- MC68040 ToolKit - copyright (c) 1996-7 Douglas Little
- *~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~*
-
- The MC68040 ToolKit is currently being developed as a complete software
- driver for the Afterburner040 accelerator card. Every facet of the card
- is accessible via these tools, and many extra features are included to
- improve backward compatibility with older or more 68030-specific software.
- An array of special options are also available, allowing the user to push
- the machine's performance beyond it's normal expected limitations.
-
- *-----------------------------------------------------------------------*
-
- A brief list of features include:
-
- * Quick and easy configuration of FastRAM & FastROM. No fiddling about.
- * FastRAM is automatically detected and made contiguous at $01000000.
- * Direct control over processor caches at boot-up/warmstart time.
- * System page copyback cache option increased performance.
- * System page FastRAM option for increased performance.
- * Drive-specific cache-flushing to prevent 'dirty' DMA cache entries.
- * Drive-specific cache 'locking' for wider compatibility with HD drivers.
- * Drive-specific internal data buffering for safer SCSI DMA transfers.
- * Configurable FastROM facility, with GEMRAM simulation for WINX users.
- * Reset-resident FastROM feature for ready-patched TOS on a warm start.
- * FastRAM read/write fault checking, with user-configurable cache control.
- * Datacache address-space masking feature for quicker screen redraws.
- * Instruction cache can be made available from a warm-reset.
- * FastROM can be write-protected, or left in a read/writeable form.
- * MagiC compatible - also allows MagiC to be loaded into FastRAM!
- * Blitter disabled & locked to prevent FastRAM blit operations.
- * Special NOVA graphic card compatibility feature.
- * Screen blanker enabled when NOVA graphic card is used.
- * VDI rastercopy patch prevents blitter from trashing ST-RAM.
-
- *-----------------------------------------------------------------------*
-
- Some software benefits to be gained from using these tools:
-
- * Cures cache / DMA-buffering problems for HD drivers under TOS & MagiC.
- * MagiC (4.02) can be run happily from both ST-RAM & FastRAM.
- * TOS 4.04 ROM can be installed in FastRAM and made reset-resident.
- * WINX can now be run with original TOS entirely in FastRAM.

-
- The interface is based on the windowing system originally developed for
- Apex Alpha by Black Scorpion Software LTD, and can run in any truecolour
- resolution available. Configuring BlowUP or FalconScreen with custom TC
- modes allows the program to be used in 512x384, or whatever you are able
- to achieve on your machine with your monitor. Stock Falcons with no
- screen expanding software installed will default to a rather chunky low-res
- 320x240 mode.
-
- Note: ScreenBlaster will not work with this program, since SB contains
- a bug which prevents clean resolution changes in any program - except
- the Desktop. Future upgrades will incorporate a bypass which will at
- least allow 416x312 with no screen enhancer installed, or when SB2 or
- SB3 is detected as being resident.

-
- A Falcon040 mailing list has been set up by Johan Klockars and Magnus
- Kollberg to cater for all 68040 based Falcon users - especially ones
- with problems needing fixed, or questions needing answered. If you do
- have an Afterburner or equivalent card, join the rest of us by sending
- an email to:
-
- <falcon040-request@rand.thn.htu.se>
-
- ..with 'subscribe' as the subject line. This will add your name and email
- address to the automatic mailing list, making you a member.
-
- All subsequent mail traffic from users of the mailing list will be
- forwarded automatically to your own address, and your replies and any other
- contributions you wish to make should be sent to:
-
- <falcon040@rand.thn.htu.se>
-
- ..which is the actualy mailing list address, and which will forward your
- messages to all other members of the list.
