Memory Map...  Assumes 32 MB

Physical Address

Open Firmware Version     1x, 2x                        3x
00000000 - 00003FFF  :             Exception Vectors
00004000 - 002FFFFF  :                Free Memory
00300000 - 004FFFFF  :   OF Image         /            Free Memory
00500000 - 01DFFFFF  :                Free Memory
01E00000 - 01FFFFFF  :   Free Memory      /            OF Image


Logical Address

00000000 - 00003FFF  : Exception Vectors
00004000 - 013FFFFF  : Kernal Image, Boot Struct and Drivers
01400000 - 01BFFFFF  : File Load Area
01C00000 - 01CFFFFF  : Secondary Loader Image
01D00000 - 01DFFFFF  : Malloc Area
01E00000 - 01FFFFFF  : Unused

To provide a consistant Logical Memory Usage between OF 1,2 and OF 3
the Logical Addresses 0x00300000 - 0x004FFFFF will be mapped to
Physical Address 0x01E00000 - 0x01FFFFFF and will be copied back
just before the kernel is loaded.
