Les,

  It's a Win95 ONLY addition to DOS=. I've found that I get a better DOS
memory configuration with it and now use it by default.

  Below is a Cut & Paste from the file C:\WINDOWS\CONFIG.TXT file on it.

DOS
====

Specifies that MS-DOS should maintain a link to the upper memory area,
load
part of itself into the high memory area (HMA), or both. You can use
this
command only in your Config.sys file.

Syntax

    DOS=HIGH|LOW[,UMB|,NOUMB][,AUTO|,NOAUTO]

    DOS=[HIGH,|LOW,]UMB|NOUMB[,AUTO|,NOAUTO]

    DOS=[HIGH,|LOW,][UMB,|NOUMB,]AUTO|NOAUTO

Parameters

UMB|NOUMB
    Specifies whether MS-DOS should manage upper memory blocks (UMBs)
    created by a UMB provider such as Emm386.exe. The UMB parameter
    specifies that MS-DOS should manage UMBs, if they exist. The NOUMB
    parameter specifies that MS-DOS should not manage UMBs. The default
    setting is NOUMB.

HIGH|LOW
    Specifies whether MS-DOS should attempt to load a part of itself
into
    the HMA (HIGH) or keep all of MS-DOS in conventional memory (LOW).
The
    default setting is LOW.

AUTO|NOAUTO
    Specifies whether MS-DOS should automatically load Himem.sys,
Ifshlp.sys,
    Dblbuff.sys, and Setver.exe device drivers if they are not
explicitly
    loaded in your Config.sys file. The default setting, AUTO,
automatically
    loads these device drivers. The AUTO setting also automatically uses

    the BUFFERSHIGH, FILESHIGH, FCBSHIGH, LASTDRIVEHIGH, and
    STACKSHIGH commands, whether the -HIGH form of the command was used
    or not. If you specify the NOAUTO parameter, you must explicitly
load these
    device drivers and explicitly use the -HIGH form of the above
commands in order
    to take advantage of them.

  Later.
