-                        Overview of libburnia-project.org
-
-libburnia-project.org is an open-source software project for reading, mastering
-and writing optical discs.
-For now this means only CD media and all single layer DVD media except DVD+R.
-
-The project comprises of several more or less interdependent parts which
-together strive to be a usable foundation for application development.
-These are libraries, language bindings, and middleware binaries which emulate
-classical (and valuable) Linux tools.
-
-Our scope is currently Linux 2.4 and 2.6 only. For ports to other systems
-we would need : login on a development machine resp. a live OS on CD or DVD,
-advise from a system person about the equivalent of Linux sg or FreeBSD CAM,
-volunteers for testing of realistic use cases.
-
-We have a workable code base for burning CD and most single layer DVD.
-The burn API is quite comprehensively documented and can be used to build a
-presentable application.
-We have a functional binary which emulates parts of cdrecord in order to
-prove that usability, and in order to allow you to explore libburnia's scope
-by help of existing cdrecord frontends.
-
-The project components (list subject to growth, hopefully):
-
-- libburn  is the library by which preformatted data get onto optical media.
-           It uses either /dev/sgN (e.g. on kernel 2.4 with ide-scsi) or
-           /dev/hdX (e.g. on kernel 2.6).
-           libburn is the foundation of our cdrecord emulation. Its code is
-           independent of cdrecord. Its DVD capabilities are learned from
-           studying the code of dvd+rw-tools and MMC-5 specs. No code but only
-           the pure SCSI knowledge has been taken from dvd+rw-tools, though.
-
-- libisofs is the library to pack up hard disk files and directories into a
-           ISO 9660 disk image. This may then be brought to media via libburn.
-           libisofs is to be the foundation of our upcoming mkisofs emulation.
-
-- cdrskin  is a limited cdrecord compatibility wrapper for libburn.
-           Cdrecord is a powerful GPL'ed burn program included in Joerg
-           Schilling's cdrtools. cdrskin strives to be a second source for
-           the services traditionally provided by cdrecord. Additionally it
-           provides libburn's DVD capabilities, where only -sao is compatible
-           with cdrecord.
-           cdrskin does not contain any bytes copied from cdrecord's sources.
-           Many bytes have been copied from the message output of cdrecord
-           runs, though.
-           See cdrskin/README and man cdrskin/cdrskin.1 for more.
-
-- test     is a collection of application gestures and examples given by the
-           authors of the library features. The main API example for libburn
-           is test/libburner.c .
-           Explore these examples if you look for inspiration.
-
-We plan to be a responsive upstream. Bear with us. We are still practicing.
-
-
-------------------------------------------------------------------------------
-Project history as far as known to me:
-
-- Founded in 2002 as it seems. See mailing list archives
-     http://lists.freedesktop.org/archives/libburn/
-  The site of this founder team is reachable and offers download of a
-  (somewhat outdated) tarball and from CVS :
-     http://icculus.org/burn/
-  Copyright holders and most probably founders:
-  Derek Foreman and Ben Jansens.
-
-- I came to using libburn in 2005. Founded the cdrskin project and submitted
-  necessary patches which were accepted or implemented better. Except one
-  remaining patch which prevented cdrskin from using vanilla libburn from CVS.
-  The cdrskin project site is reachable and offers download of the heavily
-  patched (elsewise outdated) tarball under the name  cdrskin-0.1.2  :
-     http://scdbackup.sourceforge.net/cdrskin_eng.html
-  It has meanwhile moved to use vanilla libburn.pykix.org , though.
-  Version 0.1.4 constitutes the first release of this kind.
-
-- In July 2006 our team mate Mario Danic announced a revival of libburn
-  which by about nearly everybody else was perceived as unfriendly fork.
-  Derek Foreman four days later posted a message which expressed his
-  discontent.
-  The situation first caused me to publically regret it and then - after i
-  got the opportunity to move in with cdrskin - gave me true reason to
-  personally apologize to Derek Foreman, Ben Jansens and the contibutors at 
-  icculus.org/burn. Posted to both projects:
-    http://lists.freedesktop.org/archives/libburn/2006-August/000446.html
-    http://mailman-mail1.webfaction.com/pipermail/libburn-hackers/2006-August/000024.html
