The Kernel gets this info at compile-time, it is only overridable by a
kernel-argument ("root=..."), this is what lilo does.

If you want to change this so called "root-device" inside the kernel,
you should take a look at the tool "rdev" and its man-page.

I had the same problem some time ago as i wanted to build a
boot-diskette without any loader like lilo or loadlin, etc.

As the kernel contains an i386 bootsector, it should be able to boot
itself if it is copied on a diskette and the bios jumps to its
begin...but then you cannot say the kernel, where the root-filesystem
is, so you have to change the root-device inside the compiled kernel,
and this does "rdev". 

Unfortunately, it did not work for me, so i switched back to
loadlin...:-((...but i tried it only one time, perhaps *i* made a
mistake and not the tool...:-)

Solong..

Microsoft isn't the answer.
Microsoft is the question, and the answer is NO.
