Flash: 0xA0000000..0xA1FFFFFF (0x80000000..0x81FFFFFF: physically identical,
but cacheable)
RAM 2 MB
0xA8000000..0xA81FFFFF (0x88000000..0x881FFFFF: physically identical, but
cacheable)
0xA8000000..0xA80287FF: VRAM
0xA80D35D0 : start of main memory
0xA80E3000 : end of main memory
0xA80F0000..0xA815FFFF: system stack (512 kB).
0xA8160000..0xA81DFFFF: add-in RAM area. It is shared by add-in static RAM and
add-in stack. The add-in static RAM starts at 0x88160000 (virtualized to
0x08100000). The add-in stack starts at 0x881E0000 and grows downwards (towards
the static RAM).
When an add-in is loaded, the complete add-in RAM is virtualized in
8x64kB-chunks (0x88160000->0x08100000..0x881D0000->0x08170000), possibly
allowing much more static RAM as with the legacy systems. Of course, you have
to take care for the limits. Otherwise the system will do, crashing.
0xA81E0000..0xA81FFFFF: heap.
0xAB800000..0xABD0FFFF: MCS backup area
Link cable type: 0xFD8013E0, byte (1: 3pin; 0: USB).
Checksums:
According to cfxm (http://www.omnimaga.org/index.php?PHPSESSID=8673ef5ea2e48c005dc66e3ea7ba42e8&topic=5610.msg144179#msg144179)
BIOS checksum at 0xA001FFFC:
0xA0000000..0xA00002FF + 0xA0000340..0xA001FFBF
OS checksum at 0xA0B5FFF8:
0xA0020000..0xA0B5FEAF + 0xA0B5FEF0..0xA0B5FFF7
In case of an OS mod, the checksums have to be adjusted. Otherwise the OS
won't come up.
