Is it possible to add graphic words that can draw shapes to OpenBIOS? Does OpenBIOS have these words already? I was studying Apple's implementation when I discovered these drawing words.

You may not have a video screen - IEEE 1275 is supposed to work on serial lines.

Aren't those words defined on the VGA node? I remember OpenBIOS exposing less words than I saw in the specs. Andreas -- SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer; HRB 16746 AG Nürnberg

There are, but FCodes should not depend on them. The should work on a serial line (at least, back in the ieee 1275 days that was the standard). The VGA stuff was generally intended for printing a pretty banner.
