1.2 Windows CE Startup Procedure

Windows CE can be loaded by two methods, first is by Compact Flash card, and

second is by system flash chip. Compact Flash card is high boot priority than system

flash chip. In BOOTLOADER criteria, it will first read the Windows CE image in

Compact Flash card. If Compact Flash card is unavailable or no Windows CE image

inside, BOOTLOADER will load the Windows CE image from system flash chip.

BOOTLOADER copy Windows CE image to DRAM and launch WinCE from

DRAM, whenever loaded by Compact Flash card or system flash chip.

Therefore, there are some advantages,

1, Easy Windows CE image installation: Customer can copy Windows CE image they

want to Compact Flash card, and then load this image by BOOTLOADER.

2, Flexible Hardware design : Flash on board design is unnecessary. The Windows CE

can be loaded by Compact Flash card.
