- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
-                          675 Mass Ave, Cambridge, MA 02139, USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	Appendix: How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) 19yy  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) 19yy name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Library General
-Public License instead of this License.

-
-; This is a FAT12/16 file system boot sector
-; that searches the entire root directory
-; for the file freeldr.sys and loads it into
-; memory.
-;
-; The stack is set to 0000:7BF2 so that the first
-; WORD pushed will be placed at 0000:7BF0
-;
-; The DWORD at 0000:7BFC or BP-04h is the logical
-; sector number of the start of the data area.
-;
-; The DWORD at 0000:7BF8 or BP-08h is the total
-; sector count of the boot drive as reported by
-; the computers bios.
-;
-; The WORD at 0000:7BF6 or BP-0ah is the offset
-; of the ReadSectors function in the boot sector.
-;
-; The WORD at 0000:7BF4 or BP-0ch is the offset
-; of the ReadCluster function in the boot sector.
-;
-; The WORD at 0000:7BF2 or BP-0eh is the offset
-; of the PutChars function in the boot sector.
-;
-; When it locates freeldr.sys on the disk it will
-; load the first sector of the file to 0000:8000
-; With the help of this sector we should be able
-; to load the entire file off the disk, no matter
-; how fragmented it is.
-;
-; We load the entire FAT table into memory at
-; 7000:0000. This improves the speed of floppy disk
-; boots dramatically.

-		; We are now ready to load our second sector of boot code
-		; But first, a bit of undocumented information about how
-		; Win2k stores it's second sector of boot code.
-		;
-		; The FAT32 filesystem was designed so that you can store
-		; multiple sectors of boot code. The boot sector of a FAT32
-		; volume is actually three sectors long. Microsoft extended
-		; the BPB so much that you can't fit enough code in the
-		; boot sector to make it work. So they extended it. Sector 0
-		; is the traditional boot sector, sector 1 is the FSInfo sector,
-		; and sector 2 is used to store extra boot code to make up
-		; for the lost space the BPB takes.
-		;
-		; Now this creates an interesting problem. Suppose for example
-		; that the user has Win98 and Win2k installed. The Win2k
-		; boot sector is stored at sector 0 and the Win98 boot sector is
-		; stored as BOOTSECT.DOS on the file system. Now if Win2k were
-		; to store it's second sector of boot code in sector 2 like
-		; the fat spec says to do then when you try to dual boot back
-		; to Win98 the Win98 boot sector will load Win2k's second
-		; sector of boot code. Understand? ;-)
-		;
-		; To get around this problem Win2k stores it's second sector
-		; of boot code elsewhere. This sector is always stored at sector 13
-		; on the file system. Now don't ask me what happens when you don't
-		; have enough reserved sectors to store it, but I've never seen a
-		; FAT32 volume that didn't have at least 32 reserved sectors.

-// Members
-//  ReadIntervalTimeout 
-//   Specifies the maximum time, in milliseconds, allowed to elapse between the arrival of two characters on the communications line. During a ReadFile operation, the time period begins when the first character is received. If the interval between the arrival of any two characters exceeds this amount, the ReadFile operation is completed and any buffered data is returned. A value of zero indicates that interval time-outs are not used. 
-//   A value of MAXDWORD, combined with zero values for both the ReadTotalTimeoutConstant and ReadTotalTimeoutMultiplier members, specifies that the read operation is to return immediately with the characters that have already been received, even if no characters have been received. 
-// 
-//  ReadTotalTimeoutMultiplier 
-//   Specifies the multiplier, in milliseconds, used to calculate the total time-out period for read operations. For each read operation, this value is multiplied by the requested number of bytes to be read. 
-//  ReadTotalTimeoutConstant 
-//   Specifies the constant, in milliseconds, used to calculate the total time-out period for read operations. For each read operation, this value is added to the product of the ReadTotalTimeoutMultiplier member and the requested number of bytes. 
-//   A value of zero for both the ReadTotalTimeoutMultiplier and ReadTotalTimeoutConstant members indicates that total time-outs are not used for read operations. 
-// 
-//  WriteTotalTimeoutMultiplier 
-//   Specifies the multiplier, in milliseconds, used to calculate the total time-out period for write operations. For each write operation, this value is multiplied by the number of bytes to be written. 
-//  WriteTotalTimeoutConstant 
-//   Specifies the constant, in milliseconds, used to calculate the total time-out period for write operations. For each write operation, this value is added to the product of the WriteTotalTimeoutMultiplier member and the number of bytes to be written. 
-//   A value of zero for both the WriteTotalTimeoutMultiplier and WriteTotalTimeoutConstant members indicates that total time-outs are not used for write operations. 
-// 
-// Remarks
-//  If an application sets ReadIntervalTimeout and ReadTotalTimeoutMultiplier to MAXDWORD and sets ReadTotalTimeoutConstant to a value greater than zero and less than MAXDWORD, one of the following occurs when the ReadFile function is called: 
-// 
-//   If there are any characters in the input buffer, ReadFile returns immediately with the characters in the buffer. 
-//   If there are no characters in the input buffer, ReadFile waits until a character arrives and then returns immediately. 
-//   If no character arrives within the time specified by ReadTotalTimeoutConstant, ReadFile times out.

