The *only* function of DOS in the DOS version is to 
boot the kernel (using loadlin.exe).  There are several 
other methods (eg lilo) to boot the kernel which are 
just as effective.  DOS is just a convenient way to 
boot Linux for users of old PCs (which often have DOS 
installed already).

There are just two steps to running Linux:
  (1) start the kernel
  (2) tell the kernel where the root filesystem is

If you look at BOOT.BAT in BasicLinux:
--------------------------------------------------
loadlin zimage root=/dev/loop0 initrd=initfs.gz rw
--------------------------------------------------
The loadlin command boots the kernel (zimage) and tells it 
to run /dev/loop0 as a read-write filesystem.  The initrd
puts fs.img into /dev/loop0.

Cheers,
Steven
