My R-11 C2, has crash after attempting to load a 17meg DXF files. My sys specs are: 486-33 clone, 12M Ram, 25M free Disk,DCA-11,DOS5.0 w/ 5M expanded, balance of ram extended. I might add, the system was working fine for about 1 week. This is a new system. My lastest error message is: 386|VMM stack pointer in unmapped pages. Sometime I get that error message and in addition the following: Memory Allocaton error Cannot load command. Please Help.

This particular "Unmapped pages" error is likely caused by a conflict in the way memory is split between expanded and extended memory, such that AutoCAD wanders into memory intended for other uses. You should check how your expanded memory is configured, and I hope you use QEMM. If you post the contents of your Autoexec.bat and Config.sys files we could help you out. Smaller drawings might not push you into the same memory areas. BTW, 25M free space is not sufficient to load in a DXF file of that size. Figure that you might need almost as much space for the resulting DWG file, and about 2-5 times that amount for AutoCAD's temp files and page swapping space.
