+
+[me:]
+> Currently i lack of blob and prescriptions.
+
+The blobs are available in the Syslinux build tree under the names:
+
+mbr/isohdp[fp]x*.bin
+
+The default probably should be mbr/isohdppx.bin, but it's ultimately up
+to the user.
+
+User definable parameters:
+
+-> MBR ID		(default random 32-bit number,
+			 or preserved from previous instance)
+-> Sector count		(default 32, range 1-63)
+-> Head count		(default 64, range 1-256)
+-> Partition offset	(default 0, range 0-64)
+-> Partition number	(default 1, range 1-4)
+-> Filesystem type	(default 0x17, range 1-255)
+
+Note: the filesystem type is largely arbitrary, in theory it can be any
+value other than 0x00, 0x05, 0x0f, 0x85, 0xee, or 0xef.  0x17 ("Windows
+IFS Hidden") seems safeish, some people believe 0x83 (Linux) is better.
+
+Here is the prescriptions for how to install it:
+
+All numbers are littleendian.  "word" means 16 bits, "dword" means 32
+bits, "qword" means 64 bits.
+
+Common subroutine LBA_to_CHS():
+	s = (lba % sector_count) + 1
+	t = (lba / sector_count)
+	h = (t % head_count)
+	c = (t / head_count)
+
+	if (c >= 1024):
+		c = 1023
+		h = head_count
+		s = sector_count
+
+	s = s | ((c & 0x300) >> 2)
+	c = c & 0xff
+
+	write byte h
+	write byte s
+	write byte c
+
+Main:
+	Pad image_size to a multiple of sector_count*head_count
+	Use the input file unmodified for bytes 0..431
+	write qword boot_lba		# Offset 432
+	write dword mbr_id		# Offset 440
+	write word 0			# Offset 444
+
+	# Offset 446
+	For each partition entry 1..4:
+		if this_partition != partition_number:

+		else:
+			write byte 0x80
+			write LBA_to_CHS(partition_offset)
+			write byte filesystem_type
+			write LBA_to_CHS(image_size-1)
+			write dword partition_offset
+			write dword image_size
