VFS: Unable to mount root device 08:07

[B.Rodriguez]

    I recently compliled a new kerlel for the first time (2.0.34 to
2.2.12), after fooling with my partitions and where Debian was located.
At boot time I get the message  VFS: Unable to mount root device 08:07,
how I have no trouble booting it from my debian CD. Where do i begin?
