- MC68040 driver - copyright 1996 Douglas Little
- *~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~*
-
- The 68040 driver program (68040DRV.PRG) is a user-configurable TSR
- program which sets up the 68040 processor's internal PMMU (programmable
- memory management unit) to allow FastRAM to be used, as well as more
- advanced options like FastROM and 'copyback cache' modes. It also
- handles other potential difficulties like troublesome harddisk drivers
- and operating systems which try to use DMA/SCSI devices illegally with
- FastRAM.
-
- The driver should always be run from the auto folder, and can be set
- up manually using the configuration tool (68040CFG.APP). You could make
- several different copies of the driver file, under different filenames,
- with different configurations, and use them along with a boot manager
- (like Stoop or Xboot) to allow quick switching between different machine
- setups. This can save a great deal of time when there are one or two
- programs which don't like a particular configuration, and you need to
- change over in a hurry.
-
- Place the driver program as early as possible in the auto folder, but
- feel free to experiment if the need arises. You should also install
- TKBUBBLE.PRG if you use lots of other auto folder software, to prevent
- the 68040 driver from being 'patched out'. It is normally wise to
- place TKBUBBLE after NVDI if it is installed, since very few system
- calls actually get past NVDI. This is simply because NVDI replaces most
- of them.
-
- See documentation on 68040CFG.APP for details on how to set up the
- driver program.
-
- The 68040DRV.RAW file is just a plain vanilla (backup) version of the
- main 68040DRV.PRG program. Apart from the RAW file being unconfigured,
- they are otherwise identical in every way.
