My bad. Sure there can be such kind of limits.

I'll think about it later. I got the box free, so i can test things
freely. Sure i will feel very bad if i broke something, but have to
look the memoryboard more closely to see if there is some kind of
marking about banks.

Actually i did forget the FreeBSD-port when i started yesterday. Just
trying to boot 5.1-RELEASE with 2 memorybords removed (the first boot
did hang)

Second one was different (only one 4GB board attached)

I don't mind the kind of *BSD as long i don't have to use Tru64 or
something else 'commercial, but not so sexy' (biased opinion) :)

Ok. Mine must be same then too. It's defiently 8400 case, but it's
detected as 'Compaq AlphaServer GS140 6/525, 523MHz' by NetBSD too.
