- MC68040 ToolKit - typical configuration
- *~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~*
-
- Described here is a typical configuration for a machine equipped with
- FastRAM and both IDE and SCSI drives. It is also assumed the machine is
- using normal TOS and some version of NVDI. AHDI is being used as the
- auto-boot driver, with HDDriver in the auto folder - running after the
- 68040 driver program.
-
- Floppy: drives A->B
- IDE: drives C->F
- SCSI: drives G->J
-
- * Since this machine uses Floppy disk and SCSI devices, we should enable
- one 'DMA/FRB' button for each of these drives. This prevents fundamental
- problems with the CPU caches and DMA. Don't bother with your IDE drives.
-
- * It is definitely advised that you enable the corresponding 'D-CACHE'
- button for each Floppy/SCSI drive as well. This ensures the datacache
- does not interfere with DMA disk transfers. Some people might be able
- to get away without using this safety feature, but it is not advised.
- Again, don't bother with IDE - only mark your Floppy and SCSI devices
- with these buttons.
-
- * The 'Buffer Internally' button should be enabled to protect all drives
- marked as DMA/FRB from corruption due to illegal FastRAM DMA transfers
- under TOS.
-
- * Enable the 'Sector READ/WRITE' option or the disk patching will not
- work.
-
- * Enable all of the buttons on the 'RAM' dialog for speed.
-
- * Enable '32-Bit FastROM' and 'Cacheable ROM' for more speed.
-
- * Enable 'Resurrect PMMU' and 'Bootstrap Loader' to make FastROM fully
- reset-resident (like Magic!).
-
- * Activate the 'Enable I-Cache' button to make sure the instruction cache
- is working after boot time. Do not turn on the data cache, or HDDriver
- will cause problems when logging your SCSI partitions. Place ECACHE40.PRG
- after HDDriver in the auto folder to do this properly. If you don't have
- HDDriver in your auto folder, then you can use 'Enable D-Cache' quite
- safely.
-
- Any other options are entirely up to the user, but this would be enough
- to get the system working properly with the most useful features. All
- buttons not indicated here are assumed to be disabled for this example.
