Short: Chip memory cache mode fine tuning tool Author: thor@math.tu-berlin.de (Thomas Richter) Uploader: thor@math.tu-berlin.de (Thomas Richter) Version: 40.2 Type: util/boot Requires: Os 2.04, a 68020/68851, 68030, 68040 or 68060 with a working MMU ----------------------------------------------------------------------------- MuFastChip sets the caching mode of chip memory to "imprecise nonserialized" and will therefore speed up chip memory accesses a bit. For that, it requies a 68040 or 68060 MMU as this access mode is not available on the 68030 or 68851. It won't crash on these MMUs, but will effectively do nothing at all. This tool is *NOT* required (or will do nothing) if an mmu.library based 68040 or 68060 library is installed, or if the 68040/68060 library installed is smart enough to handle this itself on startup. MuFastChip replaces certain third-party products that hack the MMU themselves and are therefore incompatible to the MuLib and no longer recommended. ------------------------------------------------------------------------------ This tool is part of the MMULib distribution. To find out more about the mmu.library and its goals, download util/libs/MMULib.lha. ------------------------------------------------------------------------------ Quick installation notes: - Copy LIBS/mmu.library to LIBS: - Copy "MuTools/MuSetCacheMode" to C: - Study the "MuSetCacheMode.guide" to find out how it works. ------------------------------------------------------------------------------ The THOR-Software Licence (v2, 24th June 1998) This License applies to the computer programs known as the "mmu.library" and "MuFastChip". The "Program", below, refers to such program. The "Archive" refers to the package of distribution, as prepared by the author of the Program, Thomas Richter. Each licensee is addressed as "you".

However, the following methods of distribution involving payment shall not in and of themselves be a violation of this restriction: (i) Posting the Program on a public access information storage and retrieval service for which a fee is received for retrieving information (such as an on-line service), provided that the fee is not content-dependent (i.e., the fee would be the same for retrieving the same volume of information consisting of random data). (ii) Distributing the Program on a CD-ROM, provided that a) the Archive is reproduced entirely and verbatim on such CD-ROM, including especially this licence agreement; b) the CD-ROM is made available to the public for a nominal fee only, c) a copy of the CD is made available to the author for free except for shipment costs, and d) provided further that all information on such CD-ROM is redistributable for non-commercial purposes without charge.
