Lotus 1-2-3 Release 2.3
In order to configure EMS support for the virtual DOS machine, we must ensure
that a contiguous 64KB block of RAM is available in the address range 640KB
to 1MB to be used as the EMS Page Frame (Refer to Memory
Extender Support). Do the following:
Boot the system with the reference diskette and
in Set Configuration take a look at the memory map.
Print or make a note of the memory addresses
of the different hardware device drivers. For example, 3270 Connection may
have an address of 0D6000H (D6000 hexadecimal).
If a 64KB contiguous block cannot be found the DOS Settings for the
virtual DOS machine will have to be used to make a block available.
Reboot under OS/2 V2.0.
Open the Templates folder and drag a Program
icon to the desktop.
The Settings notebook should open.
Enter the following in the Path and file name
field (change the path according to your installation):
D:\123r23\123.exe
The Working Directory should be the same
as the path in the Path and file name field.
Select the Session tab.
Set session type as DOS Full Screen (Window will
work, but slower)
Open DOS Settings.
10.
Select DOS_UMB and set it to OFF (default
is ON)
11.
Select MEMORY_INCLUDE_REGIONS
and enter the addresses that you do not need for this virtual DOS machine.
For example, the 3270 Connection card is not used by Lotus 1-2-3 Release
2.3, so the device driver address for it (D6000) can be entered. Refer to
the online help for the syntax.
12.
Select
EMS_MEMORY_LIMIT and set it to accommodate the largest expected spreadsheet.
13.
Select SAVE to
save the settings.
14.
Select
the General tab and change the Title to "Lotus 1-2-3 Release
2.3".
15.
Close the Settings
notebook.
The Lotus 1-2-3 Release 2.3 icon should now be available for use.
