Depending on the motherboard, the answer is yes and yes and maybe. this site runs an Intel 386 motherboard with a total of 2.5 MB of 32 bit ram. I have 2 MB of 16 bit ram which I switch in to play with VP/ix (SCO's DOS virtual machine). Despite warnings in the SCO documentation, I have not identified any errors caused by 16 bit memory on the Intel motherboard. However, 16 bit memory causes programs to run very slowly, equivalent to a 4 mHz AT. So, the system runs faster without that memory. If there were a way to specify the 16 bit memory (higher addresses) were used only for buffers, I'd turn it back on. If you get a motherboard with cache memory, the performance hit from 16 bit memory might not be so terrible.
