    Three weeks later - is it soup yet ?
    
    (and what formats can I have it in - e.g. for this kind of document I
    find PDF is most useful).

139.8Are those definitive ? (Where's the PDF?)BBPBV1::WALLACEjohn wallace @ bbp. +44 860 675093Thu Feb 13 1997 14:268
    Are those the real thing ? The warranty procedure text up front isn't
    relevant outside the USA even though it claims to be, a German
    "warning" is missing in one of the early pages (heading but no text,
    unless my PSviewer got it wrong), and on p1.7 it talks about dual-cpu
    boards which I thought we weren't going to do ?
    
    regards

    I can't answer for the German-text being missing.
    
    The Dual CPU business we argued about, how to document.
    	The board is clearly dual cpu.
    		WE don't support that and haven't qualified it.
    			And don't Plan to, that i know of...
    
    To ignore it entirely in the manual would have seemed dumb.

Dave,

  My understanding was that the second CPU socket would not be installed on
the boards we are getting.  That's more than qualification issues.

When you say "clearly dual CPU", other than the silk screen and the 
documenation, what do you mean?

    The dialogue about differences is useful but meanwhile I'll simplify my
    basic question: Are those the definitive manuals ? I.e. can they be
    provided to customers ?
    1) Yes
    2) No

    What I think he means is looking at the board shows what seems to be a
    missing CPU.  There is not much way to hide it.  Curious customers will
    always ask the question [of you, or seek it in the
    glossies/documentation].

Ok, but it is quite common in the PC relm to see pads and silkscreens on 
motherboards where components can go.  I usually assume the motherboard is
sold into different markets with different features, 're-using' the same
design.  For example, I've seen common motherboards with pad locations for
ethernet, video, sound chips and, acutally, now that I'm thinking of it I
remember a motherboards that had what looked like a location for a second
processor.

I guess I also wanted to make sure that I was correct that it was more than a
missing CPU but all of the components needed to add the second processor are
missing on our processor card.  The only thing present for the second processor
is the silkscreen and pads.

139.14EBM3*-PA - Dual CPUNESBIT::RARMSTRONGWed Feb 19 1997 07:5322
Guys,
	I would like to clarify a few comments around the Dual CPU
RUSHMORE [EBM35,6,7-PA] variants.

Engineering have procured Dual processor variants and undertaken a
considerable amount of 'debug' and 'qualification' with two CPU
assembled. The boards are fully functional, pass the standard DVT
and qualification tests, and have met EMC Class A regulatory
approval. [We are currently going through Class B tests with new
etch design].

The revenue product has only the CPU zif socket and APICS chip
non-assembled. Bypass capacitors and 2nd thermal monitor chip etc. 
are left in situ. and as the astute have noticed, the silkscreen
is also un-modified.

Some minor effort is required to close out remaining engineering
activities, however these are not considered gates. This route was
taken to enable the OEM Business to have the option of a Dual CPU
product.

Ross.

139.16Final Manual now on-lineIRNBRU::GRANTIain Grant, E&RT, DTN 823-3532Mon Feb 24 1997 13:2910
The final manual for EBM3*-PA is now online.

The pointer in the documentation web pages has been updated to reflect this.
