I am trying to use windows effectively in both an AT&T PC6300 as well as an
AT&T PC6386 WGS.  In the 6386 I have 3M of extended memory which I have
configured as 200k of Ramdrive, 400k of Smart Drive and the rest as plain
extended memory.  Windows 2.03 finds the extended memory with no problem and
appears to use it effectively (greedily?).  The Ramdrive appears to only be
used for temporary files; the cache appears to do a pretty good job of 
buffering the hard disk as I keep it compacted.  Is there a different
configuration that might be more optimum?  Windows seems to be relatively slow
when I use a COMMAND window and run Dos programs, e.g. chkdsk.

I have recently put^expanded memory into my 6300.  I have followed the Windows
1.03 manual in trying to set it up, but it does not seem to be effective.
In particular they indicate that a large Ramdrive is the best way to have
memory for swapping.  Again the Ramdrive seems to only be used for temporary
files.  I have both the Ramdrive that came with 1.03 and the Ramdrive for
Dos 3.3 and see no difference.  All of the applications (that came with
Windows) appear to stay resident in the lower 640K.  Also there seems to be a
lot of swapping activity with the hard disk, but I cannot find any temporary
files (using Norton Utilities) that were generated during the session.  Any
help in getting this configuration optimized would be appreciated.

An unrelated item is that there is a program called WIN86.EXE in the WIN/386
package.  Before I got extended memory I could not get WIN386.EXE to run
because of insufficient memory (I have since found out how to do so).  However,
WIN86 would run.  I believe that WIN86 is called by WIN386.  What additional
capabilities are made available by WIN386 and is WIN86 equivalent to WIN286?

Thanks for any information you can give me.  Please reply to one of the
Email addresses below unless you feel it is of general interest to the net.

Thanks again,
