- 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).

- 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)
(isn't this an awesome commit? ;-) Just look at that list of files)
svn path=/trunk/; revision=3318
- Implemented MmAllocateMemoryAtAddress()
- Fixed Linux boot code to go through the memory manager to allocate memory at 1MB
svn path=/trunk/; revision=3027
- Added protected mode exception handling in case FreeLoader crashes
- Reworked memory manager to use all of extended memory
- Reworked UI code, now supports multiple text-mode resolutions
svn path=/trunk/; revision=3010
- Makefile updates
- Optimized the Makefile
- Removed recursive make functionality (builds much faster now)
- Places all output into one single directory
- Added automagically generated dependencies
svn path=/trunk/; revision=2904
- 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.
svn path=/trunk/; revision=2899
Supports booting Linux bzImage kernels
No initrd support (yet)
No zImage support (yet)
No ext2 file system support (yet)
Forward slashes '/' as well as backslashes '\' can be used for path names in FAT & ISO-9660
Fixed bug in LBA code where is was only reading one sector even if you asked for more
Fixed bug in FAT code, was also present in ISO-9660 code
svn path=/trunk/; revision=2867
Leading whitespace in a line is now ignored
Changed .ini file comment character from '#' to ';' to be compatible with MS
There is still a mysterious memory allocation failed bug however!?
svn path=/trunk/; revision=2741
Fixed a bug in the root directory size calculations for FAT12 & FAT16 (I must have been smoking something when I wrote that).
Started work on new .ini file code, the old stuff is just way too slow.
svn path=/trunk/; revision=2676
Extended partitions are supported (untested)
If you call OpenDrive() with Partition == 0 you get the active (or bootable) partition
Partitions 1 - 4 are the primary partitions
Partitions 5 - n are the extended partitions
Also added disk parameter detection code (always assumes 512 byte sector size, I don't like that but I don't see any other way)
