You may encounter Out of Memory errors when installing a Newton OS System Update Patch if your Newton System Heap is fragmented due to the length of time you have been using your Newton device.
During installation, the System Update Patch is stored in flash memory as the Newton device prepares the new software. The update is then moved to System Ram. A contiguous free area of System Memory is therefore required for installation of the update.
To defragment your System Heap, you may need to perform a Hard Reset as outlined in your User's Manual.
Warning
A hard reset erases all data and information in the MessagePad's internal memory. This includes any applications that were already on your MessagePad when you bought it (including the Newton Tour and HW Instructor). It also erases information you have stored, such as name cards, notes, calls, and pages in the Date Book. This procedure does not remove the MessagePad's built-in programs, operating system software, or software updates.
To do a hard reset:
1. Remove any storage or application cards that are inserted in the MessagePad.
2. Press and hold down the Reset button and then press and hold down the Power switch.
3. Hold down the Reset button for two seconds, then release it while continuing to hold down the Power switch. Continue holding down the Power switch until a message appears asking if you want to erase you data completely.
4. Tap Yes. Another slip appears telling you that all of the data will be erased.
5. Tap OK.
All the information (including any packages you loaded and other applications that are not built in) is erased and your MessagePad reverts to the defaults set at the factory. This procedure may take several minutes.
