Hello,
i heard that we can't run windows xp profession on core i3.Is that correct.please suggest me if is there any way to install windows xp professional on core i3 because it is needed.i am not able to run my software on windows 7.its required window xp professional. thanks in advance
The correct answer is YES you can almost always run XP on newer machines, including I3.
The problem most people have is they try to replace 7 with XP on a machine from a big OEM and run into a problem on startup because they are set to use AHCI by default, and XP doesn't recognize AHCI natively. This leads to install issues. Which leads to novices thinking it doesn't work with I3, I5, ect. I'm sure its an issue with homebrew as well, but those guys tend to be more skilled at resolving such problems.
The solution to that particular problem is switch it from AHCI to IDE in the bios, or install the XP chipset driver on startup by slipstreaming or using a seperate driver disk. One of these will resolve the AHCI issue on install.
Its also worth noting that Drivers, while usually available, can be hard to find for some big OEM machines. Best place to look if the OEM doesn't offer XP drivers is the chipset manufacturer website.
This is mostly an issue with laptops. For example, NVIDIA no longer offers XP drivers for laptop parts, but does for desktop. But there are ways to work around that too.
I have yet to run into a machine I can't convert to XP, but I have seen a few laptops that took a lot of work and research.
