This is caused by different methods of testing memory
among BIOSes. The solution is to set the switches for the
total 32-bit memory in accordance with the physical DRAM
installed. Most of the BlOSes do not have this problem.
If you want to add a 16-bit extension memory card to the
PEM-3301 mainboard, total 32-bit memory must match with
the switch setting for total onboard 32-bit memory plus that
on the PEI-306 32-bit extension memory card.
For example, if the switch setting for total 32-bit memory is
6MB, you’ll need 6MB (on the PEI-306 card and onboard
together in some combination) of actual system memory
before you can add a 16-bit extension memory card. Other-
wise, there will be an address conflict for the memory.
