Whats the difference between the versions of qnx? I had one once, but i dont think it liked my card or something, cause it was very very very slow. I think it was QNX 4 or something... whats neutrino all about? what are all these QNXs?
Neutrino is the new name for the QNX Realtime OS from version 6.2 onwards. I think they changed it to distinguish between the company and the product a little more. I'm surprised to hear it was slow for you, I had QNX running on my stepdad's old P233 laptop once, and it was quite snappy. (Maybe I just have good luck with these things, people always seem to complain of AROS running slow too. Maybe I just have good hardware ;-))
Regarding the differences between QNX 4 and QNX 6.2, from the QNX website:
Like QNX 4, QNX Neutrino is a microkernel, message-passing, memory-protected operating system. But compared to version 4, QNX Neutrino lets you deploy systems on a much larger variety of processors, including PowerPC, MIPS, SH-4, ARM, StrongARM, XScale, and x86. It's also more scalable, with support for symmetric multiprocessing (SMP). And it provides a much richer set of POSIX APIs.
