- 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'
svn path=/trunk/; revision=3782
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.

- 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.
svn path=/trunk/; revision=3374
- 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).
svn path=/trunk/; revision=3372
- 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)
svn path=/trunk/; revision=2651
New .ini file format (sort of) - changed some parameter names, etc.
More efficient .ini file parsing code
More efficient use of memory, smaller image file
Total rewrite of file system code (the old stuff sucked)
VFAT Long File Names now supported!
ReactOS is the only boot type supported currently, disabled all others (temporarily)
