- PLEASE READ THIS TEXT VERY CAREFULLY!!
- ======================================
-
- IF YOU ALREADY FEEL FAMILIAR WITH GEMAR, YOU SHOULD AT LEAST READ THE
- SECTION 'HISTORY' AND 'RESTRICTIONS AND KNOWN ERRORS'.

- ATTENTION PLEASE: !!!!!!!!!!!!!!!!
- Due to minor changes, the tapes with a version number greater than 1.10
- cannot be recognized by GEMAR versions smaller 1.10. However, version 1.10
- recognizes the tapes of older versions.
- There will be no loss of data, they will be save on the tape. Nonetheless,
- such a tape must be read by new versions.

-
-
- GEMAR is a shareware product, which means that GEMAR may be copied and
- used freely by private users under the prerequisite that all data files
- remain unchanged.
-
- I'm sorry GEMAR has not all functions in the public Version.
- In Germany most users do not pay for Shareware, so I decided to make
- differences between the registered and the public version to get those
- users to pay the fee.
-
- Persons who use GEMAR frequently, must be registered and have to pay:
-
-
- 1.) Registration for $ 60
- A complete version of GEMAR, updates upon sending the original
- disc as well as an envelope including sufficient postage - alter-
- natively upon paying $ 10.
-
- 2.) Registration for $ 90
- A complete version of GEMAR, three updates automatically after
- publication.
-
- Please take care for any charges for order checks, so these amounts will
- arrive me!
-
- The registered version has a few extended capabilities:
-
- -Image-Backups of non TOS partitions (OS9, Spectre, Minix ...)
- -Batch-capabilities for automation of repeating actions
-
- In addition, the registered user will receive a printed manual
- with a detailed documentation on GEMAR.
-
-
- THE REGISTERED VERSION MUST NOT BE GIVEN TO THIRD PERSONS !!
-
- Right now the registration fees for professional users is $ 180.
- Also available are special discounts for multi-users.
-
- Please use the form in the file REGISTER.TXT for registration.
-
- A commercial trade can only be done if a written permisson has been
- given. This also includes Public-Domain discs.
-
- After sending a 3.5" disc and an envelope with sufficient postage
- you will receive the latest version of GEMAR.
-
- LIABILITY
-
- Me, Steffen Engel, cannot take any liability for direct or indirect
- problems due to the use of GEMAR.
-
- GEMAR has been programmed and tested with maximum care, but I cannot give
- warranty for GEMAR to be free of errors.

- It is possible to adjust GEMAR such, that only the commands of the
- corresponding streamer will be used according to the SCSI norm.
- Just in case: If the streamer does not work with GEMAR, it might be
- possible for me to modify GEMAR properly. Therefore, I would need
- to have the manual with the SCSI-commands.
-
- If a new configuration file exits which is not according to GEMAR I would
- like to ask you to send me the used parameters. With this I can also
- attache the right parameter file so that not everybody has to identify
- his new adjustment. Basically it is sufficient to send the file
- 'Streamer Adjustments' as well as the 'Data Rate' and 'Max. Read' from
- the file 'Backup Adjustments'.
-
-
- GEMAR UNDER MULTITASKING:
-
- Principally GEMAR works under Atari Multi-Tasking Extensions
- (MiNT, MultiTOS, MultiGEM, Mag!X).
- However, Backup/Restore should never be done while another process is
- running.
-
- There are three significant reasons for that:
-
- 1.) Speed:
- All available computing power is necessary to supply
- data to the streamer and simultaneously read data from the
- hard disk. For this it is completely unimportant whether an ST, TT,
- Falcon, or anything else is used.
-
- 2.) Need for Storage:
- In order to carry out an efficient buffering of the data, GEMAR need
- quite some storage. Only this way the streamer can be fed with data.
-
- 3.) Data Protection
- If another program modifies the data on the hard disk, while GEMAR
- is working, a consistent backup cannot be guaranteed.
- Hence, because of reasons of data protection no other program
- should be running that may save, delete, or modify files.
- As soon as there is a possibility of refusing an access of other
- programs while GEMAR is working, it will be implemented in GEMAR.
-
-
- RESTRICTIONS AND KNOWN ERRORS:
-
- The english version is not english at all, I'm sorry.
- Some internal Strings are in german, due to the concept of MAGIC.
- Never mind, they are not so hard to read.
- I'm thinking about a way to transfer the internals Strings to the used
- language without changing MAGIC's concept.
-
- The hard disk software made by LACOM does not create Atari-compatible
- partitions within version 3.2a. Therefore problems may occure during
- Image-backups.
-
- A backup, stored at the very end of a tape can only be carried over to
- another tape if the tape was saved with Quick-File-Access capabilites.
-
- Some users have problems with backups that have been restored with
- Quick File Access (Seek). In this case the Quick File Access should be
- turned off during the restore procedure. Unfortunately, until now it has
- been impossible for me to reproduce this error, hence there is no
- repair mechanism known to me.
-
- GEMAR should work with virtuall memory quite well. But I must say, that
- this memory has to be located over phystop. With OUTSIDE it's possible to
- add the virtual RAM below phystop. In this case, GEMAR's program-flags
- should be set to 'Load to TT-RAM' and 'Malloc from TT-RAM' off.
-
- GEMA uses TAS to check the Semaphor Flock. This Opcode may cause Problems on
- some Versions of the GE-Soft HyperCache due to an error of the Hypercache.
- I cannot see a way to replace this opcode so on Problems with your
- HyperCache please contact GE-Soft for correction.
-
- FUTURE OUTLOOK:
-
-
-
-
- HISTORY:
-
- -2.0 dated 10/15/93
- -first english release
-
- -2.2 dated 03/05/94
- -Hypertext Helppages
- -PlugIns
- -Image-Backups of whole Harddisks can be performed.
- -Cut/Copy/Paste in Editables (thanks to Dirk Steins)
- -For the HyperCache GEMAR can be set to no use of TAS, when a cookie 'nTAS'
- ist installed. Install SET_NTAS in your AUTO-Folder for this
- -For the User there is no more differantiation between Falcon and TT-SCSI
- -When a tape ist loaded, parameterfiles can't be loaded due to security for
- the actual parameters
- -several Bugfixes (TAR-Headers are correct again, disabled icons where
- selectable in GEMAR 2.01, no more crashes under MultiTOS, ...)
