- No. The problem is in mixing a new SDMAC with an old Ramsey or
- an old SDMAC with a new Ramsey.

-
- The older Ramsey has problems with the page-detect mode. This was
- erroneously enabled when you have an 68040 board, Kickstart2.04 and
- static column DRAM. It can also be enabled manually with low-level
- tools like SetRamsey or SCRAMmer.

- >Seems with the updated Buster and DMAC yet an older Ramsey probs abound
-
- The problem is "an updated DMAC" and "yet an older Ramsey". You are not
- supposed to do that.
-
- >Adding an updated Ramsey cleared my probs up as also you have noted no
- >probs using the latest chips.
-
- Obviously, now you have again a working pair of SDMAC and Ramsey.
