  18

  20
  21 - Relaxed check for Int13-Extension support.

  39
  40 - Minor tweak to UI code to allow description

  43
  44 Changes in v1.7.11 (12/05/2002) (brianp)
  45
  46 - Added memory map count to GetBiosMemoryMap() so that
  47   it doesn't just assume the size of the array.

  49   the BIOS returns.
  50
  51 Changes in v1.7.10 (11/24/2002) (brianp)
  52
  53 - Added assembler versions of memcmp() memcpy() memset()
  54 - Implemented Int386() so that real-mode interrupts can be called from C-code
  55 - Removed unnecessary call in DbgPrint() macro (freeldr.sys is ~16k smaller now)
  56 - 64-bit lba sector addressing for disk calls
  57 - Re-coded biosdisk.S as i386disk.c
  58 - Re-coded mem.S as i386mem.c
  59 - Re-coded rtlcode.S as i386rtl.c

  62 - Video fade in/out
  63 - VESA text modes supported now
  64 - Offscreen buffering to remove flicker

  66 - Prefixed all file system functions with 'Fs'
  67
  68 Changes in v1.7.9 (9/30/2002) (brianp)
  69
  70 - Fix for bug in BiosInt13ReadExtended() (biosdisk.S)
  71   by Christophe Bothamy & Mike Lerwill
  72
  73 Changes in v1.7.8 (9/7/2002) (ekohl)
  74
  75 - Added new 'bootcd' target.
  76 - Removed/disabled debugging code.
  77 - SetupLdr must not call BiosInt13ExtensionsSupported to check
  78   extended int13 capabilities because they are already used to
  79   boot a CD and some BIOSes return incorrect results when a CD-ROM
  80   drive is checked.
  81
  82 Changes in v1.7.7 (9/5/2002) (ekohl)
  83
  84 - fs/iso.c: Got iso-fs working again.
  85 - reactos/setupldr.c: Implemented very simple setup loader.
  86
  87 Changes in v1.7.6 (8/31/2002) (ekohl)
  88
  89 - bootsect/isoboot.asm: Reduced read transfer size to ensure that
  90   the read buffer for an int13/ah=42h (exended read) does not
  91   cross a segment boundary.
  92 - freeldr.c, bootmgr.c, setupldr.c, makefile: Renamed
  93   LoadBootManager() and ReactOSRunSetupLoader() to RunLoader().
  94   Either bootmgr.o or setupldr.o is used to build freeldr.sys or
  95   setupldr.sys
  96
  97 Changes in v1.7.5 (8/21/2002) (brianp)
  98
  99 - biosvid.S (BiosVideoDisableBlinkBit): Added code to
 100   disable the blink bit in the text mode character
 101   attribute byte so that the full range of
 102   background colors can be used.
 103
 104 Changes in v1.7.4 (8/20/2002) (brianp)
 105
 106 - Boot sector code now reports to freeldr.sys the partition
 107   that it was installed on. This is specified by a byte
 108   value in the boot sector code. By default the boot partition
 109   is set to zero which indicates the active (bootable)
 110   partition, unless the installer sets the value to non-zero.
 111   If FreeLoader is installed on a partition other than
 112   the active (bootable) partition then the installer must
 113   set this byte to that partition number. Otherwise
 114   FreeLoader will not be able to find freeldr.ini.
 115 - i386trap.S: Added debug macros BREAKPOINT(),
 116   INSTRUCTION_BREAKPOINTX(), MEMORY_READWRITE_BREAKPOINTX(), &
 117   MEMORY_WRITE_BREAKPOINTX().
 118 - partition.c (DiskGetPartitionEntry): Add the relative offset
 119   of the extended partition to the partitions start sector.
 120 - ext2.c (Ext2ReadBlockPointerList, Ext2CopyIndirectBlockPointers,
 121   Ext2CopyDoubleIndirectBlockPointers, Ext2CopyTripleIndirectBlockPointers):
 122   Rewrote the block pointer functions so they actually work.
 123 - ini_init.c (IniFileInitialize, IniOpenIniFile): Looks for freeldr.ini
 124   on both the active (bootable) partition and the partition
 125   passed in from the boot sector code.
 126 - meminit.c (MmInitializeMemoryManager, MmFixupSystemMemoryMap,
 127   MmGetEndAddressOfAnyMemory, MmGetAddressablePageCountIncludingHoles,
 128   MmInitPageLookupTable): Fixed bug that would cause FreeLoader to
 129   have an off-by-one error when accessing the last entry in the
 130   page lookup table on systems with 4GB of memory (or memory mapped
 131   at the end of the address space).
 132
 133 Changes in v1.7.2 (8/7/2002) (brianp)
 134
 135 - Fragment size must be equal to the block size

 145 - Fixed bug in UI code.
 146 - Added '%%' format specifier to printf()-like functions.
 147 - Added functions __udivdi3 & __umoddi3 so that 64-bit division is now supported.
 148 - Changed types BYTE, WORD, DWORD, LONG, ULONG to U8, U16, U32, S32, U32
 149   so that you know the size of the variable across different
 150   architectures with different sized words & dwords, etc.
 151 - Types CHAR, UCHAR, PCHAR, PUCHAR, WCHAR, PWCHAR have not been
 152   changed yet (I haven't decided exactly how I'm going to handle unicode)
 153
