Hello, anyone with a GF5200 Ultra can please post a vbios dump? I'm currently working on a 5200 on which i put 256MB of Samsung TCCC ram, voltage is 2.78V (with TCCC is usually not worth going much higher) running on MSI FX5500 (same reference pcb) bios (i've noticed earlier 5200 bios create weird …

For L1 just put a zero ohm link in its place. The ferrites inline with the signal are pretty much only there for EMI compliance. In fact a quick and effective fix for cards with muddy VGA out (I've done it myself on a couple of ViRGEs) is to jumper the ferrites and remove any caps between the video …

You can easily swap the PCB with a SATA one, you'll find a compatibility table on many sites, for example https://www.data-medics.com/forum/threads/wd- … e-pcb-guide.13/ You'll need to swap/reflash the eeprom on the SATA pcb with your USB one though.

Warning: this post might be considered heresy. Intel-made boards of that period should have a good Analog Devices AC97 codec on them, and the accompanying circuitry/design should also be not bad at all. All the bad things you hear about late 90s and early 00s onboard sound are very true considering …

Hello, just wanted to share what I discovered, a FireGL V3100 can be turned into a Radeon X600 just by moving two resistors on the graphic chip itself This picure is a standard FireGL core: IMG_20231216_150940.jpg You'll see on the bottom right corner there are a few resistors, 3 horizontal ones and …

I'd still use a bigger heatsink if I could. With a Pentium 100 (your P75 seems jumpered to run at 100, as they all did) the regulator it's dissipating about 5W as heat. A Pentium 100 is about 10W, and if you think at the size of a typical Pentium sink, using that STB cooler for 5W seems a little …

Those are more likely to run as this is similar to Prescotts Sorry, I didn't see your post until today. …

I'm pretty sure it's just a standard 15" XGA LVDS 20 pin panel. Disassemble the lid and see what is the panel model. In my experience if the signaling is the same (e.g. LVDS, eDP ecc..) and the pinout matches it will work 99.9 of the time. You should be able to find a used panel or a complete scrap …

These are PCI USB controllers with an active PS/2 to USB adapter soldered on the board, the PS/2 will be presented to the OS as USB HID devices. So (assuming you have a working USB2 stack installed) you need an OS that knows what a HID device is, so Windows 98 onwards.

What I'd do is find a PS/2 extension, or a salvage a cable from a scrap device and depending on how your kb is made crimp a new connector on the pcb side of the cable (usually …

The 80-wire-40(39)-pin connectors have thinner "teeth" (how do you call, the pointy bit of the pin that displaces the insulation) to deal with the thinner conductors, and have an additional blade between the two rows of pins that grounds every 2nd wire in the ribbon, and also pin 34, which is how …

An AM2 bracket could be made to fit maybe? Or get a heatsink that will overlap the holes (some weird thing from a major OEM would be your best bet I'd guess. I recall Fujitsu used something that could work), drill and tap it and then fit it with some through bolts?
