SYMPTOMS
AST Research has confirmed that loading MS-DOS 5.0 and later EMM386.EXE on an AST Premium 286 computer with an AST 386 FastBoard upgrade may cause the following error message on startup:

EMM386 Privileged Operation Error #01

Deactivate EMM386 and Continue(C) or reBoot(B):



CAUSE
The AST 386 FastBoard is an 80386 upgrade for AST 80286 motherboards. This error may occur if the 386 FastBoard driver FB386.SYS is not loaded before EMM386.EXE in the CONFIG.SYS file.



WORKAROUND
Loading the 386 FastBoard device driver, FB386.SYS, before EMM386.EXE in the CONFIG.SYS file may correct the error. The following is an example of how the drivers should be loaded in the CONFIG.SYS file:

device=c:\fb386.sys

device=c:\dos\himem.sys

device=c:\dos\emm386.exe
