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-3300 mainboard, you have to fill the total 32-bit
memory in accordance with the switch setting for total on-
board 32-bit memory plus that on the PEI-306 32-bit exten-
sion memory card.
For example, if the switch setting for total 32-bit memory is
6MB, you’ll need 6MB (in some combination on the PEI-306
card and on the motherboard and 2MB) in your system
before you can add a 16-bit extension memory card. Other-
wise, there will be an address conflict for the memory.
