-
- I have an MMR with 512KByte SRAM and no DRAM. I also have 8MB Ram on my GVP
- controller and 1MB Chip. I always copy my KS2.04 into SRAM, because that gives
- me the best performance increase. I have never had any trouble running in this
- configuration. Maybe there is a problem with your DRAM? But from what I know,
- the MMR configures it as memory above the first 16MB, so that there should be
- no address conflict of all your memory. If you have a SCSI controller with
- DMA access, then you might run into problem since it there is no way it can
- write directly to the 32Bit memory. But as far as I know, the OS will catch
- that and handle it by hand (i.e. making a buffer in 16bit RAM).
-
- If you find the problem please let me (us) know. I was also considering getting
- some extra 32Bit RAM. But I certainly don't want to run into compatibility
- problems.
-
- BTW... why do you have 13.5MB of RAM? (just kidding... :-)
