Use a normal old FDC cable that has a card edge connector and either untwist or take off and place the primary connector before the twist.

Re: Motherboard is missing 9-pin USB2 header. Easiest solution?
Posted on 2022-02-28, 16:28
It has the 10 pin USB1 header intact, but my case is newer and only has USB 2 and USB 3 ports. USB1.0 and USB2.0 use a 9 pin header to export 2 USB ports USB3.x and higher use more pins If your connector is just labeled USB1 it does not mean it is only USB1.x if your case connectors have more pins, …

I don't know, but since you didn't mention it explicitly I have to ask if you tried another cable. other usual suspects would be driver or indeed some card configuration for which a suitable setup program should be found together with the driver on the original driver disk... 😀

Looks like the ultimateretro photo is of v2.1 and that, to get the lower voltages, requires a VRM module, similar to the one necroware built and made a video about. It's the connecter right of the cpu socket that looks like it's filled with jumpers. The one on imgur seems to be v1.1 and has indeed a …

The two pictures are of the same thing. The legs that go into the capacitor are broken right where they enter the capacitor. I don't know if I could resolder those two broken connections. There are four of these on the card, and they are all marked the same. The pads all look good, it's just the …

Such hardware should always be place in a pyramid of power for several months to let the universe recharge the device with its energy. Intermittent problems are the worst.

some things that popped to mind... Could this 'weak' signal be due to broken or missing decoupling caps ? Is the voltage level the same/similar across the board? for example, I once had a board that was crashing regularly. I though I had to recap the psu which I didn't really feel like. The voltages …
