Loading pcANYWHERE into Upper Memory
-------------------------------------------------------------------------------
Upper Memory, unlike extended memory, does not physically exist when the
computer is turned on. It needs to be created by a program called a memory
manager. Memory management programs utilize a feature of the 386 and i486 micro-
processors which allows portions of extended memory to be changed into upper
memory. The Norton pcANYWHERE's Host program (AWHOST) can be loaded into the
upper memory area on a 386 or i486 based PC to provide more conventional memory
fo other applications. There are a few requirements which must be met before
the AWHOST program can be loaded into upper memory:
1. You must have a memory management program (QEMM, EMM386, 386MAX, etc.)
to configure your computer's upper memory.
2. There must be a contiguous block of upper memory large enough to
contain AWHOST. The smallest configuration of AWHOST (without Pop-Up
File Transfer and Maximized Display Speed) is about 60K. Pop-Up File
Transfer adds 17K, and Maximize Display Speed adds 46K to the total
memory requirements.
3. AWHOST needs to know the command used by your memory manager to load
programs into upper memory. To do this, select Preferences from the
Host Main Menu, and then select General. On the line which says
Command to load Host into high memory type your memory manager's command
to load programs into upper memory.
For example, LOADHI for QEMM, or COMMAND /C LH for EMM386 (the COMMAND /C in
required because LH is an internal DOS command). NOTE: If the directory
containing your memory manager is not in your path, you will need to specify the
full path to the memory manager command (i.e. C:\QEMM\LOADHI).
If the above steps are taken, AWHOST will load itself into upper memory.
Special notes for 386MAX memory manager users:
1. Include the host command line parameters "awhovl1 -m=a(w)" in the
autoexec.bat file.
2. Run "MAXIMIZE" which is the automatic system configuration utility.
3. In phase I of maximize you will be asked to specify Full or Quick
maximize, choose FULL MAXIMIZE.
4. In phase II of full maximize specify the command line for pcANYWHERE
in the autoexec.bat file as one of the programsto be considered for
loading into the high memory area.
5. 386LOAD will then specify the region size required for loading the
resident program, then it will use the command line FLEXFRAME to borrow
the EMS page frame area while loading a resident program.
6. After optimization simply remark this line from your autoexec.bat file
and include that in a host batch file.
Example:
@ECHO OFF
CLS
CD\AW
C:\386MAX\386LOAD SIZE=62944 FLEXFRAME PROG=AWHOVL1 -M=A
CLS
