Gentoo Installation-changing motherboard/cpu question

wrc1944

Am I correct in thinking that if I wish to upgrade my motherboard and cpu only (using same video/sound cards, modem, cdburner, hard drives, etc), all I need to do is before I install the new board/cpu combo build a new kernel using the current system, only changing the board/cpu configs, and then shutdown, disconnect everything, switch boards, reconnect all the drives and cards, and reboot to the new kernel?

Shouldn't my system just reboot normally, if I choose the new kernel I compiled with the new board/cpu configuration?

I'm virtually certain this will work, but I'd like a confirmation from someone who has actually done it with Linux. I'm on dialup, and reinstalling Gentoo is a real job, as far as time is concerned.

Thanks,
wrc1944

Really depends my friend on how different the motherboards are ... you know ... I have done it theoretically as you've described. However, I used a different distro I think it was redhat and it said oh this hardware has changed would you like to config it. So i just went through a long ass list of hardware changes. You don't even need to recompile your kernel if you dont want to because all the drivers are already there in the gentoo-sources, well damn near....

let me know how it goes ...

Don't forget to check any hardware specific USE flags and CFLAGS in /etc/make.conf as well. If you're drastically changing CPUs, this could have a big effect.

Thanks for the reminders!

coondog- I don't use gentoo-sources, always compile my own 2.6mm kernels as user, so I'd have to make sure I configured the new stuff in.

MasonMouse,
Good reminder about the /etc/make.conf file- I'd basically be upgrading my Athlon-xp 1700 is all, so I'll be OK about that.
