First I suggest you install Windows XP but you need the Windows installation CD and the product installation code.
Second, the USB ports and therefore the CD ROM drive will not work until Windows XP has been installed, unless the BIOS supports the USB ports and you can make the USB port/CD ROM as the first boot device.
After installing Windows you need to install the ThinkPad's device drivers.
The same model ThinkPadcan have different types of network, video and audio drivers and unless youknow exactly which one is installed in your ThinkPad, you need to download allthe drivers and install each driver until you find the right driver.
When you download thedrivers, write down the device driver and it's file name so you have a recordof which driver you are installing and which directory the unzipped files arelocated on your hard drive.
Go to the IBM/Lenovo WEBsite - support/download page and download the latest Windows XP or Vista devicedrivers for your model computer, Use this link: -
You can download thevarious drivers and then you click on and run the various driver files, theywill then unzip and expand into a sub folder on C:\drivers Then install thevarious drivers from this folder (run the set-up file).
