Hi there guys. I am new to the forum. I have a Lenovo N200 and I want to downgrade to XP. I've been searching all over the net but cant seem to find the answers I am looking for. Can someone PLEEEEEASE assist: 1. Can I just do the downgrade by downloading the Intel Matrix Storage driver and putting it on a stiffy (external USB stiff drive) and press F6 before the installation to install the SATA driver? I have read that some people have problems with this method. 2. Can a flash drive be used instead of a USB stiffy drive? Here are the instructions on the Lenovo site, but do they work for downgrading from Vista Home Basic? Installation instructions On another system 1. On another system, extract this package onto the hard drive. 2. Connect a USB-Floppy Disk drive or USB-Hard disk drive. 3. Specify f6flpy32.exe with the full path name where you extracted the package in the step 1, and double-click. On target system 1. Connect a USB-Floppy Disk driver or USB-Harddisk drive that you used in the above steps on the target system. 2. Restart with Windows XP SP2 Operating System CD and press F6.
