I like this website: http://www.theeldergeek.com/xp_pro_i..._-_graphic.htm
you can also select text version by clicking on the clean install windows xp pro text version on the left side of the screen.
you may also want to slipstream SP2 into windows xp pro (if it isn't already sp2) by creating a disc. the website also shows you how to do that.
if you are clean installing on 700m, just know that windows xp will not pick up the following devices: integrated graphics, intel wireless, LAN, modem, soundcard, and SD slot.
it will pick up the rest, but there are a few updates to the drivers you have on your resource disc listed on Dell's website. there is also the other software. just choose what you need. then after you've installed all those drivers windows update will pick show new driver for the modem and I think the LAN.
you can always just update the files from dell after you install from resource disc, but I always like to just install one thing. The one thing you will have to do though is install the LAN driver to connect to the internet unless you download all the files onto a separate disc first.
there is a windows xp speedstep fix which i installed, but i don't know if it is doing anything. You may also want to download speedswitchxp which i've found improves battery performance as well as allows you to configure power resources.http://www.diefer.de/speedswitchxp/
hope this helps.
