- REQUIREMENTS
- Any Amiga® (compatible) computer with at least OS2.04 and 68020+ cpu.

- DESCRIPTION
- Did you ever had the problem, that you had several Zip® disks, each of them
- probably formatted or partitioned differently with different filesystems like
- FFS, SFS, PFS, CrossDOS, etc? And each time you change the disk you had to
- mount another device driver to access the disk? Wouldn't it be much easier
- just to insert the disk and let the Amiga automatically mount the new driver
- if necessary?
- Or do you have disk drive, that cannot be accessed during booting, so that you
- have to mout the drive "by hand" using a mountfile?
- AutoMounter does exactly all these things. It will monitor any drive you
- configure for disk changes. Every time you insert a disk in one of these
- drives AutoMounter will check if the disk matches any of the already mounted
- devices in the system, and if this check fails it will try to mount it. It
- doesn't matter if the disk uses a filesystem you didn't use before, because
- AutoMounter will try to read the disk's RDB and load the desired filesystem
- from there. This also works for MS-DOS formatted disks, which have no RDB, but
- it requires either CrossDOS or FAT95.
- Please note that the CrossDOS/FAT95 support is very simple. Things like
- partitions in extended partitions and similar things are not supported. I
- think there is no need for such things because of two reasons:
- 1. most changeable media are Zip disks, which only have one partition
- 2. AutoMounter is no filesystem, just a little tool doing a job in the
- background.
- If you really ever have a disk with several partitions of which not all can be
- mounted by AutoMounter, then please contact me and I will try to change that.
-
- A hint for IOBlix users:
- There is no need to specify the device entries in the tooltypes of AutoMounter
- for Parallelport ZIP-Drivers connected to the IOBlix as long as you start
- SetupIOBlix with the AUTOMOUNT option. IOBlix' AutoMount.demon will use
- AutoMounter as soon as it is running. Without the AutoMount.demon you will of
- course have to handle the drives connected to the IOBlix as any other device.
-
-
- USAGE
- You can start AutoMounter from either Workbench or Shell with the following
- options, although Workbench is more suitable:
-
- POLLTIMEOUT/K/N,FAT95/S,DEVICE/M
-
- POLLTIMEOUT/K/N: set the timeout (in seconds) for polling ancient drivers for
- disk changes. Default value is 5 seconds.
-
- FAT95/S: use L:fat95 instead of L:CrossDOSFileSystem for MS-DOS formatted
- disks. This is necessary, because the version of CrossDOS delivered with
- AmigaOS 2.04+ doesn't support long filenames, but not everybody has FAT95
- installed. So if you have MS-DOS formatted disk, but you don't own the
- commercial version of CrossDOS (V6.x, V7.x), then set this option to use
- FAT95.
-
- DEVICE/M: set a device to be monitored for disk changes. Each device entry
- must be given using the following template:
-
- DEVICE/A,UNIT/A/N,MAXTRANSFER=MT/K,DEFFATNAME,POLL/S
-
- DEVICE/A: Exec style device name of the device to be monitored
-
- UNIT/A/N: unit number of the device
-
- MAXTRANSFER=MT/K: some devices don't like the standard value 0x00ffffff
- for MaxTransfer. If you notice any problems then use this option. The
- value must be given in hexadecimal notation, starting with "0x". Some
- IDE/ATAPI drives will choke for other MaxTransfer values than 0x0001fe00.
- Default value is 0x00ffffff.
-
- DEFFATNAME: MS-DOS formatted disks don't have an RDB, so they cannot tell
- AutoMounter the name under which the drive should be mounted. This option
- only affects MS-DOS formatted disks and has no meaning for Amiga formatted
- disk with RDB. This name defaults to "FATC".
- Note: This name must *NOT* include a trailing ":"!!
-
- POLL/S: use this option for those device drivers, that don't support disk
- change notification. These drivers will be asked every <POLLTIMEOUT>
- seconds for a disk change. This option should only be used if disk
- changes are not noticed automatically.
-
- Examples:
- DEVICE=cybppc.device 2
- Monitor cybppc.device unit 2 (my Zip drive) for disk changes.
