Sorry my late response, I was out of office because summer vacation. GreenMachine, Thank you for your warm welcome. Vel Straty, I use XPCREATE for creating OEM driver slipstreaming. I have Rioworks HDAMC mobo, and failed to install 3K because the OEM driver (SI3114) was not installed from FD. Don't know why, I tried almost everything like : memory change older or the latest driver single or dual Opteron 244 all the same. That was my start point and I finally found this forum. The original XPCREATE.cmd didn't work for me then I hacked it myself. (I didn't check your articles at that time) Also I didn't care XPCTHLIST.txt because I don't care Hotfixes at all. I focused OEM driver only. Now I could successfully slipstream OEM driver to 3K CD, and it works for me. I can try XP Japanese with Hotfixes, with your XPCTHLIST.txt. Then I can tell you how does it work. Thank you guys.
