Hi,
I bought a new machine Pentium 4 3,8Ghz SMP , with 1GB RAM, my system is running in a P3 866 Mhz, with two harddisk IDE. I caught the record of the P3 and placed in the P4, but it is appearing the following error:
VFS: Cannot open root device "LABEL=/" or 00:00 Please append a correct "root=" boot option Kernel panic: VFS: Unable to mount root fs on 00:00
My fstab and df command # df -k Sistema de Arquivo 1K-blocos Usad Dispon. Uso%Montado em /dev/hda2 19196432 7163720 11057568 40% / /dev/hda1 77750 14511 59225 20% /boot none 386244 0 386244 0% /dev/shm /dev/hdc2 77229604 13542252 59764280 19% /home

I can make this type of change? Cheers, Clóvis

Something is looking for a disk label of '/', either label the partition ( from the df -k listing possibly /dev/hda2) or change the fs tab to mount the partition by name rather than label.
Man e2fslabel

Looks like grub is trying to access the root= device by the label, and it may not be labeled.
Try modifying /boot/grub/grub.conf to have the kernel line mount the device by name. The same change will likely be needed in /etc/fstab
