From reading the boot up process I don't think I don't think there should be a problem, but I too will be experimenting with this. I just ordered a new mobo and CPU (nothing cutting edge - a 1.6 AMD) to replace my old dual 333mhz system, and that's exactly what I planned to do. Reboot using the GENERIC kernel. The only time this is important is when you go from a SMP mobo to a single cpu mobo. A system running an SMP kernel paniced when I tried this. The GENERIC kernel worked just fine. Commenting out the SMP features and rebuilding the kernel worked on the first boot. If you use cvsup to upgrade your systems, you want to have a current GENERIC before you try the upgrade. BTW, assuming you have a reasonably fast Internet connection, rebuilding the kernel is nothing to be that scared of. There's plenty of great resources, and as long as you know how to select which kernel at boot time, and you save your currently working one with a known name, you can always get back up and running. I start out by moving HDs and cables into the new system. It was never a problem except when I downgraded a system from 2-slow coppermines SMP kernel to a much faster AMD 1600+ XP. I moved the SMP mobo into a slower machine but only used 1 cpu. It wasn't a problem there either. Two weeks ago that mobo finally died and I upgraded from a VP6 to an Gigabyte GA-7VAXP. Since both of them had onboard raid controllers, that wasn't a problem. The boot maintained the same order and I didn't have to worry about what was in /etc/fstab. For what I use the systems for, raid was never faster and I just use them as additional controllers with an HD on each. Just to change subject a bit, one thing a lot of the resources say when you want to select which kernel to boot is to hit some key besides enter at the prompt. Then, at the "ok" prompt, just say "boot theotherkernel". But when I try this, I get a "Kernel has already been loaded" message. I finally figured out to do an "unload kernel" to get around this, but I was wondering why I had to do this? It depends on when you interrupt the boot. When it gets to the twirling cursor, you have loaded kernel and as you found out, you have to unload the old kernel first. If you interupt at the "-" prompt, you can say boot GENERIC but then some processes such as top won't work.

RE: Upgrading Computer
Its what I said already - moving HD and NIC to a new machine is usually all there is to do unless your new cpu etc has all its interrupts spoken for or something.

RE: Upgrading Computer
What about going to a new cpu and motherboard with the same nic and hd? I am in the same situation except that I want to move to different hardware.

You might need to edit the /etc/fstab. This will most likely happen when changing the IDE channel. What ever you do, FFS do a backup at least of /etc and have the Fixit-CD by hand!
