- A2091Turbo V1.3
- A4000 & A2091 together forever...
- (c) 1993 by Fabio Caruso
- PD software freely distributable.
-
- You bought the A4000 and you have also an A2091 built-in and you
- noticed that this controller is very slow on your A4000 (approx.50kb/sec)
- ? Well, this is the program for you... In fact it patches dos.library functions
- Read and Write, so that when the A4000 reads from hard disk to 32-bit
- ram, data will be copied to a 128k buffer first, then in their final place (in
- 32-bit ram); during Write the process will be executed backwards.
- It's important to observe that the program needs Kickstart 2.04 or later,
- because it uses some functions that not work on OS 1.3 (dos-offsets
- structure, 24-bit Dma memory allocation and cache's control); you must
- have also at least 128k bytes of 24-bit Dma ram free, better: the prog uses
- A2091 ram, if you have some, if not it uses chip ram. Also this new re-
- lease (A2091Turbo V1.2) has an advanced cache's control: in fact when it's
- possible it keeps instruction and data (or 040 copyback) caches on!!
- It's guaranteed to function on A3000/A4000 machines in conjunction with
- A2091 controller, but probably it works as well on an accelerated A500
- with A590 controller and on any Amiga with an hard drive and an
- accelerator that has 32-bit ram out of 24-bit space ($000000-$ffffff)
- and that not supports Dma directly on the board.
-
- To install A2091Turbo you must digit:
- A2091Turbo <devices list> (ex.: A2091Turbo dh0: dh1: dh2:)
-
- Important: devices names must be partitions names not volumes names,
- better, the names in your mountlist not the names that appear on your
- Workbench window. Names can be uppercases or lowcases: it's the same.
- There's no problem if a device in the list not exists: it will be not
- patched; and, of course, if you patch for two times the same device,
- the program will recognize this and it does nothing.
-
- To list patched devices digit:
- A2091Turbo list
-
- To remove A2091Turbo digit:
- A2091Turbo quit
-
- Enjoy with revival of your A2091 and try anything!! I believe the program
- is bug's free!!!

- If you have a similar problem and you need a customized version please
- specify:
- computer name, hard drive, controller, accelerator, ram installed (16 &
- 32-bit), all the boards installed on your system, startup-sequence,
- mountlist or autoboot partitions data (use HDToolBox or similar to read
- it), and all you know about your problem and, certainly, some money for
- shipping charge. Thank you.
