The laptop model is IBM Thinkpad T43. That hda to sda looks funny. I didn't know the T43 has a SCSI (which I'm pretty sure it doesn't). > > Any ideia?

When I went from 2.4 to 2.6 I just used aptitude (or apt-get) to get the 2.6 kernel first, and let the package manager make all the necessary changes for me. I also usually don't use an initrd and just compile in the drivers for my ide and filesystems. -- Steve
