IT IS POSSIBLE TO LAUNCH DOS AS A "SUB-PROCESS" ON OG 100!
When I have completed my version of OG TEXT MODE and having
received similar product (driver) from Marcus Groeber, I tried
DOS prompt the same way it can be evoked from GEOS on PC.
You need:
1. OG TEXT MODE DRIVER
(either OGTMODE.EXE by Marcus G., or my OGTEXT.COM)
2. COMMAND.COM from OG drive A:
3. Some aplications from GEOPUBLISH
\privdata\launcher.geo
\system\spool.geo
\system\shell.geo
\system\sysappl\manager.geo
Procedure (what I have done):
NOTE: I am using INTERLNK from PC DOS to communicate with OG 100.
This increases the transfer speed to some 115 Kbit/sec.
1. Install the OG TEXT MODE DRIVER (please, read its instalation)
2. copy OG command.com from A:\ on B:\
3. change following line in CONFIG.SYS
old: Shell = a:\command.com /P
new: Shell = b:\command.com /P
4. copy PC GEOS files into following directories on OG
launcher.geo b:\geoworks\privdata
spool.geo b:\geoworks\system
shell.geo b:\geoworks\system
manager.geo b:\geoworks\world
5. RUN GEOS
* new icon (GEO MANAGER) should appear
* launch it
* select menu:
Utilities/Create Launcher
* an OG file selector will appear
- click onto the blank line to get to the b:\ where
COMMAND.COM is placed
- double click on the COMMAND.COM
* another window will appear, too big to fit onto OG screen
- press ENTER to continue (nothing to setup here)
* you will return to GEOMANAGER
- press "DOS" panel and you will see an icon with GEOS logo
and COMMAND label
DOUBLE CLICK THE ICON TO LAUNCH DOS FROM GEOS!
Ending remarks:
- Copy the COMMAND icon into WORLD directory to have in the HOME appl.
- I believe you can set other icons for other DOS appls.
- The DOS runs in BIG letter mode (INT 10/FN00) and the screen
has inverted color from GEOS (if you have inverted color in GEOS
DOS will be "normal")
- type "exit" to get back to GEOS
Enjoy it,
