Insufficient Resource Memory Problem

Insufficient Resource Memory Problem

The most frequent problem reported is that LLRA displays an Insufficient Resource memory error when you attempt to launch it. This error is a bit ambiguous, because there are many types of Windows resources. It does not refer to the USER or GDI Resources that most status programs display, but to the amount of DOS allocatable memory that is available below 1MB.

LLRA requires 100K of this memory in order to load LLRA2 and LLRA3. I have only found two utilities that report on the availability of this type of memory. Manifest from Quarterdeck (included in QEMM ver. 7.5) displays this under its Windows|Memory option. SysInfo from Central Point Software (included with PCTools For Windows) displays it under Windows|Memory as well.

Of course knowing you have less than the needed 100K and being able to do something about it are two very different issues! Here are some tips that will help you get up and running:

  1. 1. Load LLRA1, LLRA2, and LLRA3 before launching Windows.
This method almost always works as LLRA doesn't need to load anything extra after you launch Windows. Its only drawback is that you lose about 74K of memory when shelled to DOS. If you are using LLRA only for periodic backups, this is the best solution and you can simply create a batch file to do this.

  1. 2. Launch Windows with WIN /N to prevent network drivers from loading.
If you are running a Windows For Workgroups network, it will need to load its drivers in the same area that LLRA wants to use. This is guaranteed to cause a Resource error. If you absolutely need both at the same time, then use Method #1 above.

3. Reduce your display resolution.

The amount of allocatable DOS memory is directly impacted by the resolution and number of colors you are using. Try running Windows Setup and selecting the standard VGA driver or reducing the resolution of your specific video driver.

  1. 4. Increase your lower DOS memory before launching Windows.
Since this Windows resource is not of a pre-defined size, the amount of free memory that you have prior to launching Windows will govern the amount of DOS allocatable memory you have under Windows. If you have less than 540K (run MEM.EXE to find out) you most likely can create more space by loading some of your drivers and TSRs into upper memory or extended memory. Utilities such as EMM386 (included with MS DOS), QEMM, 386max, and Netroom can do that for you.

  1. 5. Shell to DOS and return to Windows.
This tip pertains to those that get this error intermittently if LLRA works when you first start Windows but stops if you launch it later. As you use Windows, the lower DOS memory can get fragmented. Shelling to DOS will clean up this memory and should permit you to launch LLRA.

If none of these help, you may be able to get some clues from the fact that programs and drivers need this DOS memory when they must be accessible in a DOS shell from Windows. This is why Network drivers cause a problem.
