had leaked and gone through the plastic. Luckily the motherboard …

Photo stolen from someone else on this forum (badmojo)... This was the case that my first computer came in, a 386 SX 33. I'd pay far too much if I ever found one for sale to rebuild the computer again.

But I am sure you can do that with a DOS-based BIOS Setup program, there are plenty. Do you have any suggestions for any? I've never heard of such a thing. Otherwise I guess I could try dumping the BIOS chips and trying to manually edit in the settings... Would prefer to avoid going down that path …

I have this CTE-2000B motherboard. Love the side by side AT power connectors. Whoever thought that was a good idea... rsz_img_20190112_230238.jpg It uses an Award BIOS. It seems to have the ability to enter the CHS settings manually for the hard drive, but I can't for the life of me work out how to …

I have a D815EEA2 which doesn't POST with a Tualatin. I've flashed every single BIOS version available and none of them worked. It does work fine with Coppermine though. Apparently it's D815EEA2U which has Tualatin support.

Well, I fixed it. I replaced the crystal with a new 20MHz one and now the sound output is perfect. The old crystal must have become out of spec and was running the card at too low of a clock speed or something. The thread linked further up says that the crystal should be 19.7568 MHz (the markings on …

Yeah, I've reseated and cleaned all the contacts on the memory. I also tried with just a couple of them installed in case some are dead but that made no difference. After re-watching the video, I think I was right originally that it's slow, not just reduced pitch. Some of the sounds are so slow that …

Here's a recording of Doom: https://www.youtube.com/watch?v=QaNuXontLIs I wasn't able to find the driver debug section in Impulse Tracker. Do you know where it's hidden? The settings automatically chosen by the Ultrasound drivers are ULTRASND=260,1,1,7,5 which means it's using DMA 1 for playback.

I have no idea if all GF1 chips are interchangeable, I do hope that isn't the problem. Yeah, I'm hoping that's not the problem. Apparently both ICS1614 and ICS11614 are used as GF1 chips. Both of them are used on cards which otherwise appear to be the same so I have no idea if there's any …

I replaced the GF1 chip which fixed the problem and got it working again, but it still has another issue. Whilst sound effects …

Still the best of the original cards. Only Keropi's clone gives it a run for it's money.

The battery has leaked unfortunately, but I think it may have just been recently. I can't see any corrosion, only the liquid itself still on the motherboard. Hopefully after cleaning it up it'll come to life. Otherwise everything is pretty much spotless inside. Looks like it was fairly highly …

Is there any way that I could identify the specific RAM chip that's failed, so that one day I could potentially have it replaced? Or maybe it's better to just replace them all, because if one died, maybe the others aren't far behind... What about flashing it with a BIOS to disable one of the GPUs, …

But even outside 3dfx. Hundreds of GF4 MX for a couple of dollars each. 1400MHz Tuallys for a few dollars, 1000MHz Coppermines for about $1.50, slower Pentium IIIs for even less. Hundreds of them. Didn't see too many Pentium IIs, but heaps of Pentium I and 486s which were more expensive. Lots of …
