hi, i just got a new hp notebook, and after using vista for about 2 hours i decided to downgrade to xp pro. My first problem was that i couldn't install it because i have a sata hd, and xp does not recognize sata hard drives during installation, so i disabled native sata, which got me around that, however when i try to reenable it my computer can't start up... i was doing some research online and read that enabling native sata allows the hd to run more efficiently and just better overall. I just want some opinions as to how much of an effect this will have. Second was the problems i had trying to find the drivers for my computer. HP's lack of drivers for his model (dv9207us) was frustrating, i think they had maybe 3 drivers for windows xp... so i ended up having to use drivers from other computers. I checked the hardware on the computers and they looked to be similar if not the same, and in the end i got rid of all the annoying question marks. One thing i couldn't get rid of was a "SM Bus driver" i honestly looked for hours, and came across a page somewhere that said something about sm bus being related to the chipset. So i found online that the chipset i had was from nvidia, i downloaded it but the yellow mark was still there, then i downloaded an intel chipset driver and that fixed the problem, so after all that, what i want to know is that will installing an intel chipset driver for my nvidia chipset have any harmful effects? Or lag the computer capabilities? Also all i could find was the VIDEO chipset was nvidia, but i couldn't find anything about just a "chipset", are they the same or two different things? Sorry for this insanely long post, but any help would be greatly appreciated, cause right now i'm completely out of ideas.
