Short: Releases 28K of ChipMem on OS 3.1.4 Author: thorfdbg@alumni.tu-berlin.de (Thomas Richter) Uploader: thorfdbg alumni tu-berlin de (Thomas Richter) Type: util/boot Version: 46.1 Requires: AmigaOS 3.1.4 Architecture: m68k-amigaos ----------------------------------------------------------------------------- New in V46.1: This is the first Aminet release ----------------------------------------------------------------------------- What is the purpose of this utility: Starting with Os 3.1.4, exec V46 reserves the low 16K of ChipRam for operating system purposes. In particular, MAC emulators require this memory, and previous utilities to keep this memory area free of Os structures required deep knowledge of the exec coldstart mechanism and may have failed with upgraded Os variants. Hence, starting from Os 3.1.4 on, exec keeps the Os out of this area. This has the drawback that less chip memory remains available for a handfull of critical programs that require as much ChipRam as possible. Luckily, exec V46 comes with a mechanism to release this memory. Or, to put it short: MoveLow is MuMove4K backwards, just without the hacky part. The exec.library version that comes with Os 3.9 will also reserve the lowest 16K for emulator purposes. It is, however, not compatible to MoveLow. ----------------------------------------------------------------------------- Installation: Just this utility into your C: folder, and execute it if needed, potentially in your startup sequence. It will trigger a reboot itself. ------------------------------------------------------------------------------ The THOR-Software Licence (v2, 24th June 1998) This License applies to the computer programs known as the "mmu.library" and its sources.
