There are some Radeon cards that Elbox sold that are only partially supported (3.x only), hence the PCI.library ver 10 (download from Elbox's beta site). This is a kludge. I don't know if OS 4.1 Update 5 fixes this, but try another Video card. It seems this only pops up with the Radeon and they are well aware of the problem. Keep in mind that OS 4.1 wrote their own drivers for all the supported PCI cards to make the PPC compatible and "Radeon" defines only the chip set, not its implimentation on the card. A "quick and dirty" WinX driver can save money in the PC world, but not in a niche market like the Amiga.
