evgainit -- Extended VGA keyboard/display driver initialization

Synopsis

evgainit card-type

Description

evgainit is used to initialize the keyboard/display driver (see keyboard(7)) if extended VGA graphics modes are being used on certain video cards.

The keyboard/display driver provides the interface to the video card. evgainit informs the keyboard/display driver which video card is installed and should be rerun each time the system is booted.

In many cases the keyboard/display driver can determine which card is being used and therefore this command need not be run. For example, you don't need to run evgainit for the following cards:

Any card that doesn't have extended VGA capability (that is, 800x600 pixels).
Any card that is only VGA (640x480 pixels) or EGA (640x350 pixels).
Any extended VGA cards (listed below) that will not be set to graphics modes with resolutions greater than 640x480 pixels.

evgainit must be run, however, for the following cards before attempting to use resolutions greater than 640x480 pixels. The following list shows the card-type argument value that should be used for each video card:

The command can only be run with appropriate privilege.

Examples

For an STB Extra/EM-16 video card, evgainit should be invoked as:

evgainit stbga

This command can be run automatically from the inittab file (see inittab(4)) or can be run by a user with appropriate privilege after each system reboot.
