Thinkpad will allow people to change personality information, even without supervisor password. Unfortunately, this info is changeable even without supervisor password. This might be more severe than it seems, because, IMHO, setting personality information means flashing bios. I was told personality info is stored in separate page of flash memory, so main BIOS should be safe. Easy setup - HDD tests.
Easy setup is just plain ugly.
It looks like a perfectly safe thing. Well, it will overwrite part of your hard drive without even asking for confirmation. It seems like hard drives come preformated to slightly lower capacity then they really have. The rest is test zone, used for easy setup's rw tests. This one killed 2000 of my inodes 4 times.
