- Added memory map count to GetBiosMemoryMap() so that
it doesn't just assume the size of the array.
- Fix so that we use the continuation value that
the BIOS returns.
svn path=/trunk/; revision=3823
- 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'

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.
