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. -- Steve Dyer dyer@ursa-major.spdcc.com aka {ima,harvard,rayssd,linus,m2c}!spdcc!dyer dyer@arktouros.mit.edu, dyer@hstbme.mit.edu
