How do I get to the other 360K, designated as "expanded > memory"? In article <1407@lznv.ATT.COM>, psc@lznv.ATT.COM (Paul S. R. Chisholm) (that's me) writes at great length about how unlikely it is that you're going to be able to use that 360K as conventional memory. Well, as part of their Windows/286 (a.k.a. Windows 2.1) product, Microsoft is distributing a device driver that lets you get an extra 64K of conventional memory out of your extended (AT style, not LIM EMS) memory. This memory can be used by non-Windows applications. PC Week, July 11, 1988, p. 34: "As implemented in Windows, the driver conflicts with many existing memory management programs, including EMS emulators and virtual-disk [RAM drive] utilities." If all you needed was 704K total, and you're not using extended memory for anything else, you're all set. > A Dietz, Bellcore, Morristown, (ulysses, rutgers, bellcore)!mruxd!afd -Paul S. R.