-
-- Mid August 2006 project cdrskin established a branch office in 
-  libburn.pykix.org so that all maintainers of our tools have one single place
-  to get the current (at least slightely) usable coordinated versions of
-  everything.
-  Project cdrskin will live forth independendly for a while but it is committed
-  to stay in sync with libburn.pykix.org (or some successor, if ever).
-  cdrskin is also committed to support  icculus.org/burn  if the pending fork
-  is made reality by content changes in that project. It will cease to maintain
-  a patched version of  icculus.org/burn  though. Precondition for a new
-  release of cdrskin on base of  icculus.org/burn  would be the pending
-  "whitelist patch" therefore.
-  I would rather prefer if both projects find consense and merge, or at least
-  cooperate. I have not given up hope totally, yet.
-  I, personally, will honor any approach.
-
-- 2nd September 2006 the decision is made to strive for a consolidation of
-  copyright and a commitment to GPL in a reasonable and open minded way.
-  This is to avoid long term problems with code of unknown origin and
-  with finding consense among the not so clearly defined group of copyright
-  claimers and -holders.
-  libisofs is already claimed sole copyright Mario Danic.
-  cdrskin and libburner are already claimed sole copyright Thomas Schmitt.
-  Rewrites of other components will follow and concluded by claiming full
-  copyright within the group of libburn.pykix.org-copyright holders.
-
-- 16th September 2006 feature freeze for release of libburn-0.2.2 .
-
-- 20th September 2006 release of libburn-0.2.2 .
-
-- 26th October 2006 feature freeze for cdrskin-0.2.4 based on libburn-0.2.3 .
-  This version of cdrskin is much more cdrecord compatible in repect
-  to drive addressing and audio features.
-
-- 30th October 2006 release of cdrskin-0.2.4 .
-
-- 13th November 2006 splitting releases of libburn+cdrskin from libisofs.
-
-- 24th November 2006 release of libburn-0.2.6 and cdrskin-0.2.6 . cdrskin has
-  become suitable for unaware frontends as long as they perform only the core 
-  of cdrecord use cases (including open-ended input streams, audio, and
-  multi-session).
-
-- 28th November 2006 the umbrella project which encloses both, libisofs and
-  libburn, is now called libburnia. For the origin of this name, see 
-  http://en.wikipedia.org/wiki/Liburnians .
-
-- 16th January 2007 release of libburn-0.3.0 and cdrskin-0.3.0 . Now the scope
-  is widened to a first class of DVD media: overwriteable single layer types
-  DVD-RAM, DVD+RW, DVD-RW. This is not a cdrecord emulation but rather inspired
-  by dvd+rw-tools' "poor man" writing facility for this class of media.
-  Taking a bow towards Andy Polyakov.
-
-- 11th February 2007 version 0.3.2 covers sequential DVD-RW and DVD-R with
-  multi-session and with DAO.
-
-- 12th March 2007 version 0.3.4 supports DVD+R and thus covers all single layer
-  DVD media. Code for double layer DVD+/-R is implemented but awaits a tester
-  yet.
-
-- 23th April 2007 version 0.3.6 follows the unanimous opinion of Linux kernel
-  people that one should not use /dev/sg on kernel 2.6.
-
-- 31st July 2007 version 0.3.8 marks the first anniversary of libburn revival.
-  We look back on improved stability, a substantially extended list of media
-  and write modes, and better protection against typical user mishaps.
-
-- 24th October 2007 version 0.4.0 is the foundation of new library libisoburn
-  and an upcomming integrated application for manipulating and writing
-  ISO 9660 + Rock Ridge images. cdrskin-0.4.0 got capabilities like growisofs
-  by these enhancements: growing of overwriteable media and disk files.
-  Taking again a bow towards Andy Polyakov.
-
-- 26th Januar 2008 version 0.4.2 rectifies the version numbering so that we
-  reliably release libburn.so.4 as should have been done since libburn-0.3.2.
-  cdrskin now is by default linked dynamically and does a runtime check
-  to ensure not to be started with a libburn which is older than itself.

+The session checksum tag does not occupy its whole block. So there is room to
+store a scdbackup stream checksum tag, which is an ancestor format of the tags
+described here. This feature allows scdbackup to omit its own checksum filter
+if using xorriso as ISO 9660 formatter program.
+Such a tag makes only sense if the session begins at LBA 0.

+See scdbackup-*/README, appendix VERIFY for a specification.

+
+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.

+
+	if (c >= 1024):
+		c = 1023
+		h = head_count
+		s = sector_count
