Installing and Configuring Enhanced OS-9
Enhanced OS-9 for X86 PCAT 81
Sequential Device Support
VGA Graphics / Keyboard
VGA support is provided using standard VGA graphics screen and
keyboard. Most PC based systems use VGA keyboard as the default
device for user input. While this is not required for OS-9 based systems
it is a convenient way to initially setup systems for use with OS-9.
During the development of MAUI user applications, a serial console
may be the preferred method since the text based console may
interfere with the graphics application on the same device.
MULTI-TERM is a feature of the VGA Graphics/Keyboard console
driver which provides up to four virtual screens. Console users may
switch between screens by pressing an alternate function key
combination, such as <Alt> <F1>, <Alt> <F2>, <Alt><F3> or <Alt><F4>.
MULTI-TERM may be started automatically in the /h0/sys/startup file or
manually from the console by executing the following commands:
$ mshell -l <>>>/mterm1&
$ mshell -l <>>>/mterm2&
$ mshell -l <>>>/mterm3&

#define DS_SHIFT_LOCK0/* Keyboard Caps lock 0=off 1=on */
To change these options, edit the file

the sections as outlined above. Change as desired. Then, change to the
MWOS/OS9000/80386/PORTS/PCAT/SCF/SC8042M/DRVR directory
and type os9make.
