So; we've acquired a couple of machines based on an Asus A8N-VM CSM board
(http://usa.asus.com/products4.aspx?l1=3&l2=15&l3=210&model=766&a...),
with an Opteron 150. Uwe, this board costs $80 at Newegg so I guess it falls
into your cheap & common category.

This is the lspci output:

The intel ethernet controllers are plug in cards.

The SuperIO chip is - according to the URL pasted above - an Nvidia nforce
430MCP. The actual chip on the mainboard reads:

Nvidia
  P5080239 0534A2
  MCP51-N-A2
  GH 9940.1

The bios rom is an SST 49LF0048.

I tried flashrom. No dice:

# ./flashrom -V

601M loops per second
ok
No LinuxBIOS table found.

This is with the SST part switched in (biossavior). Similar problem with the
biossavior set to RD1:

Is there any hope for this board? If so; what should I try next?

I couldn't find a datasheet after a quick search,but maybe I missed it.
Does anybody have the datasheet?

I think this is a 49LF004B (notice 8 vs. B). Can you confirm that?

This should have worked and returned id1 0xbf, id2 0x60.

Thechip ID is the same as the one of the SST 49LF004A (which is
supported by flashrom). According to the datasheet they should also
be otherwise compatible.

I guess there's some motherboard-specific fixup required before flashrom
will work. You can use Uniflash or another board which is known to work
for flashing in the mean time, I guess...

HTH, Uwe.

That's correct. Should have paid more attention.

There must be, because flashrom also does not detect the other rom chip in
the bios savior, which works fine in the tyan boards.

Yes... or try to debug this to make flashrom work. How would I go about that?

Thanks,
Ward.

Ok. Above line is a good sign. It did not recognize the north bridge.
Please apply the attached patch and report to the list if it solves the
problem.

If it still fails:

* please send lspci -n as well 
 * send flashrom -V again...

Yep, that helped!

I've read both the original flash image and the bios-savior one. Reading is
*very* fast, not more than 2 seconds for the 512KB image.

I've also tried burning the original image (read via flashrom) to the bios
savior, but that failed:

# ./flashrom -v -w orig.img
Calibrating delay loop... ok
No LinuxBIOS table found.
Enabling flash write on NVidia MCP51...OK
Pm49FL004 found at physical address: 0xfff80000
Flash part is Pm49FL004 (512 KB)
Flash image seems to be a legacy BIOS. Disabling checks.
Programming Page: 0007 at address: 0x00070000
Verifying flash - FAILED

Writing was *very* slow - it took wel over a minute before it was done.

So; here's flashrom -V for the bios savior flash part:

# ./flashrom -V
Calibrating delay loop... Setting up microsecond timing loop
601M loops per second
ok
No LinuxBIOS table found.

can you do a -Vv to find out where it fails? And try writing several
times, then verifying to see if that helps...

Can you also try and check whether there's something else then 0xff in
the addresses that failed?

This is ugly, but probably not unusually slow.  :(

OK :) No big deal, really.

ok, some timing problem in the code, almost sure. I remember the
same code worked fine with my PMC4 bios savior...

It works fine with our bios savior in the tyan boards.

Ah, ok, of course. Here is the image I'm trying to burn back to the bios
savior:

So; first 8 bytes are all ff.

can you try to erase the chip, read it and see if its all FF?

something like:

flashrom -e 
flashrom -r tmp.out
xxd -g1 tmp.out|cut -c9- |sort -u

should not spit out more than a line of ff ff ff ff ...

[Stefan Reinauer]

And maybe try the attached patch, maybe play a little with the delay,...

*10,*100,*500,*1000

sorry, wrong diff :-( I messed it up.

The new one is correct.

It looks like the erase simply did not work (note that this chip contains an
old tyan s2882 image) - the image I read out after the erase is identical to
what I read out before the erase:

OK; with 200 microseconds, no difference:

Hi Stefan,

Any other suggestions to get flashrom to work on this board? Things I could
try?

Thanks,
