But there is a 64-bit port (which I ought to bring in to Tribblix)
And thank you so much for tribblix; I was about to give up on illumos after repeated trouble installing OpenIndiana on my laptop (Tribblix worked out of the box on the hardware). I’ve since picked up a copy of “Solaris Internals” and have spent some time appreciating Solaris. Kudos.
Both are good distributions, but I strongly encourage you to try Tribblix if OI is problematic; for whatever reason the latest OI installers do not seem to include the same amount of driver support as Tribblix, in my experience.
