Changes in v1.7.9 (9/30/2002) (brianp)

- Fix for bug in BiosInt13ReadExtended() (biosdisk.S)
  by Christophe Bothamy & Mike Lerwill

Changes in v1.7.8 (9/7/2002) (ekohl)

- Added new 'bootcd' target.
- Removed/disabled debugging code.
- SetupLdr must not call BiosInt13ExtensionsSupported to check
  extended int13 capabilities because they are already used to
  boot a CD and some BIOSes return incorrect results when a CD-ROM
  drive is checked.

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().
  Either bootmgr.o or setupldr.o is used to build freeldr.sys or
  setupldr.sys  

Changes in v1.7.5 (8/21/2002) (brianp)

- biosvid.S (BiosVideoDisableBlinkBit): Added code to
  disable the blink bit in the text mode character
  attribute byte so that the full range of
  background colors can be used.

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.
- Does not yet support symbolic links or booting from an EXT2/3 partition.
- 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)

Changes in v1.3 (6/5/2002)

- Added protected mode exception handling in case FreeLoader crashes
- Reworked memory manager to use all of extended memory

  the Mingw32 linker seems to output a corrupt binary.

Changes in v1.01 (4/28/2002)

  some long filenames not to work correctly.

  it wasn't incrementing the buffer address correctly
