1) Get a DOS bootdisk and put bootprep from XPe on it.
2) I set up my system with the CF card by itself on the primary controller and my DVD and HDD on the secondary controller. Since my slim DVD can only be master, my HDD was slave.
3) Boot up to DOS and run fdisk, then format c:, and finally run bootprep /dc (/dc denotes the c drive, /dd d drive, and so on).
4) Copy the files from your HDD to your CF. I used knoppix to do a copy. Don't just use the DOS copy command because it'll ignore hidden files. Using knoppix it was pretty quick. Originally I tried partimage on knoppix until I realized it wasn't worth the extra steps.
5)Shutdown and remove your HDD. Reboot and it should boot into XP from your CF card. The first time you boot it MAY not load EWF properly. I think this happened for me because I had my HDD still plugged in, but I just shutdown, removed it, rebooted, and EWF was back fine.
