For what it's worth, Thatvietguy is right. If there are no drivers available for your motherboard for XP, then you're not going to be able to use some of the integrated components such as the onboard network adapter without driver support. There are NOT always drivers for every imaginable chipset, be it sound, LAN, graphics, storage controllers, etc., for every motherboard on every OS out there. IF there are no drivers for XP, then you MUST use a newer OS and nothing short of having somebody compile a custom driver is going to solve your problem.
If the manufacturer says "you must use OS "X, Y or Z", then that's what you must do unless there are chipset manufacturer drivers for that particular onboard device/hardware/feature available independent of the motherboard manufacturer. Sometimes that is the case so knowing what manufacturer and network adapter chipset you have may allow you to find an XP compatible driver. Realtek, for example, often offers drivers for some of their hardware chipsets that the manufacturer of the motherboard that is using their chipset does not offer. Getting it from Realtek in cases like that may allow it.
This applies across the board whether it's Intel, Realtek, Qualcomm, Creative labs or whever. But more often than not, if there is no driver for a specific OS listed on the motherboard manufacturers site, you're out of luck. You may simply have to ditch the idea of using it with XP and move on to a newer OS.
