Re: PRIME: Memory Map Message #2 Posted by Han on 6 Nov 2013, 10:59 a.m., in response to message #1 by Harold A Climer
There is no "re-installing" of the OS. The OS sits in a pre-defined location, and any "formatting" done excludes these pre-defined locations. Theoretically, nothing the user does will ever affect those memory blocks in which the OS is stored, including formatting.
There is an INI file here: Old HP Prime firmware
This will give you an idea of certain memory boundaries.
As for memory boundaries for programs and variables, I am under the impression that they all share the same block.
Lastly, there is RAM and FLASH. RAM is for use by the calculator like RAM on a PC. Flash is where the OS is stored, as well as user variables, settings, programs, etc. It serves the same purpose as a hard drive on a PC. My understanding is that nothing is "saved" into flash until the HP is turned off -- this is why there is a slight delay when turning off the HP. It is writing to FLASH before it shuts down.
