The 'barrier' is there because the 286 cannot access it without using protected mode. (Actually the first 64k of exTended ram can be accessed but this is another story) DOS cannot execute code from exTended ram, so programs must still fit into the 1st 640k. Virtual (Ram) disks, print spoolers, FastOpen (DOS 4.0), BUFFERS= (DOS 4.0), and exPanded memory emulators are some things that can use exTended memory. /--------------------------------------------------------------------------\ | Simon Gales@University of Ky UUCP: {rutgers, uunet}!ukma!simon | | Arpa: simon@ms.uky.edu | | MaBell: 263-2285/257-3597 BitNet: simon@UKMA.BITNET | \--------------------------------------------------------------------------/ -- /--------------------------------------------------------------------------\ Simon Gales@University of Ky UUCP: {rutgers, uunet}!ukma!simon Arpa: simon@ms.uky.edu MaBell: 263-2285/257-3597 BitNet: simon@UKMA.BITNET
