(that is what I am using). AIX on the IBM PS2 is berkley 4.3 port, or so I have been told. As we have never run it, I wouldn't know. Markw -- Mark Whetzel My comments are my own, not my company's.

The kernel was modified to support RT-isms, which had to be re-implemented in most cases, due to differences in the internal designs of the kernels. "Some more Berkeley stuff" is a 99% compatibility with 4.3 BSD on the system call level, while maintaining sVr2 (as defined by SVID) and 100% POSIX compliance. Same goes for the utilities code and availability. AIX/370 is very 4.3 BSD in its behaviour to a user who prefers that environment (and everything feels like SysV when you use "sh" :-) >>some work done by Locus. AIX project at LOCUS was a many years effort by one of the best collections of UNIX talents in the world. Not to minimize IBM's contribution, but calling what LOCUS did "some work" is a gross and unfair under-statement. Most of the LPPs, like compilers, WHIP, ATE, original GSL code, COBOL, and all kinds of other "applications" I have no idea exist are IBM's work. However, to my mind, applications do not define the "flavour" of UNIX. The kernel, C libraries support and tools, on the other hand, do. -- "No regrets, no apologies" Ronald Reagan Oleg Kiselev ARPA: lcc.oleg@seas.ucla.edu, oleg@gryphon.COM (213)337-5230 UUCP: [world]!{ucla-se|gryphon}!lcc!oleg

Anyone can get a crude idea of the original source for kernel modules on AIX
PS/2 by running the what command on the kernel libraries in /usr/sys/386.
A quick look at those modules that have embedded sccs strings shows
that about half are labeled IBM and half are labeled LCC.

That's very misleading. All of AIX code (kernel, utilities and applications) are copyrighted by IBM and the executables are supposed to have IBM copyright imbeded in them, unless some other entity holds explicit copyright and either licenses software to IBM (Locus' PCI and MERGE code) or releases the software in some other way (University of California, Berkeley, owns copyright on most of the 4.3BSD TCP/IP code and 4.3 utilities). A lot of AIX PS/2 code carries LCC SCCS id strings, a lot of code does not -- regardless of whether the code was developed at LCC or at IBM. -- "No regrets, no apologies" Ronald Reagan Oleg Kiselev ARPA: lcc.oleg@seas.ucla.edu, oleg@gryphon.COM (213)337-5230 UUCP: [world]!{ucla-se|gryphon}!lcc!oleg

I believe a different group/company was responsbility for release 2.x of AIX on each of the different IBM platforms (i.e. PS/2, RT, 370). I think more of 3.x was done in-house using as much common source as possible; hence AIX should look almost identical on each platform.
