replacing system

[eegerda]

My motherboard burned up 2 weeks ago and I was force to buy a computer, am planning on adding my two hard drives to the computer I just got. One hard drive contains my root with fedora 7 installed and swap partition (ext3) and the other one my home partition (also ext3). When I boot from fedora 7, will it automatically detect the new hardware (both computers are of the same architecture, p4 2.6 ghz, the old one is an intel 845ge chipset and the new one is SiS651(B)/SiS962L chipset). Will it work or will i have to reinstall fedora 7 ?

Trying it is a good way to find out.

If the kernel panics, you may want to try booting into rescue mode and rebuilding the initrd or re-installing the kernel, maybe turning "kudzu" back on if you've turned it off.

You will probably have to execute 'mkinitrd'. The files /boot/initrd* are ram-disk files that are loaded by grub into ram and these have to include the exact set of drivers needed to boot your system. This primarily means the right disk driver in your case.

*IF* the disk interface is exactly the same driver then you are probably OK (but you may still want to edit /etc/modprobe.conf to fix the enet and audio and such. If the disk interface is different and if you are desperate to save the root file system, then boot the install DVD in 'rescue mode' and then do as it says - at the '#' prompt "cd /mnt/sysimage; chroot .". *Then* execute 'mkinitrd' with the correct parameters, including the correct disk driver.

Personally I'd just re-install the kernel. Backup /root and /etc so you have all your settings and then reinstall "/" and keep /home.

It will mostly work unless you custom compiled a kernel with only the hardware of your old box.

OK, I can't wait until my new system gets here, am going to try it out and post the results, thank you all for your responds

I finally got my system. I put the hard drives in and the kernel panic as it booted, the disk interface from the old motherboard and the new one are different. I got lazy and I just decided to backup my /root and /etc directories and reinstall the system. As I did this I rain into two problems, the first one was the fedora dvd would get stock while booting on rescue mode. It would get stock on loading pata_sis driver. I found a way around this on a thread http://fedoraforum.org/forum/showthr...light=pata_sis I basically passed the nousb argument to the kernel...that solve that problem, I went into rescue mode and copied my configuration to my other hard drive. The second problem I ran into was my new nic Realtek RTL8100B was not found by fedora or any other live cd I tried. I think is a hardware problem since cat /proc/interupts doesn't show my ethernet chipset, I tried messing around with the irqs in the cmos and the didn't do it, so I just put in an old nic i had laying around, works great! After updating yum and the system, I copied all my configuration files, and it all worked, as if I was still using my old system!
