First of all, thanks to the quick answers, my installation runs pretty smooth now, except for a little problem with my software installation in install.cmd. As to the certified drivers: I've already thought of that, even if I wasn't sure, especially after the installation accepts certain drivers like the chipset and it doesn't except others the audio/LAN drivers, even if they belong to the same installation package. What really surprised me was that the XP installation accepts the SATA driver, but after the Installation is completed, my System Manager says that there is a problem with the installed driver ( ! mark), so install it right again (from the same directory) and, surprise, surprise, the system accepts the driver without problems. I think I'll have to find a way to install the Mainboard drivers by install.cmd, so i have to figure out how to do a silent install with nforce drivers. Ok. New Question: I've just downloaded the newest WHQL certified NForce driver, and (as mine wasn't quite the most recent) I just installed and stumbled across the following file setup.iss in the folder where the driver components were extracted. Is it possible to install the complete driver package using the setup.iss for a silent install? Because then I could just load the accepted driver components during XP setup, and on the first logon, i could install the whole driver package including e.g. the control panel with a silent install using install.cmd. This is the setup.iss I think it is a bit small for a complete driver package... anyway, I'll try tomorrow. If anyone can help me..... PLZ
