You need windows/386 dated after September 1988. There are odd inter-
actions between the 386 and 387 which cause crashes in software that
does paging, link windows/386. For the 16Mhz 386's there was a special
chip called an Ironwood that could be installed under the 387 to fix
this problem. Microsoft fixed it them selves with Revsion D of 2.1.
