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? How would this be done? -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
