Full-Kernel Mode (Windows CE 5.0)
You can run all of the OS threads in either kernel mode or user mode. Although running threads in kernel mode leaves the entire system vulnerable, it also enables increased performance. This is because Windows CE bypasses security functionality that can prevent a thread from entering kernel mode. This may be acceptable in a closed environment, but in an open environment, this can have dramatic effects on security that you must consider. The default behavior is for full-kernel mode. To disable full-kernel mode, ROMFLAGS in the Config.bib file must have its second bit set. Depending on what other flags are set, the value of ROMFLAGS might vary.
