- Short information about "macformat"
- -----------------------------------
-
- When you use the Macintosh-Emulator "Executor" for Linux, you may want
- to format floppy disks in macintosh format. (For technical reasons,
- only the 1.44 MB format is supported by this little program, because
- this format uses the same low-level format as the PC 1.44 MB format.
- The 800 KB format is _not_ supported!)
-
- The simple way is to get a macintosh, format a high density floppy disk
- on it, insert the disk into the floppy disk drive of your Linux box and
- say "cat /dev/fd0 >MAC_DISK". Whenever you need a macintosh formatted
- disk now, simply say "cat MAC_DISK >/dev/fd0" - that's all.
-
- The program "macformat" principally does the same, but just writes the
- blocks that are really needed to tell the Macintosh that this disk is
- a blank disk. Additionally, you can choose a name (disk label) for the
- freshly formatted disk. Note: The disk has to be low-level formatted
- first; this can be done with "fdformat /dev/fd0". But you only have to
- low-level format it the first time (or buy pre-formatted ones). It
- doesn't make a difference it you have previously used it with other
- file systems, so you doesn't have to 'fdformat' a disk previously used
- with MS-DOS etc.
-
- To use "macformat", simply insert your disk to be macintosh-formatted
- and type:
-
- macformat /dev/fd0
-
- After a few seconds (not longer than five seconds), you have a freshly
- formatted macintosh disk with the disk label "Empty" - ready for use
- with "Executor" or a real Macintosh.
-
- If you want to format your disk giving an other disk label to it, just
- type:
-
- macformat /dev/fd0 "New Disk"
-
- The new disk will then get the disk label "New Disk". For some reason,
- the length of the disk label is limited to 10 characters, while a real
- Macintosh accepts disk labels with a length up to 27 characters, but
- my disk image had a disk label of exactly 10 characters. If you think
- you can change it, just take the source (included) and fiddle around
- with it. Please drop me a note if you can change it to 27 characters.
- (I had no success by simply changing the length limit from 10 to 27,
- maybe there's another byte on the disk image that has to be changed.)
-
- The other two programs in this package, "bin2c" and "getdiskblocks",
- are not needed for normal use. You will only need them if you want
- to build a "macformat" binary with data blocks from an other disk
- image. The "getdiskblocks" just writes two files with the disk blocks
- needed, the "bin2c" converts them to C source, so that there is only
- a single binary and no extra data files needed. Just look at the sources,
- if you want to play with this.
