AST OFFICE ADVANTAGE 386SX/20 AND WINDOWS 3.0
|
||
|
|
|
||
|
|
|
||
|
|
PROBLEM: When using the AST Office Advantage 386SX/20 with a factory
|
||
|
|
installed copy of Windows 3.0, Windows will not, by default,
|
||
|
|
run in 386 enhanced mode. By selecting "help" - "about" from
|
||
|
|
the Program Manager menu, Windows will show that it is
|
||
|
|
operating in "Standard Mode".
|
||
|
|
|
||
|
|
AFFECTED
|
||
|
|
SYSTEMS: AST Office Advantage 386SX/20
|
||
|
|
|
||
|
|
SOLUTION: Enter the system set-up screen by pressing and holding <CTRL>
|
||
|
|
+ <ALT> + <ESC> as the system boots. Following the
|
||
|
|
instructions on the set-up screen for moving the highlight
|
||
|
|
bar, move to the "Shadow BIOS" field and select "Disable".
|
||
|
|
Save the system configuration and reboot the system. By
|
||
|
|
disabling Shadow BIOS, an additional 128K of extended RAM will
|
||
|
|
be available for Windows. This additional extended RAM will
|
||
|
|
be sufficient to allow Windows 3.0 to operate in 386 Enhanced
|
||
|
|
Mode without any other modifications. Alternately, adding
|
||
|
|
additional memory to the system will also allow Windows 3.0 to
|
||
|
|
run in Enhanced Mode.
