But isn't the 386sx restricted in the amount of memory it can address? If
that's the case, then would a 386sx be able to run OS/2 ver 2.0 ? I guess
I'm wondering if the SX includes ALL the 32 bit machine instructions of a
DX? Furthermore, what is the size of the data path between a 386SX and a
387SX?
