Kernel panic: VFS: Unable to mount root fs on 03:04

I am using a very old PC in which Caldera DOS and Linux has been installed. I get the following error message when booting.
Kernel Panic: VFS: Unable to mount root fs on 03:04.
I have replaced new motherboard recently with same configuration. Does that affect booting and is the mother the reason for this booting error?

Can anybody help for solving this error.....

Do you have another computer?

Then check the grub config at/under /boot/grub2/grub2.config.

When the machine displays the grub menu, press "e" to edit. On the "kernel" line change "root=whatever" to root=/dev/sdx, where x is the partition # of the root filesystem. If you don't know, just try /dev/sda1 and if that doesn't work, try /dev/sda2. If you get it to boot, then fix grub to use it that way. I think the files are in /etc/default/grub.
