Man was this a process. Thanks to all of the people at MDL for the great tools and info that i used. Sorry about the incomplete and missing links, but my post count was too low to include complete links. It wasnt clear to me at all if a non-OEM home built computer could work with these tools. I read a few posts that indicated it might, but nothing conclusive. I have an MSI Motherboard with AMI BIOS. I decided to start with the DMI Boot CD for Award-AMI-Intel BIOS (Add SLP1.0 w/o modding) method. I used the SATA version just for future needs even though i only had IDE Optical drives. I then followed the guide by ameykelkar (sorry had to remove link) The guide worked to a point, although it wasnt specifically written for my application. I grabbed a fresh copy of Windows XP Professional with Service Pack 3 (x86) - CD VL (English) from the torrent link in that post. I checked the file integrity with the MD5 & SHA1 utility and it all checked out fine. I then installed Windows XP and used a Corporate key i generated with the MSKey4in1 Key Generator. I burnt a copy of the OEMBIOS utility and it came up empty initially. After running the DMI Boot CD for Award-AMI-Intel BIOS and selecting option 2 to tattoo with the AMI/Award for HP. I ran it again after it came up with the HP info and said it should pass activation. I then installed Windows and all of my drivers etc. I thought i might be good to go at this point and tried running Windows update and it failed WGA. So back to the DMI Boot CD for Award-AMI-Intel BIOS (Add SLP1.0 w/o modding) thread and the link to the VLK & OEMBIOS Changer I then downloaded the VLK & OEM BIOS Changer and the HP / Compaq (OEMBIOS.CAT CRC32=CD4E1902) uncompressed BIOS file from (removed link) There were 2 HP OEMBIOS, but only the HP / Compaq link worked. I followed the instructions in the VLK & OEM BIOS changer readme file and im now passing WGA. Maybe i needed to read a little deeper into some of the threads here and i would have answered some of my lingering questions. I hope i made this all clear enough, so that it might benefit someone else. Its still not clear to me if i can create 1 single slipstreamed XP Pro SP3 CD with everything i need for any system. I guess ill read on and see what answers i can come up with.
