DF0:C/CSA-MMR SRAM DRAM
You may need to specify the speed of the RAM....I cant recall if I left it blank.....
"The DRAM option checks for the presence of the CSA Mega-Memory DRAM daughterboard,configures the DRAM controller, tests the DRAM memory, and adds the DRAM to
the system as fast memory. The clock frequency of the Mega-Midget Racer is needed to
properly configure the DRAM controller. The default is 25.00 MHz and can be specified
as any value between 20.00 and 33.33 MHz. Information about the type, size, and speed
of the DRAM chips and the number of banks is automatically retrieved from the jumper
settings on the daughter-board."
CSA-MMR:
The CSA-MMR program is responsible for configuring and installing all of the Mega-
Midget Racer’s resources. This includes determining which processor and co-processor
are installed, and configuring, testing, and installing any 32-bit RAM.
The CSA-MMR program should be run from the CLI or Shell, or put in the startupsequence
on a bootable disk. The command-line syntaxes for proper program invocation
are shown below (square brackets enclose optional items):
CSA-MMR [SROM] [SRAM] [DRAM [freq]]
CSA-MMR -i
CSA-MMR -v
CSA-MMR -?
where:
CSA-MMR is the name of the program
SROM copies the Amiga ROM kernel into the Mega-Midget Racer’s 32-bit
SRAM, if present
SRAM adds the Mega-Midget Racer’s 32-bit SRAM to system memory, if
present and if not all used by SROM feature
DRAM configures CSA Mega-Memory DRAM daughter-board and adds 32-bit
DRAM to system memory
freq is the clock frequency of the Mega-Midget Racer. Values may range
from 20.00 to 33.33, in MHz (default is 25.00). This value is
needed to properly configure the CSA Mega-Memory daughter-board.
-i displays system information, including a list of installed memory
regions and the current CPU cache configuration
-v displays the program title and version number.
-? displays a brief description of how to invoke the program.
The Amiga operating system automatically determines if a higher level processor is
installed, and if so, if a floating-point co-processor is also installed. The current
versions of Kickstart and Workbench (versions 1.2 and 1.3) do not distinguish between
the MC68020 and MC68030, or between the MC68881 and MC68882. The CSA-MMR
program therefore determines which processors are actually installed. An MC68030
must be found or the program will exit without attempting to configure any of the 32-
bit memory resources. This allows the CSA-MMR program to be run safely at anytime,
even while in MC68000 mode.
