	maintenance programs such as the System Menu, etc., are stored in this
	drive.

[Read and Write]	Application programs are stored on this drive. The drive size (storage
	capacity) differs depending on the model.
Drive E:	Drive for Windows files
[Read Only]	A ROM that stores Windows files is assigned to the drive E.
	This is a reserved drive on IT-2000D models. In this case note that if this
	drive is accessed , an INT24h error will occur.

	For information about the mechanism of booting a card refer to
	Chapter 4.3 “Card Boot”.

[Read and Write]	This drive is required if the application program accesses the PC card.
	This drive is prepared for use by loading the PC card driver via
	CONFIG.SYS.
