Function:	Performs initialization for disk booting
Description:	This function initializes the Leo manager for disk booting and then calls mfsInit to initialize the MFS library.

	mfsInitDiskRom calls mfsRomInit internally so that only the ROM area can be accessed.
mfsInitDiskRam calls mfsRamInit internally so that only the RAM area can be accessed.
mfsInitDiskRomRam calls both mfsRomInit and mfsRamInit internally so that the ROM area and RAM area can be accessed.