-
-- Added new 'bootcd' target.
-- Removed/disabled debugging code.

-
-Changes in v1.7.7 (9/5/2002) (ekohl)
-
-- fs/iso.c: Got iso-fs working again.
-- reactos/setupldr.c: Implemented very simple setup loader.
-
-Changes in v1.7.6 (8/31/2002) (ekohl)
-
-- bootsect/isoboot.asm: Reduced read transfer size to ensure that
-  the read buffer for an int13/ah=42h (exended read) does not
-  cross a segment boundary.
-- freeldr.c, bootmgr.c, setupldr.c, makefile: Renamed
-  LoadBootManager() and ReactOSRunSetupLoader() to RunLoader().

-
-Changes in v1.7.4 (8/20/2002) (brianp)
-
-- Boot sector code now reports to freeldr.sys the partition
-  that it was installed on. This is specified by a byte
-  value in the boot sector code. By default the boot partition
-  is set to zero which indicates the active (bootable)
-  partition, unless the installer sets the value to non-zero.
-  If FreeLoader is installed on a partition other than
-  the active (bootable) partition then the installer must
-  set this byte to that partition number. Otherwise
-  FreeLoader will not be able to find freeldr.ini.
-- i386trap.S: Added debug macros BREAKPOINT(),
-  INSTRUCTION_BREAKPOINTX(), MEMORY_READWRITE_BREAKPOINTX(), &
-  MEMORY_WRITE_BREAKPOINTX().
-- partition.c (DiskGetPartitionEntry): Add the relative offset
-  of the extended partition to the partitions start sector.
-- ext2.c (Ext2ReadBlockPointerList, Ext2CopyIndirectBlockPointers,
-  Ext2CopyDoubleIndirectBlockPointers, Ext2CopyTripleIndirectBlockPointers):
-  Rewrote the block pointer functions so they actually work.
-- ini_init.c (IniFileInitialize, IniOpenIniFile): Looks for freeldr.ini
-  on both the active (bootable) partition and the partition
-  passed in from the boot sector code.
-- meminit.c (MmInitializeMemoryManager, MmFixupSystemMemoryMap,
-  MmGetEndAddressOfAnyMemory, MmGetAddressablePageCountIncludingHoles,
-  MmInitPageLookupTable): Fixed bug that would cause FreeLoader to
-  have an off-by-one error when accessing the last entry in the
-  page lookup table on systems with 4GB of memory (or memory mapped
-  at the end of the address space).
-
-Changes in v1.7.2 (8/7/2002) (brianp)
-
-- Fragment size must be equal to the block size
-
-Changes in v1.7.1 (8/7/2002) (brianp)
-
-- Symbolic links on EXT2/3 are now supported
-
-Changes in v1.7 (8/6/2002) (brianp)
-
-- EXT2/EXT3 file system support.

-- Fixed bug in UI code.
-- Added '%%' format specifier to printf()-like functions.
-- Added functions __udivdi3 & __umoddi3 so that 64-bit division is now supported.
-- Changed types BYTE, WORD, DWORD, LONG, ULONG to U8, U16, U32, S32, U32
-  so that you know the size of the variable across different
-  architectures with different sized words & dwords, etc.
-- Types CHAR, UCHAR, PCHAR, PUCHAR, WCHAR, PWCHAR have not been
-  changed yet (I haven't decided exactly how I'm going to handle unicode)

-- Places all output into one single directory
-- Added automagically generated dependencies
-
-Changes in v1.2 (4/30/2002)
-
-- All Linux kernels are supported (zImage & bzImage, loaded high & low)
-- Initrd support
-- FreeLoader now compiles under Mingw32 instead of just DJGPP, but
-  the Mingw32 linker seems to output a corrupt binary.
-
-Changes in v1.01 (4/28/2002)
-
-- Fixed FAT short file name buffer overflow that was causing
-  some long filenames not to work correctly.
-
-Changes in v1.0 (4/24/2002)
-
-- FreeLoader version 1.0!
-- Supports booting ReactOS
-- Supports booting Linux bzImage kernels
-- No initrd support (yet)
-- No zImage support (yet)
-- No ext2 file system support (yet)
-- Supports FAT & ISO-9660 file systems
-- Forward slashes '/' as well as backslashes '\' can be used
-  for path names in FAT & ISO-9600
-- Fixed bug in LBA code where it was only reading one sector
-  even if you asked for more
-- Fixed bug in FAT code, was also present in ISO-9660 code where
-  it wasn't incrementing the buffer address correctly

-// more memory than currently installed or are not supported by the
-// attached monitor. Check any mode you intend to use through AX=4F01h first..
-// The 1.1 VESA document specifies 242 reserved bytes at the end, so the
-// buffer should be 262 bytes to ensure that it is not overrun; for v2.0,
-// the buffer should be 512 bytes. The S3 specific video modes will most
-// likely follow the FFFFh terminator at the end of the standard modes.
-// A search must then be made to find them, FFFFh will also terminate this
-// second list. In some cases, only a "stub" VBE may be present, supporting
-// only AX=4F00h; this case may be assumed if the list of supported video modes
-// is empty (consisting of a single word of FFFFh)
