Like the Workstation 4, the CF Daughter card is positioned to make the CF
card available at the IO panel where it can serve as a 'personality' module in
Windows Embedded CE 6.0 configurations.
LED1 is the hard disk activity indicator and is located just to the left of the
mini-DIN pole customer display connector.
The CF card is an intelligent solid state storage device containing a micro
controller and firmware positioned in front of a block of flash memory. The
firmware responds to file IO requests from the operating system file driver and
maps file data to/from the flash memory array.
