RESOLUTION

First you must determine what is causing your specific problem. Complete the following procedures in order. If the first procedure doesn't solve the problem, move on to the next one.

Step 1. Increasing Available XMS Memory

To determine how much extended memory is being used, at the MS-DOS command prompt, type: The MEM command will display information similar to the following:

       651264 bytes total conventional memory
       651264 bytes available to MS-DOS
       508736 largest executable program size

      1556480 bytes total in EMS memory
        55706 bytes free EMS memory

      4194304 bytes total contiguous extended memory
            0 bytes available contiguous extended memory
        48576 bytes available XMS memory
              MS-DOS resident in High Memory Area

The second line from the bottom displays the amount of XMS memory available. In the example, there are only 48576 bytes free. You need at least 393216 bytes to run Lotus 1-2-3 version 3.1.

To make more extended memory available, try the following:

• Make sure your computer has as much physical extended memory as the program needs.
• Make sure your CONFIG.SYS file contains a DEVICE command for HIMEM.SYS extended-memory manager (or another memory manager that conforms to the XMS specification). Most programs need an extended- memory manager to use extended memory.
• If your CONFIG.SYS file includes a DEVICE command for SMARTDrive, RAMDrive, or EMM386, these programs could be using too much of your extended memory. If so, reduce the amount of memory specified by editing the device command for each driver.
• Make sure your CONFIG.SYS and AUTOEXEC.BAT files don't start unnecessary programs that use extended memory.
• If you are using MS-DOS Shell or Windows, make sure XMS is enabled in the PIF (program information file).

Step 2: Running Lotus 1-2-3 Version 3.1 With Task Swapper

If you're using MS-DOS Shell and Task Swapper, you might solve problems running Lotus 1-2-3 version 3.1 by making sure enough XMS memory is specified. Before you can specify memory, you must have a program item for Lotus 1-2-3.

NOTE: If you don't already have a program item for Lotus 1-2-3, see page 187 in the "Microsoft MS-DOS User's Guide and Reference."

To find out if Task Swapper is enabled, open the Options menu by clicking Options or pressing ALT+O.

• If a diamond appears next to Task Swapper on the menu, it's active.
• If Task Swapper isn't active, your problem running Lotus 1-2-3 might be solved in the next section.

To specify XMS memory in MS-DOS Shell, follow these steps:

• Select the Lotus 1-2-3 program item.
• From the File menu, choose Properties.
• Choose the Advanced button.
• Move your cursor to the XMS Memory KB Required field and type 384.
• Choose the OK button.
• Try starting Lotus 1-2-3 again.

Step 3: Setting Up EMM386.EXE to Run Lotus 1-2-3 Version 3.1

If neither of the above solutions worked, you may have an 80386 processor with EMM386 set to run with the NOEMS option. This option makes expanded (EMS) memory unavailable. Because Lotus 1-2-3 version 3.1 and EMM386 both run in protected mode, they need to communicate to avoid conflicts. Lotus 1-2-3 and EMM386 can use a protocol called Virtual Control Program Interface (VCPI) to communicate. VCPI assumes that a page (expanded memory space) exists. A page is not available if EMM386 uses the NOEMS option. You must change the setting.

Edit your CONFIG.SYS so Lotus 1-2-3 version 3.1 works as follows:

• Use a text editor, such as MS-DOS Editor, to open your CONFIG.SYS file. If you want to use MS-DOS Editor, type the following at the command prompt:

edit c:\config.sys


• Locate the DEVICE command for EMM386.EXE. It should look like the following:

device=c:\dos\emm386.exe noems

NOTE: If there is no DEVICE command for the EMM386.EXE device driver in your CONFIG.SYS file, add one as described in the next step. Make sure that the line you add appears after the DEVICE command for HIMEM.SYS.
• Replace the NOEMS switch with the RAM switch. The device command for EMM386.EXE should look like the following:

device=c:\dos\emm386.exe ram

The RAM switch gives programs access to both expanded memory and the upper memory area.
• Save your CONFIG.SYS file and exit the text editor. If you're using MS-DOS Editor, choose Exit from the File menu. When MS-DOS Editor displays a dialog box prompting you to save your file, choose Yes, or press ENTER.
• Restart your computer by pressing CTRL+ALT+DEL.
• When your computer restarts, type the following to see a status report for EMM386:

emm386

The status report should look something like this:

Available expanded memory.......176 KB

LIM/EMS version..................4.0
Total expanded memory pages.......40
Available expanded memory pages...11
Total handles.....................64
Active handles.....................3
Page frame segment..............E000 H

Total upper memory available.......0 KB
Largest UMB available..............0 KB
Upper memory starting address...C800 H

The fourth line from the bottom shows you the segment where EMM386 is placing the page frame. For example, the address for the Page Frame Segment in the sample status report is E000. Write down the Page Frame Segment address from the status report on your screen.
• Open your CONFIG.SYS file again (see step 1 of this procedure).
• Locate the DEVICE command for EMM386.EXE, and after the RAM switch, add the following:

p0=<xxxx>

where <xxxx> stands for the Page Frame Segment value you found in Step 6. The DEVICE command for EMM386.EXE should look something like the following:

device=c:\dos\emm386.exe ram p0=e000

The P0= setting tells MS-DOS to use a page for EMS. Using a page instead of a page frame provides more space for programs in UMBs (upper memory blocks). A page frame requires 64K while a page requires only 16K, freeing 48K. The segment address tells EMM386 which segment is available for the page.
• Save your CONFIG.SYS file and exit the text editor (see step 4).
• Restart your computer again by pressing CTRL+ALT+DEL. When your computer restarts, you'll be warned that a LIM 3.2-compatible (64K) page frame does not exist. The standard size for a page frame is 64K, but since Lotus 1-2-3 is using XMS memory (not EMS), it only needs a 16K page.
• Try starting Lotus 1-2-3 again.
