Figure 4.3 Upgrade utility
Note: The difference between NK.NB0 (Compressed) and NK.NB0 (Normal, XIP) :
The option “NK.NB0 (Normal, XIP)” means that the nk.nb0 will be upgraded directly
to the flash ROM, and “NK.NB0 (Compressed)” means that we compress nk.nb0 first,
and then write the compressed data to the flash ROM. :
(1) Boot time : compressed image take more time in system bootup.
(2) IPSM size : compressed OS image would result in larger IPSM size.
Step4. Press ‘Apply’ button on the dialog. Then the items you select will be upgraded
to the flash ROM. See Figure 4-4.

time boot, it will take about 1 minute to format the IPSM.
4.4 Utilities
There are several useful utilities added in the standard Windows
®
CE.NET OS:
4.4.1 Regflash
The utility "Regflash" is a convenient tool to save, overwrite or delete registry data, as
well as erase the content of IPSM folder. From the Windows
®
CE.NET status bar, tap

box and press "OK". There are four selections here:
Save to Flash, Delete from Flash, Save to CF Disk, Erase IPSM.

option was used to save the registry setting to on board flash ROM. In contrast,
"Delete from Flash" option was intended to erase the on board registry data. "Save to
CF Disk" option would save the registry data to CompactFlash card as a file
"wince.reg". "Erase IPSM" option erase the IPSM region of the on board flash.
