Unloading some BSD/OS CD’s

I was kindly sent these a while ago from an avid reader, and I tried to get them to boot up into anything useful and didn’t get anywhere.  I’m sure emulators of today are probably up to task, be it Bochs/PCem/86Box or even Qemu.

So they are now up on archive where I also found version 4 up there so I may as well flesh out the collection.

Enjoy!

Probably figured out why Net/2 doesn’t work.

It’s not unresolved symbols, but rather deleted bodies…

: There are other similar functions.  Also, the standalone stuff needed
: for bootstrapping is incomplete.

Routines which are thus missing from the kernel are:
acct(), sysacct(), execve() with friends, physio(),
minphys(), rminit(), rmalloc(), rmfree(), ptrace(),
procxmt(), profil(),  cinit(), getc(), q_to_p(),
ndqb(), ndflush(), putc(), b_to_q(), nextc(),
unputc(),  bufinit(), bread(), breada(), bwrite(),
bdwrite(), bawrite(), brelse(), incore(), getblk(),
geteblk(), allocbuf(), getnewbuf(), biowait(), biodone()

I have looked them up in the unix v7 sources, and they amount to
approximately 800 lines of code.
Some I cannot find there. They are:
minphys(), rminit(), rmalloc(), rmfree(), procxmt(), nextc(),
unputc(), bufinit(), allocbuf(), getnewbuf()
Do they really containt AT&T code, or were they just kicked out "by
mistake"?

In any case, unless there are more surprises, it should not be too
hard to rewrite these routines. Many are quite straightforward.
Most routines contain 10-20 lines of code. One only 2.
Some are ridiculusly simple. In fact, I wonder how they can be
rewritten to not be identical with the AT&T ones. 

Now, I wonder, are these routines really identical to the Unix v7
routines, or are they modified by the BSD people?
That is, would it be possible to plug in the V7 routines, modify them,
and get it working, without having seen the actual bsd routines?

So that is probably why it ‘works’ but doesn’t work.  Oops.
