Well, another incompatibility with OS 9 pops up.

It won't go to sleep properly. It goes to sleep, but the fans keep running (and as we all know, MDD fans are not quiet). It says there's a piece of hardware installed that's not compatible with sleep, and checking the system profiler, it appears to be a PCI card, of which there are none installed.

Could it be the graphics card itself? It's the GeForce4 MX, I think. It's whatever was the installed card on my FW800 board, and that being the lowend model, I think that's the one. I'll check later to be sure.

Any other ideas?
