Amiga has NetBSD.. Works pretty good, too, and is binary-compatible with the Mac version. > BTW, Multibus and QBus had autoconfig way before 1986, FWIW. AutoConfig was a trademark of Commodore. The Zorro I and II buses were basically a local bus (straight off the 68000 chip), but Zorro III was an asynchronous bus that could adaptively negotiate clock speed and feature set with individual cards (backwards compatible with Zorro II, but Zorro I was very shortlived). But come to think of it, since all of the cards were memory-mapped, and the 680x0 has shared IRQ and DMA channels, there was only the memory range to allocate to AutoConfig it. Interestingly, the OS was smart enough to boot off of hard drive controller boards by loading in the driver from a ROM, and could also AutoConfig RAM expansion boards and add the RAM to the free memory pool... ---Jake
