Has anyone tried the MIPS port on old SGI tower case systems like Octeon?

[Jukka Ukkonen]

I did not try to say FreeBSD should support the old SGI iron.
I only wanted to state the fact that luckily there are alternatives
which being branches of the BSD family have pretty similar
behavior and general feel to them.
Nobody needs to change ones brain completely to start using
another BSD variant for a while. No worries.

The R10000, R12000 and R14000 CPUs all have TLB issues which force specialized trap handlers that are somewhat tricky to get right. It's a lot of work to get working and keep working for systems that are as fast as a Pentium III, but harder to get parts for...  There's no developers that has one in service, so while it would be nice if we ran on this cool, historically important MIPS flavor, the benefits haven't been there in the past, and are only less likely to be there in the future.
