I client of mine recently upgraded from release 10 (DOS 286) to release 11 c2 (DOS 386) and today I was helping him install the upgrade. We have a problem getting the new software to work on his Epson Equity 386/20 with 2 MB RAM, 20 MB free disk space after the install, MS-DOS 3.3. The system hangs after the "Successful Login" message. Once it didn't even get that far – it crashed upon loading with the message "Fatal Error: FMTOUT 1". Release 10 still works. No hardware or other software changes were made. We have a Northway 386SX in the same office so we tried loading it there and it DOES work. Any ideas?

Ray, FMOUT error indicates a problem with the math co-processor. Be sure it is firmly seated and the motherboard jumpered or BIOS informed correctly. However, it is possible you receive the problem because of a low memory condition. AutoCAD rel 11-386 really needs 4M to be happy – 2M is probably the bare minimum for the program to even load (not necessarily operate), and you may have other things stealing some of the 2M anyway.

The coprocessor was firmly seated and the bios did recognize it. I increase RAM to 4 MB with no luck. I tried a plain vanilla boot-up with no autoexec.bat and only files=40, buffers=20 in config.sys with no change in symptoms. I tried DOS 5.0 without anything load high but no luck. I tried using the older version of the DOS Extender by running through the OLDDX procedure but no luck. I then tried it on a Espon 386/20 in MY office and the same problem occurred. The processor chip has A80386DX-20 on it. Is this the same as the B-step problem chips which have A80386-20 on them?
