Hello Group. My first reply here in the MSFN Forum. Yeah! @Bâshrat the Sneaky I have probed your LAN Driver Pack. It's very nice. Thank's for your good work. But i have Problem with the Marvell LAN Driver. So when the system first boot up, the driver is recognized by Windows XP correctly. I see that the driver is not signed, but it doesn't matter because the winnt.sif has the line DriverSigningPolicy = Ignore. But when i run the Tool Sysprep after, and the System boots up for the user, the driver is thrown away from Windows XP. I think it has to do with non-signed driver. Can anybody confirm that ? For the second pc system with a signed driver in the driver pack (sis900), Windows don't throw the driver away. The Problem is that Sysprep always set the DriverSigningPolicy at minimum of level 'warn', if sysprep is launched. Greetz kyor
