I noticed this link to MSFN over at Driver Heaven today which allows you to install Windows XP unattended with pre SP2 fixes and so forth. MSFN has all the information which you shouldn't miss.
Have you ever wanted a Windows XP CD that would install Windows XP by automatically putting in your name, product key, timezone and regional settings? Followed by silently installing all your favourite applications along with DirectX 9.0a, .Net Framework 1.1 and then all the Pre-SP2 hotfixes, updated drivers, registry tweaks, and a readily patched UXTheme.dll without any user interaction whatsoever? Then this guide will show you how you can do just that!More information @ MSFN
