According to the "documentation" with DOS 4.0, the driver XMAEM.SYS emulates expanded memory with any extended memory in the 386. But when I include DEVICE=XMAEM.SYS in my config file, I get the message "this system unit not supported". Then the DEVICE=XMA2EMS.SYS driver also complains, to the effect that there is no expanded memory. I have tried various permutations of RAMPage & RAMvantage cards setting up various amounts of conventional, extended, and expanded memory, all to no avail. Anyone have any ideas what I am doing wrong? Thanks in advance. Jeff Miller BITNET: jomiller@ucsd U. C.
