But if you use some other BlOSes with the switch settings (SW1-1, SW1-2, SW1-3) for total 32-bit memory larger than the physical DRAM installed, there will be an error message. 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 mainboard, total 32-hit memory must match the switch setting for total onboard 32-bit memory plus that on the PEI-307 32-bit extension memory card. For example, if the switch setting for total 32-hit memory is 6MB, you'll have to fill out the complete 6MB (5MB onboard and 1 MB on the PEI-307 card) on the system before you can add a 16-bit extension memory card. Otherwise, there will be a memory address conflict. Video Selection Switch SW1-4 is used to select color or monochrome display modes. Refer to the figure below for the jumper settings.
