Look in France or Canada, you shouldnt have that hard of a time finding a French version of Windows.
I would also agree with Canterwood that you are going to need more RAM if you want to run XP, if you are going to be doing really simple stuff (like web-browsing) 128MB would be enough, however if you are going to do much more I would reccomend 256+. A 350mhz P2 should run XP fine (again for the basic type of stuff) but we dont know what kind of P2 he has so I would reccomend this, if your P2 is at least 300Mhz you should be in the clear. In any case 98 would run just fine.
