Just writing in to let you know that the Gigabyte P55A-UD4 seems to work fine.
hello!
Hi!
there are two revisions of your motherboard according to gigabyte. namely rev 1.0 http://www.gigabyte.com/products/product-page.aspx?pid=3239#sp and rev 2.0 http://www.gigabyte.com/products/product-page.aspx?pid=3436#sp
the only difference visible on that pages is the ethernet controller and small layout changes. i dont think those differences matter for flashrom at all, but just for the record: which revision do you have?
I wasn't sure either, so I downloaded both, and it turns out they have the same bios image.
But since you asked, I had another look. It's a bit hard to say. The box says rev 1.0, but looking at the images, I think it's right.
* Mine has the "EuP Ready" text in the corner near the DIMM slots, which only appears on the rev 2 picture. * I do not have the additional text near the dolby logo on the rev 2 picture. * The cap near the USB header (to the left of the dolby logo, at the edge) is in the position in the rev 1 picture. * The ethernet stuff looks more like the rev 1 pic. The "NEC" text is missing, but that cap behind the audio header is missing, like in the 1.0 pic.
Weird. Either way, like you said, hopefully it doesn't matter.
you can probably tell from the images. the most significant difference is on the left border near the dolby logo.
Ideas?
probably nothing to fear. can you tell us which addresses are different?
Hmm. OK, I ran both images through od, and diffed those.
I see four changed chunks:
0x0ff000 - 0x0ff04f (Block of all 0xff, replaced with data) 0x1ec000 - 0x1ee4ff (almost all 0xff replaced, also a "fffe 0000" pattern) 0x1eeff0 - 0x1ef65f (another block of all 0xff, replaced with data) 0x1feca0 - 0x1feca9 (just a couple bytes)
I'll put the bsdiff between the images on the paste site you mentioned below.
when did you read out the other file: before or after rebooting?
I think it was after rebooting. Anyway, I tried it now, (several reboots later), and the result is the same as the image I read back then. (ie not quite matching the one I wrote)
please dont post (binary) files containing (parts of) your bios (due to copyright problems for us). please you upload them to http://paste.flashrom.org/ instead.
OK, the bsdiff is there:
- Your paste can be seen at http://paste.flashrom.org/view.php?id=579 - Your upload can be seen at http://paste.flashrom.org/view.php?id=580
we (or at least i) consider this board as supported, so no other action then answering the revision question is needed from our (my) side.
Cool, thanks!
thanks for your report!
Thank you!
