The CPU is an Intel Xscale PXA255 running at 400 MHz. 

A CF Card FLASH is used for ROM, Flash for Windows CE and Flash memory for bundled 
applications. The Flash is configured as the primary boot device and contains the Windows CE 
image, boot loader, OAL, applications, utilities and device drivers.  

Any flash remaining beyond the Windows CE image is formatted for use as a persistent memory 
drive (which appears in My Computer as the folder “System”).  

The computer has one Type II CF+ slot. The computer supports and auto detects up to 256MB of 
Type I compact flash memory.

battery is not user serviceable and should last five years with normal use before it requires 
replacement.
