=========================================================================== FS1541 v0.5 =========================================================================== (C) Copyright 1996 by Michael Krause. This production is FreeWare! =========================================================================== --------------------------------------------------------------------------- >>> INTRODUCTION --------------------------------------------------------------------------- Forget all those nasty tools to read files off 1541 disks: FS1541 is a full-blown AmigaDOS file system, which processes the CBM 1541 disk format. The CBM 1541 floppy drive has been the standard disk drive for the C64 computer series, and many people still have disks flying around. For processing disks directly, you need the >Catweasel< floppy disk controller and a 5.25 inch drive, without it you have to get "fmsdisk.device" from Aminet or somewhere, which lets you operate on ".d64" disk image files. --------------------------------------------------------------------------- >>> INSTALLATION --------------------------------------------------------------------------- Copy "1541-handler" to L:. Add the following lines to "DEVS:MountList": CBM0: Handler = L:1541-handler Stacksize = 4096 Priority = 10 GlobVec = -1 Mount = 1 Startup = "DEVICE multidisk.device UNIT 1" # Explanation of options: D=DEVICE/A Name of a trackdisk.device compatible device. Supported and tested are "multidisk.device" and "fmsdisk.device". U=UNIT/N/A Exec device unit. 0 or 1 for "multidisk.device", see docs for "fmsdisk.device". F=FLAGS/N Exec device flags. Defaults to 16. NS=NOAUTOSCAN/S Don't read complete disk after insertion. I=INTERLEAVE/N Sector interleave when writing data. Defaults to 4. --------------------------------------------------------------------------- >>> USAGE --------------------------------------------------------------------------- Issue the command `mount cbm0:', and insert disks. Write support is currently very rudimentary (if not non-existent), don't rely on it working correctly! There are two so-called "virtual" files, which don't appear in the directory and serve special purposes: $d64 Access the .d64 file corresponding to the current disk. E.g. you can use `copy cbm0:$d64 ram:dsk.d64' to create .d64 images of your disks very easily! Disk.info Provides a disk icon for Workbench. --------------------------------------------------------------------------- >>> HISTORY --------------------------------------------------------------------------- See accompanying file "ChangeLog". --------------------------------------------------------------------------- >>> FUTURE --------------------------------------------------------------------------- There is still a lot to do, most important are complete write support and a virtual file "$" which contains the disk's directory as displayed by a C64, and some other goodies. I'll be back! --------------------------------------------------------------------------- >>> WHAT ABOUT THE SOURCE CODE? --------------------------------------------------------------------------- FS1541 was entirely written using GCC 2.7.2 from the ADE as found on ftp.ninemoons.com. The source code is a good example of how AmigaDOS handlers work. --------------------------------------------------------------------------- >>> WHERE TO FIND THE AUTHOR: --------------------------------------------------------------------------- Michael Krause Mannesallee 24 21107 Hamburg rawstyle@blackbox.dame.de ii7349@fh-wedel.de http://www.szczecin.pl/~rawstyle/ --------------------------------------------------------------------------- >>> LEGAL MUSH! --------------------------------------------------------------------------- This program is FreeWare, which means that it may be spread as long as nothing is charged for it. It may not be enclosed in commercial packages. The one and only exception to this rule is the great >Catweasel< floppy disk controller, which includes this file system. The controller lets you use standard PC disk drives to read and write PC and Amiga DD/HD disks at a much higher speed than provided by the Amiga custom chips. When used with a 5.25 inch disk drive, you can use this file system to process 1541 disks directly. Neither the author nor any other individual, besides perhaps the user himself, can be held reliable for damages caused by (mis-)use of this software!
