I would expect to see the wizard here, since you're manually rescanning for hardware. No wizard in mini-setup mode on first boot. There is a line in Sysprep.INF that should reflect your DriverPath reg value, relative from the root of the boot drive. Both must match. So for /HKLM/.../DevicePath: "%SystemRoot%\drivers\network;%SystemRoot%\drivers\video", but for Sysprep.INF: "drivers/network;drivers/video...". Question: if you click thru the wizard, does Windows install the drivers normally, or does it give any warnings or errors?
