But the memory management features found in the 386, including the 386SX, can do more than providing EMS support through software. In my system I have 96Kb of high memory (above EGA memory, below BIOS) where memory resident programs can reside. I use 386-MAX to accomplish this and its easy to rearrange the memory into EMS or EXTended memory. Just small changes in CONFIG.SYS. As for the speed of the 386SX compared to the 286 I can only confirm that it is a bit slower at equal MHz's, but just a little. PC Magazine recently tested a number of 286 systems. Their conclusion was: By at least a 386SX!
