       Carl-Daniel, I didn't say our datasheetd differ.. What I have said is that I
did physical measurements on my motherboard and what I have measured didn't
match at all the pin-out into the datasheet!! (see my previous posts..)
 Maybe this is only a minor hardware issue and it doesn't impact the software at
all, but I prefered to signal it as an odd thing!..
 Maybe someone with a v2.0 revision of m57sli could confirm my statements..

Wow.  I'm glad I found this thread.  It helped me keep my sanity.

My M57SLI-S4 V2.0 board(s) arrived Friday and I spent most of today 
studying the laout of the I want to install LinuxBIOS on.  I was hoping 
to figure out how to enable the 2nd SPI chip that they have pads for.

I've verified what Florentin sees is true. The physical pinout of the 
IT8716F on the board does NOT match the public datasheet.  I've also 
made a discovery.  The die inside the part is rotated.  So the relative 
pinout _is_ the same only shifted.

Take the pinout of the datasheet and do a +31 on the pin numbers 
wrapping at pins that are > 128.  So Pin 1 of the datasheet is actually 
pin 32 on the board.  Then it all lines up nicely.

The key was the floppy signals. I noticed that the relative order 
matched the datasheet but only in the wrong location.  So then I started 
checking pins next to the floppy signals and it all began to make sense.

But I still don't yet know how to make the 2nd SPI part go using the 
signals routed on the board.

CS# from the IT8716F is routed up to R509 which is a zero ohm resistor. 
  If this resistor is in place then CS is hardwired to CS# on U5 which 
is the SPI chip that's loaded.  If you pull R509 then the CS# to both 
chips are free to be selected by (unloaded) Q2,Q43,Q4, and Q5 + 
resistors but I don't have the configuration mapped out.

It does not look like there is any easy way to re-enable switching 
between the SPI chips since you have to load several missing parts.

I'll probably just end up soldering on a 2nd chip and then wiring the 
CS# pins up to a switch like the other mods did.

They would be part of Gigabyte's patented hardware BIOS failover
technology I suppose.

Q4-3 and Q5-3 are both connected to the superio side of R509, so the
emitter if using PNP transistors.

Traces from Q4-1 and Q5-1 both run toward the flash chips so they
would be the collector.

Q4-2 and Q5-2 the base, with R91 before Q4 and R90 before Q5. The
other side of R91 goes to R389 which then goes to Q43-2. The other
side of R90 goes to R86 which then goes to Q2-2.
There are some vias on the traces between R{90,91} and Q{4,5} so they
are connected to something else as well. (But what?) There are also
vias on traces between R{86,389} and Q{2,43}.

Q43 and Q4 are driven at the same time, through R389 and R91
respectively. I wonder what the purpose of Q43 and Q2 is.

The pinout does indeed match e.g. a BC847 PNP transistor in SOT23
package.

R89 is between Q4-1 (U5-CS#?) and a power net, so would be the
pull-up for when Q4 is not driven to select U5.

There is certainly a corresponding resistor for Q5-1 but there's only
a via from the Q5-1 trace so it would have to be tested. My guess is
R130 (directly south of R129) since it's other end goes to U9-CS#.


  It does not look like there is any easy way to
re-enable switching
 between the SPI chips since you have to load several missing parts.
The switch mod can be simplified to use existing pads and no pins
have to be lifted from the flash chips anymore.

1. Remove R509.
2. Populate R89 and R130 with 10k or 100k pull-up 0402 resistors.
3. Solder the switch common to Q4-3 and switch between Q4-1 and Q5-1.

Of course this assumes that soldering 0402 resistors is considered
simple, which isn't likely true unless you're good at SMT soldering.


  I'll probably just end up soldering on a 2nd chip
and then wiring
 the CS# pins up to a switch like the other mods did.
Of course there could be some timer thingy to do failover, but I
think manual control is best. I think the spring-loaded switch is
as useful as any mechanism in this case.

Confirmed.
But not with SMD Resistors.

First I removed the R509.
As there are connections from R89 Left to U5 VCC; from R89 Right to U9 CS#; 
from R130 Left to U5 CS# and from R130 Right to U9 VCC I soldered normal 100k 
resistors between U5 VCC and U9 CS# and between U5 CS# and U9 VCC.

I know, that these cables to the sockel are not really fine, but i had no 
other solution for mounting the sockel on the mainboard and it works fine!

I added a sockel for the SPI-chips to be able to change the bios chip in an 
easy way. If someone is interested which sockels these are, they are 
manufactured by WELLS-CTI and have the part number 652C0082211-W003.
I payed about 8€ per part, and that sould be about 10$, without shipping 
costs. The distributer for these sockels was http://www.bfioptilas.com/.

(PS: thanks to Mr. A. v. Heydwolff for organising these sockels.)

A
friend of mine helped me with the soldering, but he said that it is nearly 
impossible to solder these resistors without industry-equipment.

       Great work Richard!
 In fact what you have found, confirms the theory of one of my cow-workers that
sometimes MB manufacturers ask chip makers to issue "custom" revisions for some
types of components used in new series of a MB. (Of course the specs of these
revisions remain strictly confidential naturally.. why they do this one can
simply wonder.. after all business is business so what?!..)
 Btw what are the issues that remain unsolved on this board? (I know, I know, I
have to check the wiki..). What is the priority for this board?

one of the main big things on that board is the missing ACPI implementation.
the other issues seem to be just little things:
flashrom isn't working when lb is booted.
you need "NoDDC2" in your xorg.conf, else the startup of the x-server is 
really slow.

IIRC Florentin wanted to trace this as well. Maybe you can coordinate? I
have no idea whether I have internet access tomorrow.
The patch below may help to force writes to the chip. Maybe you need to
comment out the other busy wait loops as well and replace them with
usleep(1000) or something like that.

   Great work Richard!
  In fact what you have found, confirms the theory of one of my cow-workers
 that sometimes MB manufacturers ask chip makers to issue "custom" revisions
 for some types of components used in new series of a MB. (Of course the
 specs of these revisions remain strictly confidential naturally.. why they
 do this one can simply wonder.. after all business is business so what?!..)
  Btw what are the issues that remain unsolved on this board? (I know, I
 know, I have to check the wiki..). What is the priority for this board?

 one of the main big things on that board is the missing ACPI implementation.
Yeah. Because of this, no soft power off, etc.

  the other issues seem to be just little things:
 flashrom isn't working when lb is booted.
It does for me on my v1.1 board.

  you need "NoDDC2" in your xorg.conf, else
the startup of the x-server is 
 really slow.
Yeah. I'm still not sure why this is.

Thanks,
Ward.
