With my shiny new TechNet Standard subscription in hand, my first target was my beloved ThinkPad X40. You'll remember I replaced the 1.8" hard drive with a KingSpec solid state drive.
I maxed out the memory at 1.5GB with a $19 DIMM from 5R Processors.
I built a USB drive with Windows 7 Pro and Office 2003 and Office 2010.
I booted the USB drive and Windows 7 was installed in about 30 minutes.
Device Manager didn't look so good. Lots of yellow exclamation marks! I started Googling them one by one but came across one suggestion that was just too simple: Run Windows Update. Duh!
Since one of the exclamation marks was the wireless adapter, I plugged in an Ethernet cable and fired up Windows Update.
The video card wasn't recognized. Back to Google. It wasn't so simple this time. The Intel chipset the X40 uses simply doesn't have Windows 7 drivers.
There were a couple of people who claimed they had overcome this but there were almost always comments that that solution hadn't worked.
I finally took the simplest solution with no dissenters and tried it.
Now I have a 2.7lb. sub-notebook running Windows 7 with all the features working fine.
Next? A ThinkPad T42.
