In addition to Apple's machines (like the 9500 180/MP like Rogerio mentioned) that came SMP-ready, and CPU upgrade cards, there were also clones at this time that were also SMP-capable. I remember a 4-way 604e non-Apple Power Mac. Since all of this arose from the same line of motherboard and chipsets, I would guess these machines also have SWIM3 controllers for the floppy drives. But just to clarify: I presently do NOT have SMP on my 8500. I have a single G3 CPU upgrade card. I've compiled a kernel with SMP set, and tried to use SMP-compatible locking primitives in my 1st attempt to make the SWIM3 driver SMP safe. But I did not use these properly. My attempt here is to try to do several things in one job: get my 8500 and all its hardware working, learning about device driver programming, and making code SMP-safe. If desireable, I can send the patch to the current 2.6.12 line to get the driver to compile cleanly. All I did was to replace the older interrupt calling routines with their updated equivalent. cheers vinai -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
