Just got my "new" 1100E from "down-under" and I flashed my BIOS to the BP6RV128.BIN version a few minutes ago. I now have a working pair of 1100E's again !
V1.0, Rev. .40 board has all required changes except for wiring on back side of ZIF sockets.
I have been testing this BIOS/board combination for stability pushing the 366's to the limit, still stable @ 572.
