# bootblok.s is the source of the MINIX boot block.  The bootblock is the
# first 512 bytes on the image file and on the boot diskette.  When bootblok.s
# is assembled, it generates a short binary file (less than 400 bytes) that
# must be stripped of its header and copied to the file bootblok.  The dd
# command below does this.  If everything has been done right, the bootblok
# file should begin with the following 8 words, in hex:
# c0b8 8e07 33d8 b8f6 2fe0 c08e ff33 00b9
# The exact procedure for going from bootblok.s to the binary file stripped of
# its header is somewhat operating system dependent.  Some assemblers make
# an object (.s) file; others make an a.sut file directly. If your boot 
# diskette does not start out by printing 'Booting MINIX 1.0' the problem is
# probably that you have not made a good boot block.

# 'make image'  combines the bootblock, kernel, memory manager, file 
# system, init and fsck into a single file, called image.  Each of these pieces
# appears in the image file just as the original does on the disk, except that
# the header at the front is removed, and each piece is padded out to an
# integral multiple of 16 bytes.  Build also prints a message telling how big
# the various pieces (except fsck) are.
