The problem in question was IMHO non-existing adapter memory (the MDA frame buffer on an S3 card running in color mode). You can never be sure about misbehaving hardware in such cases. That's not only video-card related, it's also imaginable with memory-mapped ethernet cards, for example. > Does the broken system also hang for 64-bit video accesses via the FPU?
