Answer» Quote from: nymph4 on May 15, 2008, 12:26:14 PM Am I CORECT that you would need both EMM386.EXE and HIMEM.SYS to use Extended Memory? Yes. The HIMEM.SYS line must appear before the EMM386.EXE DEVICE line in CONFIG.SYS. This thread looks like you are studying for your A+ certification. I hope you are not doing all your learning on web forums!

To emulate EXPANDED memory, yes, to use extended memory no- Otherwise the 286 would have NEVER been able to use extended memory, since it can't use EMM386. (which might explain the name) And the EMM386 program can be run standalone, and will give some information and/or change settings when passed switches. why, I even fired up my old thinkpad just for you guys emm386 when run as a command gives me this: IBM Expanded Memory Manager 386 Version 4.50 Copyright (c) IBM Corp. 1986, 1994 Expanded memory services unavailable. Total upper memory available . . . . . . 0 KB Largest Upper Memory Block available . . 0 KB Upper memory starting address . . . . . .
