273b6dd69f Fixed the EXT2/3 boot sector code so that it only uses the boot drive in the boot sector if it exists (i.e. not 0xff)
Otherwise it uses the boot drive passed in the DL register.
Updated the EXT2/3 installer to reflect the changes in the boot sector code for EXT2/3.

425bbb1543 Changes in v1.7.10 (11/24/2002) (brianp)
- Added assembler versions of memcmp() memcpy() memset()
- Implemented Int386() so that real-mode interrupts can be called from C-code
- Removed unnecessary call in DbgPrint() macro (freeldr.sys is ~16k smaller now)
- 64-bit lba sector addressing for disk calls
- Re-coded biosdisk.S as i386disk.c
- Re-coded mem.S as i386mem.c
- Re-coded rtlcode.S as i386rtl.c
- Cleaned up i386trap.S so that it only saves the registers once.
- Re-coded biosvid.S as i386vid.c
- Video fade in/out
- VESA text modes supported now
- Offscreen buffering to remove flicker
- Standardized format of boot sector so that BootPartition is stored right before 0xaa55
- Prefixed all file system functions with 'Fs'

fb29fa8a10 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.

bd3e14d1f7 Added a workaround for broken BIOSes.

0f2ad47bfb Fix for disk error while Loading FreeLoader... discovered by Dave Albert

367cfa7085 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).
