I read thru the XP clean install guide and searched and I'm having several issues. I started my clean install a couple of days ago based on my experience with my X30. Unfortunately the X60s hasn't been so smooth. I've searched and poked and prodded with moderate success, but no solutions so far.
If you saved the SWTools Folder on the C:\ drive, you can burn it onto a disc and have device manager search the disc for the driver. I'm assuming you have a drive since you've managed to install XP.
Unfortunately I don't have any of the recovery tools. These were previously .gov puters and came with no HDD. I used a X60 docking station's DVD drive to install XP. At the moment, I'm UNinstalling .net framework 4.5 and REinstalling .net framework 3.5 to see if that will allow the power management installation to complete.
