[comp.sys.ibm.pc.hardware] i386DX, help needed

jacma@IDA.LiU.SE (Jacek Malec) (01/16/91)

On behalf of my friend, who cannot post, I'd like to ask the following
questions concerning i386DX processor residing in an AT board and
intended to run Unix:

1. We have been told that up to (?) 25MHz version, the 386 processor
   had to have the
   sigma-sigma
   sign on it to be able to run Unix (for DOS it had to be sigma-pi).

   Is it still true for the 33MHZ version? (we have the processor
   without any such sign).

2. We have been told that "D" version of the processor is error-free.
   Does the DX mean that we have D-version (we have a processor with the
   following set of inscriptions:

   i386
   A80386DX-33  IV
   SX219
   L0291855
   INTEL (m) (C) '85

3. Where can we find the program testing the multiplication error
   (which has been announced in '87)?

These are all specific questions I have been asked to post. Maybe you
have some other comments about Unix running on such processor?

I would greatly appreciate e-mail answers to me (jam@ida.liu.se),
possibly with a Cc: to marekk@amargosa.uucp, the original source of
question.  But I'll try to read these groups for some time.

TIME is important, as they have possibility to exchange the processor
or the whole motherboard up till the end of January.

Thanks in advance

Thanks to everybody, who answered to my (or our) questions.  It seems
that we don't have to worry, and that our 80386DX-33 should be OK.

However, one particular question seems to have received contradictory
answers. Some answers claim that "sigma-sigma" (or other) sign has
been used only up till 20MHZ version and should not appear on faster
processors.  Other people claim that they have it on their 33MHz chip!

So if you are not bored by answering me, please do it once more. My
questions are now the following:
1. What means (or has ment) the "sigma-sigma" sign on the processor?
   (Intel's final sign of approval?)
2. What means (or has ment) the "sigma-pi" sign on the processor?
3. Where can I find some (printed?) info about these matters?
4. Is there any contact in Intel, Inc. (e-mail?) where I could try to
   get some "official" answer? (I'm currently trying to find such in
   Intel-Sweden, but no success yet:-()

If possible, please answer by e-mail (jam@ida.liu.se) and Cc: to
marek@amargosa.uucp

Thanks in advance

I have a 386/25 that is about a year  old, it has the Sigma-Sigma sign on it.
I have also looked at several brand-new 386/25's that does not have this sign.
I have not looked closely at our 386/33.

There is a program called Check-It (offhand, I forgot who makes it.  It is not
PD or shareware).  This diag program will check a 386 CPU for the 'pre-sigma-
sigma' bug.

I was under the impression that the 'pre-sigma-sigma' bug was fixed before the
33mhz part was out.  Or even before the 25mhz.  But I have no REAL information
to back this up.

Gee, you mean someone actually tried to SELL such a program?  Included in
this posting is a PD checker from my archive.

I think the problem was solved back in the 16 mhz days.  The 16 meg
Compaq that is now the terminal I'm typing on has a double sigma symbol on
the 386 and I remember that it was quite a concern back then.

sci240s@monu6.cc.monash.edu.au (mr w.j. ho) (01/22/91)

Is there any known bug for i486 ( 25 Mhz or 33Mhz ) ?
If there is, anyway to check for it ?
