i have been fiddling with the early startup, i had it configured as "no
maprom" & "70ns RAM".

I changed both of these and workbench doesn't boot if i change either of
these, no matter what combination i try. Although if i have maprom with
70ns it works OK, what is the option "Free Configure" in the RAM section ?

If i try 60ns at all my system doesn't work properly, workbench comes up but
no backdrop is rendered and little works.

that sounds like my RAM!!

Is there any brand/supplier that 60ns RAM is known to work properly or is it
just by chance!

what config do other users have, i have a 200/040 @ 25 card, anyone else
with this card got 60ns RAM working ?
