Although im probably grasping at straws with this one, here goes:
 
   A few months ago, i purchased my 486/33 AMI bios machine through the
classified ads in the local paper.  It is populated with 8 1MEG simms, filling
all of the slots.  I am interested in adding memory, going to 4meg simms,
the problem is that i have no documentation for the mother board.  Are there
jumpers or something that have to be set when changing the memory
configuration?  The most likely candidate i see for something like this is a
set of four dip switches, all set to the same position for the current config.
There is no manufacturer name on the motherboard (as far as i can see).. are
there any IC's that i could look for that might give me a hint as to how those
switches should be set if i add memory? (or if they have anything at all to do
with the memory?)  If anyone out there would be willing to help, please email.

PS - the bios date is mid 1991.
