The screen N category is used to define the characteristics of each screen in the system. Currently, GEOS completely supports only one screen, which is called screen 0. This screen's characteristics are defined by the screen 0 category.
device = <device name>
This key specifies the full device name of the screen's device. The standard devices are shown in the examples below.
device = Hercules HGC: 720x348 Mono device = IBM MCGA: 640x480 Mono device = CGA: 640x200 Mono device = EGA: 640x350 16-color device = VGA: 640x480 16-color
driver = <file name>
This key specifies the file name of the driver used to run this screen.
driver = vga.geo
olddevice = <device name>
When the user switches between video drivers, the system keeps track of the old device name in case the user made a mistake and wants to switch back. It will store the old value of the "device" field in this field.
olddriver = <file name>
When the user switches between video drivers, the system keeps track of the old driver name in case the user made a mistake and wants to switch back. It will store the old value of the "driver" field in this field.
userdevice = <device name>
GEOS doesn't use this field. The Debug utility uses this field to store the user's personal video device choice when simulating hardware devices that would not support the choice.
userdriver = <file name>
