I was about to say "you can't" because "AIX" doesn't mean ANYTHING but
an interface specification.  Right now, AIX PS/2 and AIX/RT are completely
different internally.  The system call interface is mostly V.2 with sockets.
But if you work with the PS/2 kernel code (which I have) it's clear that it's
a Locus kernel, meaning that it shares a pedigree with 4.[123]BSD, V7, Sys III,
along with V.2, but has gobs of original Locus code to support TCF file sharing
and replication.
