The above assumes that the OS will actually make the physical addresses of interest to you available in your applications virtual address space. Note that some PalmOS devices seem to run apps in User mode, and that most modern OS's do not map portions of the physical address space for user processes. So, just in case, you probably still need to check the OEM, device ID and OS version. And whatever your need is, you might want to put in a request to PalmSource and/or the OEM's to provide supported API's for such. I'd like to see official support for reading the high resolution CPU cycle counter(s), the display vertical refresh counter(s) if possible, and for setting oddball serial port baud rate dividers, for instance. Any others?
