Solve : Theoretical motherboard modification?

1.	Solve : Theoretical motherboard modification?
Answer» I have a motherboard that has some holes/solder points where additional components could have been installed, but for some reason, during the manufacturing process, were not. In my case, one of these components is a PCI express slot. THEORETICALLY, if I were to solder a PCI express slot ONTO the motherboard, would it just work or would the BIOS not likely support it? My guess is that the BIOS is probably the same as the BIOS for the board which came with a PCIe slot (I am assuming there is one) so I think it would work. Am I right? This is just theoretical. I don't plan on actually adding a PCIe slot because it would be way too time consuming.If they out the connector, they would also leave out the chip that goes with nit. Do you have the model number of the mobo? Most likely it has a crippled chip set or is lacking another chip. Just a guess. They started making some boards and they discovered the express slot was not working right. So they ran some early versions of the board without the connector and sold it as a board not having that feature. They give it a different model number. Just a guess. Anybody out there would works in motherboard production please come here am tell US that never happens. Quote from: Linux711 Theoretically, if I were to solder a PCI express slot onto the motherboard, would it just work Theoretically, I think probably not. Probably the motherboard maker made the board that way to aim for a particular price point, possibly to use up chipsets that failed on PCI Express but passed everywhere else. Or maybe the boards were the partly functional items. Maybe the combination was the problem. Margins are tight in that business, and cents matter. I doubt the BIOS would be the same as another model with PCI-E present. In any case it's the chipset, not the BIOS that matters here. (No good having code in the BIOS to control hardware that isn't there). Also I doubt you could solder a slot onto a multilayer motherboard with a hand soldering iron. Even if you could get in between the layers you'd damage the board. Components are mounted all at once with solder PASTE where necessary and then they are SOLDERED at once using a wave soldering technique where the board is suspended a very short distance above a bath of molten solder and a wave is made to run across the surface of the solder in the bath, which makes all the solder joints in one pass. Also you don't know what other (surface mounting, hard to solder with an iron) components such as decoupling capacitors, voltage regulators, resisistors, etc, have been left out. (Like I said, cents matter).

Theoretically, I think probably not. Probably the motherboard maker made the board that way to aim for a particular price point, possibly to use up chipsets that failed on PCI Express but passed everywhere else. Or maybe the boards were the partly functional items. Maybe the combination was the problem. Margins are tight in that business, and cents matter.
