Hi all, On Thursday, Oct 12, 2006, Uwe Hermann said:
I'd really, really like to see a bunch of popular, cheap, mainstream boards supported out of the box. IMHO this is really essential to get more developers on board.
Looking at a few random shops here in Germany, it seems that the most popular brands are Asus, ASRock, MSI, Gigabyte for mainbaords in the price range of 40-80 Euros.
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&modelmenu=1), with an Opteron 150. Uwe, this board costs $80 at Newegg so I guess it falls into your cheap & common category.

I couldn't find a datasheet after a quick search,but maybe I missed it. Does anybody have the datasheet?
The bios rom is an SST 49LF0048.
I think this is a 49LF004B (notice 8 vs. B). Can you confirm that?
Trying SST49LF004A/B, 512 KB probe_jedec: id1 0xff, id2 0xff
This should have worked and returned id1 0xbf, id2 0x60. Thechip 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...

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.
You can use Uniflash or another board which is known to work for flashing in the mean time, I guess...
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... -- coresystems GmbH • Brahmsstr. 16 • D-79104 Freiburg i. Br.

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.

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

Writing was *very* slow - it took wel over a minute before it was done.
This is ugly, but probably not unusually slow. :(
OK :) No big deal, really. Thanks, Ward. -- Ward Vandewege <ward@fsf.org> Free Software Foundation - Senior System Administrator

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.

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: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 00 05 95 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 01 02 03 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 01 aa 00 ................ 00 00 00 00 00 00 00 00 00 00 00 00 00 50 00 df .............P.. 00 00 00 00 00 00 00 00 00 00 c0 00 11 22 10 00 .............".. 00 00 00 00 00 00 00 00 00 00 e9 93 00 00 00 00 ................ 00 00 00 00 00 00 00 00 00 c8 00 11 22 10 00 00 ............"... 00 00 00 00 00 00 00 00 01 02 03 04 05 06 07 00 ................ 00 00 00 00 00 00 00 00 08 0a 41 4d 49 42 49 4f ..........AMIBIO 00 00 00 00 00 00 00 00 10 02 00 00 01 aa aa aa ................ 00 00 00 00 00 00 00 00 20 00 90 03 0f 93 00 00 ........ ....... 00 00 00 00 00 00 00 00 48 00 00 00 00 aa aa aa ........H....... 00 00 00 00 00 00 00 00 4a 00 00 00 00 aa aa aa ........J....... 00 00 00 00 00 00 00 00 50 01 00 00 00 aa aa aa ........P....... 00 00 00 00 00 00 00 00 50 50 74 22 10 00 00 00 ........PPt".... 00 00 00 00 00 00 00 00 ff ff ff ff 78 56 00 00 ............xV.. 00 00 00 00 00 00 00 01 02 03 00 00 00 00 ff ff ................ 00 00 00 00 00 00 00 f9 a6 e6 00 00 06 00 46 2d ..............F- 00 00 00 00 00 00 01 02 03 00 00 00 00 01 54 89 ..............T. 00 00 00 00 00 00 03 52 52 43 43 48 48 00 00 00 .......RRCCHH... 00 00 00 00 00 00 0c f2 5c f3 45 f5 6f a7 f5 99 ........\.E.o... ...
