Couple more hints on Bob's CONFIG.SYS:

Thanx for the tip about /XMSUMB!  I'd forgotten that one.

In the 8 Septebmer 1998 release notes (DR-DOS 7.02) it mentions that 
the default of EMM386 is now to turn XMSUMB on, and the switch has 
been changed to /NOXMSUMB.

> BUFFERSHIGH=40 
> FILESHIGH=40

??? Are these new?  I see nothing listed in the documentation about 
these two commands.

> LASTDRIVE=Z 

LASTDRIVE is really only needed for Personal Netware.  If you're not 
running a network leave it off, or set it explicitly to the last 
drive letter you need.

> FCBSHIGH=4,4 

Could set FCBS to 0,0 -- most programs no longer use file control 
blocks but file handles.

> HISTORY=ON,512,ON

Could always reduce the history buffer if memory is really critical...

> COUNTRY=1,,C:\OPENDOS\COUNTRY.SYS 

If  you're running all US English programs on US English hardware you 
probably don't need COUNTRY.SYS

> STACKS=9,256 
> DEVICEHIGH = C:\WINDOWS\IFSHLP.SYS 

I believe IFSHLP.SYS is only required for Windows For Workgroups 
networking.  If you use Personal Netware you don't need this.
