+Some controllers have limitations with the way they deal with >16MB of memory,
+due to the fact that the ISA bus only has a DMA address space of 24 bits.

 If you do your arithmetic, you'll see that this makes it impossible to do
 direct DMA to any address >16MB.  This limitation is even true of some
 EISA controllers (which are normally 32 bit) when they're configured to
 emulate an ISA card, which they then do in *all* respects.  This problem
 is avoided entirely by IDE controllers (which do not use DMA), true EISA
