Setting Sun SPARC video mode in OpenFirmware

Some, older video drivers specific to proprietary Sun video boards such most of their early once but also one of the last of it’s kinds Creator / Elite 3d do not have a mode-setting open source Linux driver. To set another video mode for those you “currently” need to do so from the OBP / OpenFirmware, such as:

setenv output-device screen:r1600×1000x66

Unfortunately usually the cards open firmware glue does not support any arbitrary mode with this so you need to check against a list of officially Sun supported modes, … :-/ However, you can at least test what you set with


though ;-)
