Description Complète :	=========================================================================== - Xpand v0.2b for TI Voyage 200 - AMS 2.07/2.08/2.09/3.01/3.10 Copyright (C) 2002-2005 Olivier Armand - All rights reserved. =========================================================================== ========== Disclaimer ========== You are not allowed to re-distribute this package or any part of it without the authorization of the author. Freeflash is a type of software which needs to be kept up-to-date. Limiting its re-distribution is the best way to ensure this. Give a link to ticalc.org's archives instead of copying the package. This program is provided "as is" without warranty of any kind, either express or implied. In no event can the author be held responsible for any damages (including, but not limited to, hardware failure, data loss and/or certificate memory corruption), whether or not they result (directly or indirectly) from the use of this program. Use this program at your own risk. What is Xpand? =============== Xpand is an OS patch to use as Archive Memory the 1728kb (~1.69Mb) of FlashROM reserved for the Flash Apps. 2688kb (~2.62Mb) of Archive Memory will be usable after the patch. (Remove 64kb from these figures for AMS 3.01, and 128kb for AMS 3.10 and higher). Using Xpand =========== THE PATCH WILL BE IRREVERSIBLE. The only way to remove its effect is to send a new OS to the calculator. Run Xpand once from the Home screen on a stable calculator (without any resident program installed, preferably after a reset). The Garbage Collection made at the end of the patch can take a few seconds. You need to patch the OS only once: you will not need to run Xpand after each reset. You can check that your archive memory has been 'expanded' by running getconfg() in the Home screen: the value of 'Archive size' at the end of the list should be higher than before (see 'What is Xpand?' above). Once the OS is patched, its checksum is invalid; you will not be able to send the OS from your calculator to another V200. Caution, you may lose some of your archived files when sending a new OS to the calculator once Xpand have been installed. Backup your files before flashing the calculator, and patch the new OS after its installation. What was wrong with version 0.1? ================================ Xpand has been removed from distribution for 9 months, because of an important bug that made the calculator crash when trying to install a lot of Flash Apps with Xpand installed. The problem has now been fixed, Xpand should not interfere anymore with Flash Apps installation. The execution protection in FlashROM memory seems to be buggy on the Voyage 200 when trying to protect a part of the range address 0x400000-0x500000. Perhaps this is why TI has created the limit of available archive memory that Xpand breaks (for the same reasons as the limit on TI89/TI92+ HW1 calculators broken by MaxMem). An interesting feature added by version 0.2 to correct the problem is that the execution protection in FlashROM memory has been completely removed. Anything can be executed in archive memory after Xpand's installation.
