Topic: motherboard + esmith upgrade

[Arby Edi]

I'm running 5.1.2 on a computer whcih cannot go any faster.  I'm going to upgrade the motherboard to take advatange of AMD's chips and DDR memory from my current intel p3..  Let's not get into a discussion o that.   My question is, can I just toss in a new motherboard even though it'll have a different chipset and builtin video/sound/lan (the lan I'll disabled and use my existing card) without any major problems.  I understand to get the video and sound to work I may need to load up drivers (the video maybe not since the stsem is console only and sound I don't need).  

Please help help help.

Well I went ahead and just did it.  Everything is fine, the only FIALED I got was on the USB startup whcih is fine since I dont' using the USB ports.

Arby,

I just think that without reinstall you´re loosing performance because Linux isn´t fine tuned to your hardware.
Maybe later you could do TWO set of backup and reinstall (and try SME 5.5!)

Thanks by report that this kind of CRAZY ACT is possible! (just kidding!)

I was running SME 5.5 on a P1-200 and a few weeks later I put the hard disk in a P2-300@337 and everything wokred just fine. No probs at all.

Molski,

You don´t any problems but your Linux still think it´s working on a P1. So his kernel and internal programs are optimized to Pentium 1 not Pentium 2.
You might be paying the price in performance!

Anyone else agree with me?

That makes sense to me actually.  I upgrtaded from a p3-700 to an AMD athlon 1700 XP. (like it makes a real diff).  Anyway, assuming there are changes that the OS will make if I had a fresh install....WHEN I upgrade to 5.5, will that perform that needed changes to my system or will I really need to do a fresh install of 5.5??  

Or I could just be sitting at one of those, if it ain't broke...type of things.

I really don´t know! When Linux is installed it configure his kernel to optimum performance based on CPU. So if you change CPU type to better one you are not using all linux features to this kernel. And you change CPU type to worst than installed it must don´t work at all.

But what it does when upgrading?

Someone else has a tip?

Thanks!

I tried this act of craziness, and now my system boots okay, but the NICs aren't connecting to either the internal network, or the external. I'd reinstall in a second if I didn't think it was going to wipe my drive clean. Does anyone know how to re-install e-smith over an existing installation so that it doesn't wipe all the data on the disk? Any suggestions?
