Devices are identified by a major number and minor number.  This says the
kernel is looking on major 01 minor 01 for a file system....and not finding
one. Usually you fix this by adding a "root=/dev/sda1" (or whatever) kernel
parameter when you boot.  The kernel doesn't "search" for a root file
system....it basically expects it to be where you tell it.
