hi
I need help.
The case concerns a 1990 laptop - Commax Excell lt-386sx.
Built-in vga graphics card is Cirrus Logic 510/520.
Laptop seems to be fully functional now, but....
I can not switch between the built-in screen and the external monitor.
In bios settings there is no such option. I did not find any combination of keys that would work.
I searched the internet and found an article ( August '91 "PC Magazine" ) from which it appears that the manufacturer added an application that changed the working modes - also switching internal/external monitor.
The utility is probably called 'switcher.com'
I tried the 'eagle.com' application, but it requires a video bios in minimal version 3 (here is 2.22)and program does not start.
Maybe someone has such or similar computer model and this program ( probably switcher.com )
I will be grateful for any information.
