The T60 is a laptop. It only has one hard disk -- so I'm not sure why you were seeing ad0, ad1, ad2 in the past. You shouldn't have been, unless you had 3 hard disks hooked up somehow. The bottom line here is this: absolutely *nothing* requires the device numbering to start at zero. And this is definitely the case. > does fbsd create a uniqe identifier for harddisks in combination with > the motherboard or something like that? where can i dig further into > that issue? It's not really an "issue". Very likely your computer has toggled some BIOS settings. The T60 series has the ability to run the SATA ports in two modes: AHCI, or Enhanced/Compatible. Chances are before the motherboard swap, yours was running in the opposite mode that it is now. I would highly recommend using the AHCI mode. It works quite well with FreeBSD under Intel controllers. Turn AHCI on (if it's not already), and do not mess with it. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
