Your problem is simply this: If you have any 16 bit RAM installed, you must be
sure that you have NOT MORE than 7.5 meg of total RAM including the 4 meg on
the accelerator. That accelerator does not map its 32 bit RAM out of
autoconfig space, so you cannot have more than 7.5 meg of total RAM. If you
have any 16 bit RAM disable some of it. You may not be able to disable 16 bit
ram in less than 2 meg increments, which will reduce your total fast ram to 6
meg. You don't need to worry about the data cache on the 2620. The 020 only
has an instruction cache, so that shouldn't be a problem. However, judging
from your message, I would bet you have too much fast ram for the BB to run.
