ISA bus takes two cycles per transfer and transfers 2 bytes. Normal clock
speed is 16MHz, it gives 8M transfers per second and 16MBs. Perhaps your
bus gives 10M transfers per second (I don't believe that you have slowed
your bus :-) ) and 20MBs. But not 40.

> 100mbs.....
  ^^^^^^
Yes, 100 Mega bits (Mbs) per second, not Bytes (MBs) :-)
