Migrating from a 700 Monochrome Computer
As you migrate from a 700 Monochrome Computer to a 700 Color Com-
puter, you need to consider the following: When converting a 700 Mono-
chrome Computer application to run on the 700 Color Computer, most
APIs should work without changes. Below are a few exceptions:
S The 700 Monochrome Computer uses the “\Storage Card” folder for
nonvolatile storage. You may need to change the application to store
data onto the “SDMMC Disk” folder instead of the “\Storage Card”
folder if a Secure Digital storage card is present in the system.
S If the application uses the RegFlushKey() API, it must first ver if y that
the proper media is available in the system and call the special API men-
tioned in Step 7 on the previous page.
S Iftheapplicationisusingthe700Colorswitchabledock,usethe
IOCTL_DOCK_SWITCH value from the
IOCTL_HAL_ITC_WRITE_SYSPARM function to set the proper
port on the dock before communications. See more information about
this KernelIOControl function in Chapter 7, “Programming.”
S Some WAN radio options have changed. Review the WAN radio infor-
mation in Chapter 4, “Network Support,“to determine if any changes are
required in your application.
S Arrow and tab keys are reversed from the 700 Monochrome Computer.
Keyboard re mapping is available on the 700 Color Computer should
you need to map these keys like that of the 700 Monochrome Comput-
er (see page 127).
S Special Resource Kits are not needed to compile applications f or the
Xscale processor. Targeting the SA1110 processor creates applications

Installing Cabinet Files
CAB f iles (short form of “cabinet” files) are compressed folders as defined by
Microsoft. A “cabinet” file is a single file, usually suf fixed with .CAB, that
stores compressed files in a file library. A compressed file can be spread
over several cabinet files. During installation, the setup application decom-
presses the files stored in a cabinet and copies them to the user’s system.
For the 700 Series Computer, CAB f iles register DLLs, create shortcuts,
modify registry entries, and run custom setup programs. Tap a CAB file to
extract that file or place the CAB file on one of the approved storage de-
vices in the “\CabFiles” folder, then perform a warm-boot on the 700 Se-
ries Computer. There are two methods available to extract a CAB file:
S Tap a CAB file to extract it. With this method, the CAB file is automat-
ically deleted when the extraction process is successful, unless the CAB
file is set with the read-only attribute.
S Use AUTOCAB to extract all files when a cold-boot is performed on
the 700 Series Computer. See the Software Tools User’s Manual for in-
formation.
