In what operation is the following info saved (OS restore, or GEM downloading) to the color chip: a) Display type b) SDRAM c) FLASH

The displaytype is loaded in a file called lcdConfig.bin, generated from the .tft file used in the LCD config menu.

The SDRAM settings exist in the folder:
XP: C:\Documents and Settings\All Users\Application Data\AmuletTech\Global\Configuration\SDRAM
VISTA/7: C:\Program Data\AmuletTech\Global\Configuration\SDRAM
These get compiled to another binary (sdramConfig.bin) and programmed with the OS

The Flash setting is not programmed. This is probably the most important piece of information, because different flash sizes have different page sizes. So a change of the flash size forces a recompile of the OS and project because it has to re-layout the flash utilization. The amulet chip will output a character in program mode that notifies the compiler of the flash size. This is the 'f' that we were looking for before, which means the flash is 32Mbit. The 'Z' means the chip cannot communicate with the flash. If this character does not match the setting in the compiler, it will not continue to program.
