Hello, for my all in one WinXP/Win7/Win10 machine i opted for a GA-P55-UD3 motherboard, why: - it has SATA, IDE, FDD, Serial, Parallel, PCI and PCI-E slots and support for Xeon X3480. Now, because i like to make things work in ways that they were not suppose to and based on the fact that the memory …

Red and black can be soldered permanently, you can use the 'on the way' method for the rest of the signals, clock and data. You didn't followed the instructions, i can see from the start that the red and black wire are not connected ok on the male minidin7 (plug that goes in to the computer). Use …

Socket 754 Sempron3100+Gigabyte K8VT800M can be a great combo for win98 and dos, because unlocked socket 462 cpus/mobos are harder to find: The good: cheap, still easy to find, works with setmul 4-9(800-1800mhz), l1 cache can be disabled, ddr speed can be lowered, HT speed can be lowered (for ms-dos …

Are the white side tabs broken? Those can be replaced separately (can get them from a dead motherboard), you don't have to replace the whole socket.

Anyway I take some minutes to study and understand the logic behind your post of soldering instructions and I have fully understood now. We know where the +5v are on both connectors, we know where GND are too. The thing is to search correctly where DATA are and where CLOCK are in the 7pin minidin …

I used a numbering of the pins that's easier to understand/work with, but if you want to count right and left i have nothing against it :). Let's analyse it, pin 4 in your picture means pin 5 which is 5v in both cases (because you gave me in this picture the pin out of the female ps2 connector from …

Good, let me know if you need any clarifications. So, these are the connectors opened completely. I put two images. I think that the image you gave me before with the pinout was wrong, I cannot find on these adaptors, they are different. Please tell me what to do , and please give me the pinout …

Those are filtering/decoupling caps, cpu should work even without them but can have some degree of flakiness in operation, depending on how good/bad the motherboard is. BEST OPTION IS TO RETURN IT, but cost is a element also, if you have to pay for returning the product, it might be cheaper (for me …

On a BX chipset, slim chances of 'usb mouse support', those boards tend to have only(at least the ones i had) usb keyboard support no matter the naming of the feature.

I think the caps are failing, when they are somehow bad and the board was not powered for a long time, they need some 'warm up' time.

So, i see it very complicated and need a discrete amount of time (that i not have now), i’m store this for fiture use, or if anyone want this board for test (considering his rarity)… Is it the K7S5A? If so it's anything but rare, it was for over a year the cheapest Socket A motherboard you could …

SiS 735 supports DDMA, so shouldn't that work with the Solo too? 1GHz Duron is pretty fast so you might need to employ some slowdown methods for many older games. "Unknown" board with that chipset sounds suspiciously like an ECS K7S5A / PC Chips M830. The former has a black/brown PCB, the latter a …

For Ess Solo 1, ms-dos in TDMA mode, you need a VIA chipset motherboard (any socket) with a vt8233-vt8237 southbridge (that means socket A,s754 s939, sAM2, s478 and lga775). You need to find the 'right' slot, pci slots tend to share resources with other integrated devices (usb, onboard lan/sound) so …
