[-S

[-T

DESCRIPTION
The
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.
