`devg-radeon.so`

Graphics driver for ATI RADEON chipsets

Syntax:

io-graphics -d radeon [option[,option...]]
            ... &

Options:

For the general io-graphics options that can be used with this driver, see io-graphics.

Description:

The devg-radeon.so driver provides accelerated 2D support for the specified graphics chipsets.

The DVI (digital video interface) is enabled by default, so you can connect LCD panels to your Radeon cards. The only requirement is that you connect the LCD to the DVI connector at boot time so the video BIOS can set up the digital output.

Dual-headed display is supported on cards with dual outputs. (x86 only) The video BIOS initializes both outputs at boot time. Ensure that both outputs are connected.
