mdsetimage command copies the disk image specified
  by image into the memory disk storage area in
  kernel. The file system present in
  image will typically be used by the kernel as the root
  file system.
To recognize kernel executable format, the
    -b flag specifies BFD name of kernel.
The -I and -S
    flags specify the symbol names of image and size of memory disk drivers
    respectively.
For a.out kernels only, the -T flag
    specifies the starting address of kernel text. This flag is ignored for
    other kernel executable formats.
If the -s flags is given,
    mdsetimage will write back the actual disk image
    size back into kernel.
If the -v flag is given,
    mdsetimage will print out status information as it
    is copying the image.
If the -x flag is given,
    mdsetimage will extract the disk image from
    kernel into the file image. This
    is the opposite of the default behavior.
