- Very easy: If it's not present, CyberGfx is not installed and you can hack
- all you want.
-
- But if it *is* present, you should use the fast gfx-board instead of the
- slow custom chips.

- A built-in c2p routine (expandable of course) is planned for the next

- Using CyberGfx you are supporting about 95% of all gfx-boards, if it's not
- CyberGfx it's pretty safe to say that it's native.
-
- BTW: Even the Draco uses CyberGfx and AT stated that CyberGfx3.0 will be
- part of the new PPC-Amiga OS.
-
- Do you still have a problem supporting CyberGfx?
