MagicianRomLayout

the magician has a 64M rom, containing both os, and extended rom.

layout:

80000000-80040000	0040000	BootLoader
80040000-82400000	23C0000	osROM
82400000-82c00000	0800000	backup area ( contacts, calendar, etc )
82c00000-83f00000	1300000	extended rom
83f00000-83f80000	0080000	unused
83f80000-83fc0000	0040000	bootsplash image
83fc0000-84000000	0040000	device version + type information

with the big-storage patch, the layout looks like this:

80000000-80040000	0040000	BootLoader
80040000-82400000	23C0000	osROM
82400000-83f80000	1B80000	Storage folder
83f80000-83fc0000	0040000	bootsplash image
83fc0000-84000000	0040000	device version + type information

note that the os rom is 36M, so to make a dump of the rom using pmemdump, you'd have to type:

pmemdump 0x80000000 0x2400000 romdump.raw

or when using the bootloader:

d2s 80000000 02400000

And if you do not want to touch the bootLoader ROM piece.

pmemdump 0x80400000 0x23C0000 romdump.raw

or...

d2s 80040000 023C0000

You can also backup the radio rom, atleast using the bootLoader (the radio is outside the "normal" flash space):

d2s 60000000 00300000

NOTE: Although the radio_.nbf contains 0x400000 bytes of data, the SD dump has to be 0x300000. Trying to install a 0x400000 bytes dump causes an 'Error Downloading' at 68%. Happily, The message is harmless, and the radio is correctly flashed.

Note: d2s with no parameter will backup your whole ROM including OS and Extended_Rom but without the Bootloader (d2s 80040000 03FC0000)