-
- DEVICE=cybppc.device 2 ZIPC
- Monitor cybppc.device unit 2 for disk changes, but use ZIPC as drive name
- for MS-DOS formatted disks. Usage of fat95 instead of CrossDOSFileSystem
- for MS-DOS formatted disks depends on the global flag <FAT95>.
-
- DEVICE=very_ancient.device 0 FAT poll
- Monitor very_ancient.device unit 0 for disk changes, use FAT as drive name
- for MS-DOS formatted disks. Because very_ancient.device doesn't support
- disk change interrupts, poll it every 5 seconds for a disk change. Usage
- of fat95 instead of CrossDOSFileSystem for MS-DOS formatted disks depends
- on the global flag <FAT95>.
-
- If you start AutoMounter from Shell you must surround every DEVICE
- specification with quotes ("), because of the spaces in the specification
- (e.g. AutoMounter "dev1.device 0" "dev2.device 4 poll")
-
- For the case you have two disks with different geometry, but with the same
- device name in the RDB (for example two ZIP disks) AutoMounter will change the
- name of the newly mounted device that it is unique in the system. That means
- it will append ".0", ".1", ".2", etc to the RDB-saved device name, until the
- device name is unique. You will have two different DOS-devices afterwards for
- the same disk drive, but you will be able to access both disks without the
- need of a remount tool like SCSIMounter or Mounter (supplied with OS3.5/3.9).
- Additionally this behaviour is much safer than unmounting the old drive.
-
- You can start and quit AutoMounter at any time. To quit AutoMounter simply
- start it a second time.
-
- Additionally there are three support tools for AutoMounter: AddAutoDevice,
- RemAutoDevice and ListAutoDevices. With the first two tools you can
- dynamically add or remove a device from disk change monitoring.
-
- The usage template for AddAutoDevice is the same as for every DEVICE tooltype
- of AutoMounter. AddAutoDevice will print the result of adding the device for
- monitoring, either success or failure.
-
- RemAutoDevice just needs the device name and the unit number to remove from
- monitoring. RemAutoDevice will print the result of removing the device from
- monitoring, either success or failure.
-
- ListAutoDevices will print a list of all currently monitored devices.
-
-
- INSTALLATION
- Copy AutoMounter where ever you want, but SYS:WBStartup is a very good place.
-
-
- KNOWN BUGS
- - cybppc.device seems to tend to crash after removing a device from
- monitoring and changing the disk afterwards. I don't know why this happens
- and if this applies for all of phase5's devices. But I think this not a real
- problem, since all of phase5's devices have a built-in mounter, so there
- should be no real need to run AutoMounter on these devices.
- - 1230scsi.device (Blizzard 1230/1240/1260 SCSI module) doesn't increment its
- diskchange counter. AutoMounter isn't affected by this anymore (V37.2), but
- of course this is a serious bug in phase5's device drivers!

- HISTORY
- 37.1 (21.01.2001):
- - initial Aminet release
-
- 37.2 (12.02.2001):
- - devices and units are now checked if they are changable media. Drives like
- harddisks or CD-ROMs will be rejected, because they are either not
- changable or they will never contain a valid RDB.
- - recognition of MS-DOS formatted disks is much better now. MBR and
- partition table are now searched for valid entries before trying to mount
- a new device.
- - new option FAT95 now enables support for fat95 filesystem instead of
- CrossDOS.
- - ListAutoDevices contained a wrong version string. Damn quick hacking :)
- - drivers that need polling to detect a disk change will now get a command
- sequence that is similar to the shell command DiskChange to make them
- recognize the new disk.
- - MaxTransfer value can be set now, in case some stupid device drivers
- cannot handle transfers >=128K.
- - mounting FAT formatted disks was completely broken and caused immediate
- crashes. This is fixed now, CrossDOS and FAT95 are fully supported now.
-
- 37.3 (23.08.2001):
- - a driver would have been over and over again when the disk geometry could
- not be determinded for some reason. This is fixed now. Even empty drives
- are monitored correctly now.
