NAME
mdsetimage —
set kernel RAM disk image
SYNOPSIS
mdsetimage |
[-svx] [-b
bfdname] [-I
image_symbol] [-S
size_symbol] [-T
address] kernel
image |
DESCRIPTION
Themdsetimage 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.
