  • Microsoft Windows for Workgroups versions 3.1, 3.11

SYMPTOMS

The following error message may be displayed when you start your computer after installing support for Banyan Vines connectivity: 

   Cannot install protected mode mapping
This error message is displayed when WFWNET.DRV cannot load VINES.DRV.

CAUSE

This error message may be caused by a lack of available conventional memory.

WORKAROUND

To work around this problem, try to increase the amount of free conventional memory. (In one case, 390 kilobytes of free conventional memory was needed.)

MORE INFORMATION

This error message occurs in low memory situations when the VINES protect-to-real mapping code fails to get a low memory buffer that is needed for interrupts that pass a buffer of data. The default value is for the mapping device load library (DLL) to get one 16K buffer. You can change this by setting the following values in the VINES.INI file:

[communications] 

 bufsize=16384   ;size of mapping buffer
 buffers=1       ;number of buffers to get
