FreeLoader notes
|
|
|
|
To build FreeLoader you will need DJGPP because Mingw32 doesn't support 16-bit code
|
|
FreeLoader does not currently work with extended partitions.
|
|
Linux booting support needs to be added.
|
|
ext2 filesystem support needs to be added.
|
|
|
|
Current memory layout:
|
|
|
|
0000:0000 - 0000:0FFF: Interrupt vector table & BIOS data
|
|
0000:1000 - 0000:6FFF: Real mode stack area
|
|
0000:7000 - xxxx:xxxx: FreeLoader program & data area
|
|
xxxx:xxxx - 6000:0000: Protected mode stack area & heap
|
|
6000:0000 - 6000:C000: Filesystem data buffer
|
|
6000:C000 - 7000:0000: FREELDR.INI loaded here
|
|
7000:0000 - 7000:FFFF: scratch area for any function's use (ie sector buffer for biosdisk()) - can be overwritten by any function
|
|
8000:0000 - 9000:FFFF: fat table entry buffer
|
|
A000:0000 - FFFF:FFFF: reserved
|
