Unix OS for 286

Post by Scott Philip Sab » Sat, 17 Apr 1993 07:47:45



  I am in desperate need of any and all help!!! I am currently trying to
  find a Unix OS for an Intel 286 machine. I have tried a number of
  OS's, including Minix (Shows Booting Minix 1.5 prompt, then garbage),
  Linux (Seems to be CPU Specific. Does nothing), Xenix (Also seems to
  be CPU Specific. Runs to the Insert Floppy FileSystem prompt, then
  reboots the system.) I have also tried SCO Unix, which does the same
  thing as Linux. (Nothing!) Please, help me out. Any responses should

Get yourself a copy of Coherent.  It's sold by Mark Williams Company, and
comes in two flavors, v4.0 and v3.2.  You won't be able to use v3.2 --
becuase it requires a 386, but v4.0 should work.  MWC charges $99 for
either version, regardless of price.  They do include nice documentation,
and their o.s. is much more stable (if it doesn't include as many nice
features -- like TCP/IP networking).  

A few notes -- you will be limited to programs that fit in 64K of ram.  You
won't be able to run X.  There are probably other limitations as well.  This
is because the 286 is an old cpu which doesn't have as much support for
protection and large-space addressing as the 386.  Coherent 3.2 is the only
286 based version of Un*x I know of worth messing with.

On a side note: if you're going to do anything real with Unix, get yourself
a 386 or 486 and save yourself some headaches. :-)

PS: There is a group devoted to Coherent on the internet... comp.os.coherent,
I think.

I have Xenix 286 available for $100 (plus the developement system for $100)
if anyone is interested.

I'm normally not the type to respond to my own posts, but noticed the
following error:

That should be that you won't be able to run 4.0, but you should be able
to run 3.2.  I haven't been getting much sleep lately -- CS classes,
programming for work, and hacking Linux have all taken their toll. :)

BTW, I own both versions and would be willing to sell them, only becuase
Linux is so Cool :).  The two versions are against one license, so you
would be legally bound to run only one or the other version of the OS, at
least at the same time.  (No copies on different computers.)

If you're interested, make an offer.  I'd need to verify that this is legal
under MWCs license (i.e. transfer of license).

This is good advice--just one problem...it's   W R O N G.

Coherent version 4.x and (potentially) higher require a 386, minimum.
For a 286 you could use 3.2.1 or earlier.

Except for that little problem, though, it's good advice.

Also, you might be able to find an old copy of Xenix/286 floating
around somewhere which should also work for you. I doubt if SCO still
sells it, though.

Linux is 386-specific, unfortunately.

>Linux is 386-specific, unfortunately.

Frankly, I think the proper "unfortunate" fact is that 386 machines
are still out of the financial grasp of many people (most notably
students, who also generally seem to be the most enthused about PC
Unices).  I don't find it unfortunate that Linux doesn't run on a 286
any more than I find it unfortunate that it doesn't run on a 4004.

A 386sx is a drop in the bucket these days.  Even a full fledged dx cpu is a
commodity.  If you're willing to spend the time to look in a magazine like
Computer Shopper and maybe assemble systems yourself, a PC can be very cheap.
386DX-33 motherboard w/CPU    ~$210
4 megs ram                    ~$135
Case and power supply         ~$80
Floppy drive                  ~$40
VGA card                      ~$70
Mono VGA monitor (all you really need) ~$150
2400 baud modem               ~$40
100 meg hard drive            ~$225
Multi I/O card                ~$15

Total:                         $965

You can also salvage many of these parts (vga card, floppy drive, case).  
Granted, this is a minimum system, but it is very usuable.  I've seen postings
about people running 386bsd on a 20MHz 386sx (price: ~$150).

Even cheaper if you don't want to run X (and if you only have 4M you don't
want to run X).

My mono card cost me $7, and the monitor cost $15. I got two floppy drives
for $20 each, and 2 used ESDI hard disks for $25 apiece.

        In the Washington Post Business section today there is advertised
a 386SX40 motherboard for $99.00.  If one added memory at $33.00/Mb one
could have a Linux compatible system for about $250.00, by using the parts
from the 286 system.

Not correct. ( Only a mistake, I think.)

V 4.0 needs 386 or 486
V 3.2 will run with a 286

But the rest is right:

: A few notes -- you will be limited to programs that fit in 64K of ram. ..

I don`t know much about 3.2, I am running 4.0 and I'm very pleased about it.

But wouldn't it be fortunate if you could get Linux up and running on a
Sun 3/80 (68030) for a price much less than a 386 or 486 PC?

  The difference in cost between the 386SX and 286 is pretty small these
days. Anyone who can afford enough memory and disk for UNIX should be
able to find $50 or so more.

I use Coherent 4.0, the 32-bit 386-specific version, on a 16-mhz 386-SX.
It has 2 MB of RAM, and the 45 MB hard drive is divided evenly down the middle.
22.5 MB for DOS/Windows3.1 (which I can run just fine, thank you), and 22.5
for Coherent. Obviously, I'm not running gcc or X11R5 on my computer, but
I can use Coherent very well...

 Are there any other similiar versions that can run on a 286? Please email me i
