Short: A tool to view/alter RAMSEY settings. Architecture: m68k-amigaos RAMSEY ======== Supervisor Software RAMSEY utility for Amiga 3000 computers version 1.02 This little program allows you to view, set, and reset the control bits of RAMSEY DRAM controller in A3000. This program is a replacement for a freely distributable program called SetRamsey, which seems to have some bugs (at least the version 1.02 does). Usage: ramsey [[NO]Page] [[NO]Burst] [[NO]Wrap] [Show] All command line arguments are optional. With no arguments, Ramsey lists the current configuration of RAMSEY: Fast1:Asm/Sources/Ramsey 8> ramsey RAMSEY: NOPage Burst NOWrap To get help of the command line arguments, type "ramsey ?", "ramsey ??" or "ramsey ???". Fast1:Asm/Sources/Ramsey 8> ramsey ??? *** Ramsey v1.02 *** © 1991 Supervisor Software Written by JM, August 13, 1991 Usage: ramsey [[NO]Page] [[NO]Burst] [[NO]Wrap] [Show] This command can be used to set and read the RAMSEY DRAM controller bits on Amiga 3000. Arguments (lower case chars optional): [NO]Page control page mode operation [NO]Burst control burst mode operation [NO]Wrap control burst wrapping Show list the current RAMSEY settings The lower case characters of the command line arguments are optional, so "nop", "nopag", or "nopage" will all turn page mode off. The Show command lists the RAMSEY revision number and current RAMSEY settings including DRAM type and refresh time interval. Please refer to Amiga 3000 techinal documentation for more information on the control bits and their meanings. Please send any comments, bug reports and benchmark results to jmarin@uku.fi or Jukka Marin Metsurintie 17 B 8 70150 Kuopio FINLAND A quote from Dave Haynie: "The 68030 will always request 4 longword values during a burst sequence. However, if initial longword is not aligned on a quad longword boundary (A3,A2 not equal to 0,0), the 68030 will read in data which is behind the first data it asked for. Since it is less likely that this data will actually be needed, RAMSEY can stop the burst sequence after the data with A3,A2=1,1 is accessed."
